Description

  The present invention relates to a measuring apparatus that measures, for example, an object to be measured or a signal to be measured and displays the measurement data. In particular, the present invention displays, for example, a measurement waveform based on measurement data, specifies a target point on the measurement waveform with a waveform marker or the like, and obtains a characteristic value of the measurement waveform at the specific point. The present invention relates to a measuring apparatus that can easily set a waveform marker as a target point.

  The operator manually operates an operation unit such as a mouse while observing the display screen to match the waveform marker (or called a marker, cursor, etc.) with the position of the target point on the display screen. If it is attempted to move, fine adjustment is difficult, such as passing through a target point. As a technique for solving this, there is a technique disclosed in Patent Document 1.

  In the technique described in Patent Document 1, the movement speed of the waveform marker can be set from the key input unit, and the movement amount of the waveform marker is obtained from the set movement speed and the number of display data on the display screen. The position of the waveform marker on the display screen is moved and adjusted by the obtained movement amount.

  According to the technique of Patent Document 1, since the moving speed of the waveform marker can be arbitrarily set, the cursor can be easily set at the target point.

  Also, as in Patent Document 2, a zone marker having a predetermined width is generated, the peak position of the waveform in the zone of the predetermined width is searched, and the peak marker is automatically added to the peak position of the waveform and displayed. There was technology to do. This is convenient for searching for a characteristic portion such as a peak position.

Japanese Patent Laid-Open No. 5-142262 Japanese Patent No. 2880711

  However, in the technique disclosed in Patent Document 1, the moving speed of the waveform marker must be switched and set by the key input unit. Generally, when moving a waveform marker to a target point on the screen, the operator moves the waveform marker by operating a mouse or the like with his / her hand while directly viewing the screen with his eyes. When the operator wishes to make fine adjustments while moving the waveform marker, in Patent Document 1, the operator must change the movement speed by a key operation, which is different from the movement operation of the waveform marker using a mouse or the like. Therefore, there is a possibility that the position of the waveform marker cannot be adjusted as if it flows smoothly. In particular, when the moving speed is switched to a plurality of stages, there is a drawback that the smoothness of adjustment is further lacked.

  In the technique of Patent Document 2, when there are a plurality of peak points in a zone, there is a possibility that a marker is displayed at another peak point that is not the desired peak point.

  An object of the present invention is to provide a technique that can smoothly adjust the position (movement) of a waveform marker by switching between coarse adjustment and fine adjustment in a series of marker operations by a single means. It is to be.

  Furthermore, when searching for peak points, it is possible to easily change the relative size between the display range in which measurement data is displayed and the predetermined width of the zone marker that is the range to be searched. It is to provide a technique for easily observing by separating peak points.

  Here, the “marker operation” in the present invention is an operation for moving the waveform marker by the operator, and is either direct (for example, operated with a finger (pointer) on the touch panel) or indirectly (a pen ( An operation such as an operation such as an operation with a mouse or the like, and a pointer marker (pointer) serving as a finger instead of a finger is displayed on the display screen.

Specifically, in order to achieve the above object, the invention described in claim 1 includes a user I / F unit (10) having an operation unit (12) and a display unit (11), an object to be measured or an object to be measured. A measurement unit (30) for measuring a measurement signal, and a data display control unit (61) for causing the display unit to display measurement data in a predetermined display range as a measurement waveform based on the measurement data obtained by the measurement unit. A zone marker generating unit (64) for displaying a position of a zone marker having a predetermined width according to a marker operation from the user I / F unit on the measured waveform, and a zone marker generating unit (64) in the zone marker having the predetermined width A display control unit (60B) having a peak marker generation unit (61b) for displaying a peak marker at the maximum position of the waveform, wherein the marker operation displays the measurement waveform of the display unit do it That in the waveform display area at a guidance is performed by moving the finger needle, further wherein the display control unit, said marker from said widthwise direction different from the other direction of the position of the finger needle at the start of the marker operation The relative distance to the position of the pointer moved in the other direction by the operation is detected , and based on the relationship between the relative distance stored in advance and the amount of change indicating the change in the predetermined display range, The amount of change corresponding to the detected relative distance is obtained, the previously set predetermined display range is changed and displayed with the obtained amount of change, and the width direction movement when the pointer moves in the width direction is displayed. A zone control unit (65) for detecting the amount, wherein the zone marker generation unit follows the detected movement in the width direction of the pointer on the measurement waveform of the predetermined display range changed by the span control unit. Moved to the position Is, the peak marker generating unit has a configuration for displaying the peak marker to the maximum position of the waveform in the modified said predetermined at a constant display range, and within the predetermined range of movement to the displayed the zone marker.

According to a second aspect of the present invention, in the first aspect of the invention, the span control unit further detects a center position of a predetermined width of the zone marker, and the measurement unit is detected by the span control unit . With the center position of the zone marker as the center, the predetermined display range is changed to a display range corresponding to the detected relative distance and displayed.

According to the configuration of the present invention described in claims 1 and 2 above, the operator moves the pointer continuously on the display of the display unit, and the predetermined range of the zone marker and the display range of the measurement data are displayed. Since the relative and effective resolution of the zone marker can be adjusted by changing the relative size of the peak marker, a plurality of peak points can be separated and easily captured by the zone marker.
In addition, since the relative and effective resolution of the zone marker can be smoothly adjusted while continuously moving the marker, the operation is easy.

  Here, for the present invention relating to the control of the amount of movement of the marker, the first embodiment using a touch panel having a sensor function on the screen of the display unit of the measurement apparatus, a normal display device having no sensor function on the screen was used. The description will be divided into the second embodiment. In the present invention for making it easier to set a peak marker in a zone by separating a plurality of peaks, examples of changing the zone width are measured data (measured by the measurement unit 30) in the third and fourth embodiments. An example of changing a display range that is a range for displaying a measurement waveform will be described in the fifth and sixth embodiments.

  The object of the marker operation described in the claims is to move the waveform marker via a pointer (marker) in the first and second embodiments, and in the third to sixth embodiments, via a pointer (marker). The zone marker is moved. In the third to sixth embodiments, the peak marker is automatically positioned at the maximum position of the waveform in the zone.

[First Embodiment]
A first embodiment will be described with reference to FIG. Here, for example, the measurement unit 30 sends a signal defined by the actual wireless system from the signal generation unit 30a to a device under test such as a mobile communication device, and receives a signal from the device under test by the signal analysis unit 30b. Then, the device under test is inspected by analysis. At that time, the received signal may be analyzed in the time domain, or the frequency spectrum of the signal may be analyzed in the frequency domain. When performing such an analysis, the received signal or a signal obtained by converting them is represented on the display unit 11 in time domain coordinates with the horizontal axis representing time and the vertical axis representing the level at that time (that is, the size of the measured waveform). Time domain measurement waveform 100 or a spectrum measurement waveform 100 represented by frequency domain coordinates with the horizontal axis representing frequency and the vertical axis representing the frequency level (measurement waveform size). The display control unit 20 displays them on the display unit 11. Note that the measurement apparatus to which the present invention is applicable is not limited to the one having the measurement unit 30 for inspecting the mobile communication device described above, and displays data obtained by measurement (including photographing) as an image. The waveform marker 110 is inserted into the waveform marker 110 to acquire image characteristics at the position of the waveform marker 110, for example, applicable to measurement fields such as shape measurement, flow rate measurement, and medical measurement (first to first). The same as in the sixth embodiment). However, in the following description, the measurement waveform is described as data developed with coordinates represented by the size of the measurement waveform in the vertical axis, such as time and frequency with the horizontal axis as the reference of analysis.

  The data display control unit 21 in the display control unit 20 stores the measurement waveform 100 from the measurement unit 30 in the measurement data storage unit 21a and the horizontal axis information (for example, time and frequency on the horizontal axis) when measured. The waveform size (corresponding to the position on the vertical axis) is stored as an address. Then, the measurement waveform 100 stored in the measurement data storage unit 21a is displayed on the screen on the display unit 11 together with the coordinates of the horizontal axis and the vertical axis.

  The marker generation unit 21b generates a waveform marker 110 having a form as shown in FIG. 2 and determines the horizontal axis position X1 based on information obtained from an instruction amount detection unit 22 and a relative distance detection unit 23 described later. The waveform size (Y1) at the address corresponding to the determined horizontal axis position is read from the measurement data storage unit 21a, and the measured waveform is on the horizontal axis-vertical axis coordinates displayed on the display unit 11. The waveform marker 110 is displayed on the top, that is, at the coordinates (X1, Y1). FIG. 2A shows a display example. In an initial state where there is no information from the instruction amount detection unit 22, the marker generation unit 21b gives a specific initial position on the horizontal axis. The movement instruction of the waveform marker 110 is performed by the pointer 150. In this example, the waveform marker 110 moves following the movement of the pointer 150 in the direction parallel to the horizontal axis. The distance (speed) at which the waveform marker 110 follows the movement of the pointer 150 changes depending on the movement distance (relative distance) of the pointer 150 in the vertical axis direction. Details will be described below.

  As shown in FIG. 2 (A), the command amount detection unit 22 displays the screen of the display unit 11 (a display area for displaying the measurement waveform 100, that is, an area in which coordinates indicated by the horizontal axis-vertical axis are displayed, and so on. The amount of operation when the pointer 150 is operated in a direction parallel to the horizontal axis (also the amount of movement of the pointer), for example, the operator touches the touch panel of the screen with his / her finger, When moving in the axial direction, the movement amount of the finger (pointer) (operation amount: hereinafter referred to as “movement amount” simply indicates the movement distance in the horizontal axis direction) and the movement direction, or the operator When touching the touch panel of the display unit 11 with a pen or the like to move the touched position, the amount and direction of movement of the pen or the like are detected. This detection is performed in a processing cycle that is faster than the movement time of the pointer 150. In the first embodiment, a finger, a pen, and the like will be described with the pointer 150.

  The regulation information storage unit 24 displays the magnitude of the movement change amount (hereinafter referred to as “movement amount”) of the waveform marker 110 that actually moves the waveform marker 110 with respect to the movement amount of the pointer 150. In correspondence with the distance in the vertical axis direction of the screen (corresponding to “relative distance” described later), it is defined in a plurality of stages n, and the regulation information is stored. For example, waveform marker movement amount = k × (pointer movement amount) / N; k is a proportional constant, N is a natural number, and the natural number N is divided into a plurality of stages n. The regulation information storage unit 24 also divides the relative distance into n stages, and stores the value of N as change information H (N) = (waveform marker movement) / (pointer movement) = k / N as regulation information. deep. In the following description, it is assumed that k = 1. For example, the first stage is stored as H = 1, the second stage is H = 1/2, the third stage = 1/3, and so on (in this example, n = N. Not limited to).

  The relative distance detection unit 23 detects the initial position of the pointer 150 in the vertical axis direction on the screen of the display unit 11, and then detects whether the pointer 150 is in any one of the plurality of levels in the vertical axis direction. In detecting the initial position, the relative distance detection unit 23 detects whether or not the pointer 150 is first placed, and detects the position in the vertical axis direction when it is first placed as a reference position. Then, any one of the plurality of stages n is assigned to the reference position. For example, the first stage (change amount H = 1) is assigned to the reference position. This is illustrated in the example of FIGS. In FIG. 5, when the relative distance detection unit 23 detects that the reference position (initial position) of the pointer 150 (position [1] in FIG. 5) is on the upper side of the screen, the relative position detection unit 23 sets the reference position to 1. The stage (H = 1), and as the position becomes lower, the second stage (H = 1/2), the third stage (H = 1/3), ..., the amount of change up to the sixth stage H is defined. In FIG. 6, since the reference position of the pointer 150 is low, it is defined from the reference position to the lower third stage. 5 and 6, each stage is shown as being divided into sections 160, but in reality, this section 160 is not displayed (may be displayed). The relative distance detection unit 23 detects whether the pointer 150 is initially placed, for example, there is a switch for turning on / off the waveform marker 110, and the pointer first arranged after the switch is turned on. 150 can be recognized as the first pointer 150. For example, when the pointer 150 moves in the vertical axis direction, the separation of each stage is recognized as the k-th stage when the pointer 150 moves in the vertical axis direction, and then moves continuously in the horizontal axis direction. The subsequent movement in the vertical axis direction may be recognized as the movement of the (k + 1) th stage, and the continuous movement in the vertical axis direction is set as the kth stage, after a predetermined time has elapsed or after a predetermined time stop (for example, , 0.2 seconds later) in the vertical axis direction may be recognized as the k + 1 stage movement.

  After the relative distance detection unit 23 assigns any one of the above-described multiple levels n to the reference position, the relative distance detection unit 23 detects how much the pointer 150 has moved in the vertical axis direction from the reference position. That is, the relative distance is detected. Then, it is detected which of the plurality of stages n the relative distance corresponds to, and the change amount H corresponding to the stage is read from the regulation information storage unit 24 and sent to the marker generation unit 21b. For example, since the stage n of the relative distance YL when the pointer 150 in FIG. 5 is lowered from the position [1] to the position [2] in FIG. 5 is the third stage, the change at this stage (n = 3). The amount H is read from the regulation information storage unit 24 as H = 1/3, and this is sent to the marker generation unit 21b. In the example of FIGS. 5 and 6, the change amount is assigned to the direction in which the change amount attenuates only from the initial position of the pointer 150 to the lower direction, but may be increased from the initial position to the upper direction. However, in general, in order to align the waveform marker 110 with the target point, it is sufficient to define the direction of attenuation. Further, although it can be attenuated in accordance with the relative distance in the upper direction, the sense of discomfort in operation will be less if the attenuation of the change amount H increases as the position of the pointer 150 decreases.

  Returning to the marker generator 21b, the description will be continued. The marker generation unit 21b stores the current horizontal axis position of the waveform marker 110. Then, when the pointer 150 moves in the horizontal axis direction without changing the relative distance (the position of the vertical axis) (for example, at the stage of n = 3) (positions [1] and [2] of the pointer 150 in FIG. 5) , [3] movement), the movement amount and movement direction of the pointer 150 are received from the instruction amount detector 22, and the movement amount of the waveform marker is obtained from the movement amount and the change amount H determined by the relative distance. That is, the horizontal axis position of the waveform marker 110 is determined as waveform marker movement amount = H (for example, 1/3 if n = 3) × (movement amount of the pointer 150). Then, in the direction in which the pointer 150 has moved, the waveform axis is the horizontal axis position where the current waveform marker position is moved by the calculated waveform marker movement amount, and the waveform in the measurement data storage unit 21a at the horizontal axis position. The waveform marker 110 is displayed at the vertical axis position indicated by the size of.

  The above-described series of operations “movement of the pointer 150 in the vertical axis direction—detection of the relative distance—determination of the change amount and movement of the pointer 150 in the horizontal axis direction—detection of the movement amount of the pointer 150 by the instruction amount detection unit 22 “The position determination and display of the waveform marker 110 by the marker generation unit 21 b” is performed in the above-described fast processing cycle while the pointer 150 is moving, and the position of the waveform marker 110 is sequentially updated. Therefore, although the movement of the pointer 150 and the movement of the waveform marker 110 are different in movement amount (distance), there is little time difference, and the waveform marker 110 can be moved without a sense of incongruity by an operation.

  Therefore, in other words, the movement amount (distance) of the pointer 150 is large and the movement amount (distance) of the waveform marker 110 is small at the same time. It can be said that the relative distance detection unit 23 and the marker generation unit 21b determine the moving speed of the waveform marker 110. That is, if each movement amount (distance) is expressed by speed (Vm, Vs), the waveform marker movement amount = Vm · t and the pointer movement amount = Vs · t. Therefore, the change amount H (N) = (waveform marker movement amount) / (pointer movement amount) = Vm · t / Vs · t = Vm / Vs = k / N. For this reason, the “movement amount” in the claims expresses both the concept of distance and speed. However, in the description of each embodiment, the movement amount as a distance will be described.

  The actual series of operations and the movement of the waveform marker 110 according to the first embodiment will be described in the order of steps in FIG. 8 based on FIG. 8 and FIGS.

Step S1; The measurement waveform 100 measured by the measurement unit 30 is generated and displayed on the display unit 11 having the touch panel structure, and the regulation information storage unit 24 classifies the relative distance by dividing the change amount H in six steps in advance, for example. According to the stages n = 1, 2, 3, 4, 5, 6, for example, the change amount H = 1, 1/2, 1/3, 1/4, 1/5, 1/6 is stored. ing.
Step S2: With the marker switch for setting the waveform marker 110 turned on (Marker on), the marker generating unit 21b generates the waveform marker 110 and displays it at a predetermined initial position.

  The data display control unit 21 uses a value on the horizontal axis (for example, time or frequency) and a value on the vertical axis (for example, the magnitude of the waveform at that time) of the measurement waveform 100 corresponding to the position of the waveform marker 110 by the marker generation unit 21b. Or the magnitude of the waveform at that frequency). See the measured value 140 in FIG. Thereafter, each time the position of the waveform marker 110 is updated, the measurement value 140 is also updated.

Step S3: The operator places the pointer (finger) 150 at the position [1] at the top of the screen as shown in FIG. 2A and moves it in the horizontal axis direction.
Step S4: The relative distance detection unit 23 determines whether or not the marker is the first pointer disposed first after the marker switch is turned on. In the case of the first pointer 150, the operation of step S6 is performed after the operation of step S5. After detecting that it is the first pointer 150, it is assumed that the next detected pointer 150 is not the first pointer 150, and the operation of step S6 is performed.
Step S5: The initial position [1] in the vertical axis direction of the first pointer 150 is stored as a reference position (see the initial position (reference position) Y0 in FIG. 3A), and n is added to the position [1]. = 1 is assigned, and the change amount H = 1 is read from the regulation information storage unit 24 and sent to the marker generation unit 21b.
Step S6: The relative distance detection unit 23 detects whether the movement of the pointer 150 is in the vertical axis direction or the horizontal axis direction. If it is the former, the process proceeds to step S7, and if it is the latter, the process proceeds to step S8. In FIG. 2A, since the movement is in the horizontal axis direction, the process proceeds to step S8, where the instruction amount detection unit 22 detects the movement amount of the pointer 150.
Step S7: If the pointer 150 has moved in the vertical axis direction, the relative distance detection unit 23 obtains the relative position from the reference position, and reads the change amount at the stage corresponding to the relative distance from the specified information storage unit 24. Then, instead of the previous change amount H = 1, it is sent to the marker generation unit 21b, returns to step S6, and waits for the next movement in the horizontal axis direction. In FIG. 2A, since the movement is in the horizontal direction, this step S7 is not performed, so that the change amount H = 1 remains.
Step S8; The marker generation unit 21b receives the movement amount of the pointer 150 in the horizontal axis direction as shown in FIG. 2A from the instruction amount detection unit 22, and detects the change amount H = 1 at that time as a relative distance. Received from the unit 23, the waveform marker movement amount = (movement amount of the pointer 150 from the position [1] in FIG. 2A to the position [2] in FIG. 2B) × H (= 1) Then, the waveform marker 110 is moved to the obtained horizontal axis position (see the position of the waveform marker 110 in FIG. 2B).
Second round steps S2, S3, S4, S6; FIG. 2B shows an example in which the waveform marker 110 has gone beyond the target point. Therefore, when the waveform marker 110 is displayed as shown in FIG. 2B (second round step S2), the pointer 150 is moved from the position [2] to the position [3] as shown in FIG. Lowered (second round step S3). The pointer 150 by this operation is not the first pointer 150 (second round step S 4 -No), and is the movement in the vertical axis direction (second round step S 6 -vertical). The relative position YL1 from the reference position (initial position Y0) is obtained, and the amount of change at the stage corresponding to the relative distance YL1 is read from the defined information storage unit 24. If the position [3] corresponds to three steps of the relative distance (n = 3), the read change amount H = 1/3 is sent to the marker generation unit 21b instead of the previous change amount H = 1, and step S6. The process returns to wait for movement in the horizontal axis direction (second round step S7).
Third round steps S3, S4, S6, S8; in order to further bring the waveform marker 110 closer to the target point 130 days by further operation, the pointer 150 is then moved from the position [3] in FIG. 3 (A) to the position in FIG. 3 (B). When moving to [4] in the horizontal axis direction (third round step S3), this is not the first pointer 150 (third round step S4-No), and is a movement in the vertical axis direction (third round step S3). From step S6—horizontal), the command amount detection unit 22 detects the amount of movement of the pointer 150 in the horizontal axis direction. Then, the marker generation unit 21b receives the movement amount in the horizontal axis direction from the instruction amount detection unit 22, and receives the change amount H = 1/3 at that time from the relative distance detection unit 23, thereby moving the waveform marker movement amount. = (Amount of movement of the pointer 150 from position [3] to position [4]) × H (= 1/3) is obtained, and the waveform marker 110 is moved to the obtained horizontal axis position (FIG. 3B). (Refer to the position of the waveform marker 110 in FIG. 1).
Subsequent multi-round steps S2 to S8; when the pointer 150 is moved from position [4] in FIG. 4A to position [5] and further to position [6] in FIG. The second and third round steps are repeated. In this case, if the position [5] in FIG. 4A is the fifth step (n = 5) in the relative distance YL2, the waveform marker movement amount of the waveform marker 110 = (movement amount from the position 5 to the position [6]). ) × change amount H (= 1/5). In this manner, the waveform marker movement amount with respect to the operation amount of the pointer 150 can be changed in order of 1/1, 1/3, and 1/5 in order, so that the waveform marker 110 can be easily aligned with the target point 130 (FIG. 4 (B)). Then, a measurement value 140 such as level and time at the position of the waveform marker 110 is read out. As described above, since the gear change is possible by changing the operation direction of the pointer 150 singly, it is very easy to operate.

  The operation of each step described above operates at a predetermined fast processing cycle during the movement of the pointer 150 in step S3. Therefore, the movement of the pointer 150 and the movement of the waveform marker 110 can be viewed as if they correspond immediately.

  To summarize the above operation, for example, as a result of moving the pointer 150 in FIG. 2A, the waveform marker 110 is moved at a speed (movement amount) of 1/1 with respect to the movement amount of the pointer 150. As a result, it is assumed that the waveform marker 110 is displayed at a position past the target point as shown in FIG. Next, the operator lowers the pointer 150 and places it in the third stage from the reference point as shown in FIG. Then, the waveform marker 110 moves at a speed (movement amount) of 1/3 with respect to the movement amount of the pointer as shown in FIG. It becomes easier to adjust compared to the movement speed (movement amount) of 1/1. Further, when fine adjustment is desired, the waveform marker 110 is moved to 1/5 of the movement amount of the pointer 150 by moving the pointer 150 in a state where it is positioned at the fifth stage as shown in FIG. Can be adjusted to the target point 130 as shown in FIG. 4B.

[Second Embodiment]
Here, the first embodiment of FIG. 1 uses a touch panel, whereas the second embodiment with the configuration of FIG. 9 uses a normal display device having no sensor function on the screen. It is. In the case of a touch panel, the touch panel itself can sense an operation with an operator's finger or pen and the operation content can be visually recognized. In the second embodiment, a screen is used instead of the operator's finger or pen. By displaying the pointer marker 150a that can be visually recognized at the same time and making the pointer marker 150a movable by an operation from the operation unit 42, the same functions and effects as those of the first embodiment are obtained.

  In the following, the points different from the first embodiment will be mainly described based on FIG. 9 having the same reference numerals as those in FIG. 1 have the same functions.

  The user I / F unit 40 and the display control unit 50 in FIG. 9 correspond to the user I / F unit 10 and the display control unit 20 in FIG. 1, respectively, but are partially different.

  In the embodiment of FIG. 9, the display unit 41 of the user I / F unit 40 displays a pointer marker 150a as a substitute for the pointer 150 of the display unit 11 of FIG. The pointer marker 150a is moved by a mouse or the like in the operation unit 42 operated by the operator. The pointer marker generating unit 25 of the display control unit 50 generates the pointer marker 150a, receives the movement of the mouse or the like in the operation unit 42 as an operation amount encoded by the encoder, and selects the pointer marker 150a according to the operation amount. Move (see arrow mark in FIG. 10).

  The instruction amount detection unit 22 in FIG. 9 detects the operation amount of the operation unit 42 such as a mouse in response to the movement amount in the horizontal axis direction of the screen from the pointer marker generation unit 25. When the amount of movement of the pointer marker 150a in the horizontal axis direction on the screen by the pointer marker generator 25 is the amount of movement of the pointer marker 150a as it is, the instruction amount detector 22 is not necessarily required (instruction amount detection of FIG. 9). Reason why the portion 22 is surrounded by a dotted frame). Further, the relative distance detection unit 23 of the display control unit 50 in FIG. 9 receives the position information of the pointer marker 150a that the pointer marker generation unit 25 has moved in the vertical axis direction of the screen by the operation amount by the movement operation of the mouse or the like. The relative distance (step) is detected, the change amount H corresponding to the detected relative distance (step) is specified from the regulation information storage unit 24, and is sent to the marker generation unit 21b.

  Other configurations are the same as those of the first embodiment. In other words, the pointer 150 in the description of the first embodiment is the same as the pointer marker 150a.

  Corresponding to FIG. 2A which is a display example of the first embodiment, a display example of the second embodiment is shown in FIG. The pointer 150 only replaces the pointer marker 150a.

  A flow showing a series of operations of the second embodiment is shown in FIG. 11 and FIG. 8 are different in that “pointer” in FIG. 8 is read as “pointer marker” and that the pointer marker 150a is displayed and moved in step S2a. The operation of other steps in FIG. 11 is the same as that in FIG.

(Modification 1)
In any of the above cases, the relative distance is set in the direction parallel to the vertical axis of the coordinates of the screen of the display unit 11, and the change amount H is set according to the relative distance from the reference position of the pointer (marker). The movement of the pointer (marker) in the horizontal axis direction is configured to move the waveform marker 110 by an amount defined by the change amount H. However, as a modification, the relationship between the vertical axis and the horizontal axis may be reversed. . That is, as shown in FIG. 7, the relative distance YL from the reference point is set in the direction parallel to the horizontal axis of the screen, and the movement amount in the vertical axis direction is an amount defined by the change amount H corresponding to the relative distance. The structure which moves the waveform marker 110 may be sufficient. This can be applied to both the first and second embodiments.

(Modification 2)
In the first embodiment, the reference position is set to the position where the pointer 150 is first disposed after the marker switch is turned on. However, when the display unit 11 is a touch panel, the reference position is The position touching the touch panel can be set as the reference position. That is, the reference position may be reset and updated each time the pointer 150 is detached from the touch panel and retouched. In this case, the relative distance detection unit 23 can cope with this by updating the reference position each time it detects the detachment or retouch of the pointer 150.

[Third Embodiment]
The third embodiment includes a zone marker 170 having a variable width, and functions as a peak marker 180 that displays the waveform marker 110 in the first embodiment at the peak point of the measurement waveform 100 in the zone marker 170. It is something that has However, as described above, the zone marker 170 is directly set as an operation target by the operator.

  A third embodiment will be described with reference to FIG. In FIG. 12, the main parts denoted by the same reference numerals as those in FIGS. 1 and 9 have the same functions.

  The data display control unit 61 in the display control unit 60 stores the measurement waveform 100 from the measurement unit 30 in the measurement data storage unit 61a and the time information (corresponding to the position on the horizontal axis) in the measurement time range when measured. The waveform size (corresponding to the position on the vertical axis) is stored as an address. And the waveform data memorize | stored in the measurement data memory | storage part 61a are displayed on the screen on the display part 11 as the measurement waveform 100 with the coordinate of a horizontal axis-vertical axis (refer FIG. 14). The display unit 11 will be described as being configured with a touch panel. The marker operation (170 movement operation described later) will be described in the form of using a finger as a pointer as in the first embodiment.

  The zone marker generating unit 64 has a default position and width when the apparatus is switched on, and thereafter a position (hereinafter referred to as “zone position”) and a width according to an instruction from the position detection unit 63a described later. A zone marker 170 (hereinafter sometimes referred to as “zone width”) is generated and displayed on the display unit 11. In this case, the zone width is changed around the designated zone position (zone center position). FIG. 14 shows an example of a rod-shaped zone marker 170 having a predetermined zone width.

  The peak marker generation unit 61b receives the zone position and zone width information from the position detection unit 63a (or from the zone marker generation unit 64), and calculates a time position and a time width corresponding to the zone position and zone width information. Then, the measurement data of the measurement waveform 100 at the time position and the time width is read from the measurement data storage unit 61a, and the peak value of the measurement waveform 100 within the zone width is obtained. Then, a peak marker 180 is generated and displayed at the peak position of the measurement waveform 100 (see the ▽ marks in FIG. 14). The data display control unit 61 allocates the measurement time range to a physical full-scale range (for example, 512 dots) on the display surface of the display unit 11 and displays it. On the other hand, since the zone position and the zone width are the physical position and range of the display surface of the display unit 11, the peak marker generation unit 61b receives the zone position and the zone width and stores them in the measurement data storage unit 61a. The time position and width are converted with reference to the measurement time range.

  The regulation information storage unit 63b is divided into a plurality of stages n in the vertical direction of the pointer 150 (corresponding to a relative distance, which will be described later) before shipment or measurement, and the change amount Hw ( The rate of change) is memorized. For example, similarly to the steps in the first embodiment, the amount of change Hw is 1/1, 1/2, 1/3, 1/4, 1/5 as the position of the pointer 150 is lowered. A value that makes the zone width narrower, such as 1/6, is stored (not limited to six levels. It may be continuous or may be identified and displayed step by step. May be the reverse of the above.) Also, the absolute value, for example, the first step is (physical full-scale range on the horizontal axis) / 10 (for example 50 dots), and the second step is (on the horizontal axis). (Physical full scale range) / 20 (for example, 25 dots),... Hereinafter, the change amount Hw will be described.

  As shown in FIG. 14, the position detection unit 63a of the zone control unit 63 is a screen of the display unit 11 of the touch panel (a display area for displaying waveform data, that is, an area in which coordinates indicated by the horizontal axis-vertical axis are displayed. This is the same meaning.) The amount of movement in the zone width direction when the pointer 150 is operated in order to move the zone marker 170 above (the amount of movement in the horizontal axis direction; hereinafter referred to as “width direction movement amount”) And the position in the vertical axis direction are detected. For example, the movement amount of the finger (pointer) in the width direction and the vertical axis position when the operator touches the touch panel of the screen with the finger and moves the touched position (the position of the pointer 150) are detected. This detection is performed in a processing cycle that is faster than the movement time of the pointer 150. In the third embodiment, a finger, a pen, and the like will be described with the pointer 150.

  And in the detection of the vertical axis position by the position detection unit 63a, the initial position of the pointer 150 in the vertical axis direction is detected on the screen of the display unit 11 like the relative distance detection unit 23 of the first embodiment. After that, it is detected whether it is in any one of the plurality of stages. That is, the following processing is performed. The position detector 63a detects whether or not the pointer 150 is first placed, and detects and stores the vertical axis position when the pointer 150 is first placed as a reference position. Then, any one of the plurality of stages n is assigned to the reference position. For example, the first stage (change amount H = 1) is assigned to the reference position (see FIGS. 5 and 6. FIGS. 5 and 6 are diagrams for the first embodiment. The same applies to the third embodiment). In the case of FIG. 5, the initial position of the pointer 150 (the position [1] in FIG. 5) is the first stage (change amount Hw = 1), and the second stage ( Hw = 1/2), the third stage (Hw = 1/3),..., And the relative position (stage n) up to the sixth stage are assigned to define the change amount Hw of the zone width. In the case of FIG. 6, since the initial position of the pointer 150 is low, it is defined from the initial position to the lower third stage. The position detection unit 63a is the same as the detection by the relative distance detection unit 23 of the first embodiment in the detection method for determining whether or not the pointer 150 is first placed and the detection method for the vertical axis position.

  After detecting the initial position, the position detection unit 63a assigns one of the above-described plurality of steps n using the initial position as a reference position, and then the relative distance detection unit 23 determines which pointer 150 is in the vertical axis direction from the reference position. Detects if it has moved about. That is, the relative distance is detected. Then, it is detected which of the plurality of stages n the relative distance corresponds to, and the movement change amount (ratio) Hw corresponding to the stage is read from the regulation information storage unit 63b, and the zone marker generation unit 64 and the peak marker generation unit 61b are read out. Send to. At this time, the position detection unit 63a also detects the movement amount in the width direction of the pointer 150, and sends the movement amount in the width direction together with the change amount Hw to the zone marker generation unit 64 and the peak marker generation unit 61b. For example, in the case of FIG. 5, the stage n of the relative distance YL when the pointer 150 is lowered from the position [1] to the position [2] in FIG. 5 is the third stage, so this stage (n = 3). Hw = 1/3 is read out from the regulation information storage unit 63b as the change amount Hw at, and is sent to the zone marker generation unit 64 and the peak marker generation unit 61b. Then, the amount of movement in the width direction of the pointer 150 is also detected, and the amount of movement in the width direction is sent to the zone marker generation unit 64 and the peak marker generation unit 61b together with the change amount Hw.

  By doing so, the zone marker generating unit 64 generates the zone marker 170 having the zone width multiplied by the change amount Hw instructed from the position detecting unit 63a to the default zone width on the display unit 11 as described above. In the zone position corresponding to the movement amount in the width direction instructed by the position detection unit 63a. On the other hand, the peak marker generation unit 61b changes the change instructed to the default zone width around the time position (horizontal axis position) determined at the zone position corresponding to the movement amount in the width direction instructed from the position detection unit 63a. The waveform data of the measurement waveform 100 within the time width corresponding to the zone width multiplied by the amount Hw is read from the measurement data storage unit 61a, and the waveform position indicating the maximum value is obtained from the read waveform data. The peak marker 180 is attached to the waveform position and displayed.

  It should be noted that the time from when the change instruction is made with the pointer 150 until the zone marker 170 and the peak marker 180 are displayed at the changed positions is processed at a high speed. The width and zone position can be changed, and the result can be known smoothly (smoothly).

  Next, a series of operations including the usage method will be described with reference to the display examples of FIGS. 14 to 17 (partly overlap with the above description).

  In FIG. 14, the horizontal axis indicates the measurement time, and the vertical axis indicates the magnitude of the measurement waveform 100. Here, the operation from the position of the zone marker 170 in FIG. 14 to setting to the target point 130 (◯ mark) to be measured will be described. In FIG. 14, the zone marker generation unit 64 displays a zone marker 170 having a predetermined zone width at a predetermined zone position as a default, and the peak marker generation unit 61 b displays data of the measured waveform 100 within the zone position and the zone width. This is a state where a peak marker 180 is searched and a peak marker 180 is displayed at that position.

  In FIG. 14, the operator places the pointer 150 (finger) on the display surface ([1] position in FIG. 14) and moves it toward the target point 130. The position detection unit 63a detects the vertical position of the placed pointer 150, stores the position as a reference position (first stage), and detects the amount of movement in the width direction of the pointer 150 in the horizontal axis direction. Then, the first stage change amount Hw = 1/1 is read from the regulation information storage unit 63b and sent to the zone marker generation unit 64 and the peak marker generation unit 61b. Since the change amount Hw = 1/1, the zone marker generation unit 64 keeps the width of the zone marker 170 as the default zone width, and the position detection unit 63a detects when the pointer 150 moves in the horizontal axis next time. The zone marker 170 is moved to the zone position (position [2] in FIG. 15) corresponding to the movement amount in the width direction. The peak marker generation unit 61b reads the waveform data of the measurement waveform 100 within the time width corresponding to the default zone width at the destination zone position (position [2] in FIG. 15) from the measurement data storage unit 61a. A waveform position indicating the maximum value is obtained from the read waveform data, and a peak marker 180 is added to the position and displayed (marked in FIG. 15).

  In FIG. 15, the peak marker 180 is at the peak position next to the target point and has not yet reached the target point 130, so it is necessary to further narrow the zone width. Therefore, the operator lowers the pointer 150 in FIG. 15 from the position [2] to the position [3] in FIG. 16, that is, in the second stage (relative distance) in the vertical axis direction. Then, the position detection unit 63a detects the vertical position of the pointer 150 and detects that the position is in the second stage position (relative distance) from the reference position (first stage). Then, the change amount Hw = 1/2 in the second stage is read from the regulation information storage unit 63b, and the zone position corresponding to the detected movement amount (in this case, since the movement in the horizontal axis direction is not performed, the zone position Is sent to the zone marker generating unit 64 and the peak marker generating unit 61b. The zone marker generating unit 64 sets the zone width by multiplying the default zone width by the change amount Hw = 1/2, and leaves the zone position (position [2] in FIG. 15) as it is. The peak marker generation unit 61b reads the waveform data of the measurement waveform 100 within a time width corresponding to ½ of the default zone width from the measurement data storage unit 61a, and the maximum value from the read waveform data. And a peak marker 180 is added to the position for display (marked with ▽ in FIG. 16).

  Further, as shown in FIG. 16, the operator moves the position of the pointer 150 on the horizontal axis to move it from the position of the zone position [3] (same as [2]) to the position of [4], and the zone width. It moves so that the target point 130 may enter. In this case, similarly to FIG. 5, the second stage change amount Hw = 1/2 is maintained. By doing so, the peak marker generating unit 61b converts the waveform data of the measurement waveform 100 within the time width corresponding to ½ of the default zone width at the new zone position (position [4] in FIG. 16) into the measurement data. Reading from the storage unit 61a, a waveform position indicating the maximum value is obtained from the read waveform data, and a peak marker 180 is added to the position and displayed (marked with ▽ in FIG. 17).

  With the above configuration, the zone marker 170 can be moved while being smoothly changed, so that the peak point near the target point 130 can be smoothly separated and the zone marker 170 can capture the target point 130.

  In the third embodiment, the change amount Hw is shown as a magnification that is a relative value to the default value, but may be an absolute value. If the magnification is 5 levels, Hw = 1/1, 1/2,..., 1/6, for absolute values, the measurement time width (display time width) on the horizontal axis Regardless, if the physical display point on the horizontal axis is N points, for example, the first stage width Hws = N / 10, the second stage width Hws = N / 20,... What is necessary is just to memorize | store in the prescription | regulation information memory | storage part 63b as it is called the width Hws = N / 60 of the step.

[Fourth Embodiment]
A fourth embodiment will be described with reference to FIG. In FIG. 13, the main parts denoted by the same reference numerals as those in FIGS. 1, 9, and 12 have the same functions.

  In the fourth embodiment, the display unit 41 of the user IF unit 40 in FIG. 13 is changed to a normal display unit that is not a touch panel in the third embodiment. Accordingly, the pointer 150 has been described as a finger in the third embodiment, but the pointer marker 150a serving as a marker that replaces the finger can be operated from the operation unit 42. That is, the pointer marker generation unit 67 in the display control unit 60A of FIG. 13 receives information indicating the operation amount and direction by the operator from an encoder or the like (for example, a mouse) from the operation unit 42, and follows the information. The pointer marker 150a is generated in the moving direction and position and displayed on the display unit 42, and the moving direction and position of the pointer marker 150a are notified to the position detecting unit 63a. Since other operations are the same as those in the third embodiment, the description thereof is omitted.

[Fifth Embodiment]
A fifth embodiment will be described with reference to FIG. In FIG. 18, the main parts denoted by the same reference numerals as those in FIGS. 1, 9, 12, and 13 have the same functions. The fifth embodiment will also be described with an example in which the horizontal axis is time and the vertical axis is level.

  In the third embodiment, the indication resolution for the measurement waveform 100 is changed by changing the width of the zone marker 170 in accordance with the vertical position of the pointer 150, whereas in the fifth embodiment, the zone marker 170 is changed. By changing the display range when displaying the measurement waveform 100 while keeping the width of the constant width (also referred to as “display time range”), the indication resolution for the measurement waveform 100 of the zone marker 170 is changed, The target point 130 is easily captured by the peak marker 180. Therefore, the third embodiment and the fifth embodiment have the same idea relatively and effectively, although the objects to be controlled to improve the indication resolution are different.

  However, the measurement unit 30 obtains the number of time fine data on the horizontal axis so that it can correspond to the expansion / reduction of the display time width on the horizontal axis when displaying the measurement waveform 100 as described later, Assume that measurement data of the measurement waveform 100 is stored in the measurement data storage unit 61a. For example, it is assumed that the time width ΔT when the display time width is reduced to the minimum when the number of physical display points is L on the horizontal axis (in this case, the horizontal direction of the display image is enlarged) is displayed. In order to be able to expand the time width to the maximum Max times (reduction as an image), the number of data of L × Max or more is acquired with finer detail than (ΔT / L) ÷ Max. In the above example, if the display time width changes in six steps from 1/1 to 1/6, the time width of Max corresponds to the first step, and the time width at the time of minimum reduction corresponds to the sixth step.

  Moreover, the example which comprised the display part 11 with the touch panel is 5th Embodiment, and the example comprised by the normal display part is 6th Embodiment mentioned later.

  18, the difference from FIG. 12 will be mainly described below. The regulation information storage unit 65b in the span control unit 65 in the display control unit 60B in FIG. 18 displays in advance corresponding to the vertical axis position of the pointer 150 (finger) before shipment or measurement. Therefore, a time range (the display time width on the horizontal axis, also referred to as a span width) to be read from the measurement data storage unit 61a is stored. For example, the vertical axis position is divided into n stages from higher to lower, and a value (the direction in which the horizontal axis direction of the displayed image is enlarged) is stored that decreases as the position of the pointer 150 decreases. Keep it. As in the third embodiment, the display time width stored in the regulation information storage unit 65b may be defined by a display time width change amount Hw (magnification), or an absolute value (a physical axis on the horizontal axis). It may be defined by the number of display points). Here, the change amount Hw will be described. These are defined by the display time width, but may be defined by enlargement / reduction of the image. In this case, the change rate Hw is inversely related to the display time width, such that the first stage is 6 times, the second stage is twice, and the sixth stage is 1 time.

  The position detection unit 65a of the span control unit 65 in FIG. 18 has a difference that the display time width (span) is determined instead of the position detection unit 63a of the third embodiment determining the width of the zone marker 170. Other operations are the same. A brief description is given below. As shown in FIG. 15, the amount of movement in the width direction in the horizontal axis direction and the position in the vertical axis direction when the pointer 150 is operated on the screen of the display unit 11 of the touch panel are detected. For example, the amount of movement in the width direction and the vertical position of the finger (pointer) when the operator touches the touch panel on the screen with the finger and moves the touched position (the position of the pointer 150) are detected.

  Details are as follows. The position detector 65a detects whether or not the pointer 150 is first placed, and detects and stores the vertical axis position when the pointer 150 is first placed as a reference position. Then, any one of a plurality of stages n stored in the regulation information storage unit 65b is assigned to the reference position. For example, the first stage (change amount Hw = 1) is assigned to the reference position. Thereafter, the position detector 65a detects how much the pointer 150 has moved in the vertical axis direction from the reference position. That is, the relative distance is detected. Then, it is detected which of the plurality of stages n the relative distance corresponds to, and the change amount (ratio) Hw corresponding to that stage is read from the regulation information storage unit 65b and sent to the peak marker generation unit 61b. At this time, the position detection unit 65a also detects the amount of movement in the width direction of the pointer 150 in the horizontal axis direction, and sends it to the zone marker generation unit 64 and the peak marker generation unit 61b. For example, since the stage n of the relative distance YL when the pointer 150 in FIG. 21 is lowered from the position [2] to the position [3] in FIG. 22 is the third stage, the change at this stage (n = 3). Hw = 1/3 is read from the regulation information storage unit 65b as the amount Hw and sent to the zone marker generation unit 64 and the peak marker generation unit 61b. At this time, the position detector 65a also detects the amount of movement in the width direction of the pointer 150 in the horizontal axis direction and sends this amount of movement in the width direction together with the change amount Hw to the zone marker generator 64 and the peak marker generator 21b. .

  The zone marker generating unit 64 generates a vertically long rod-shaped zone marker 170 having a certain width, and displays it at the zone position (the center position of the zone marker 170) moved by the amount of movement in the width direction instructed from the position detecting unit 65a. . On the other hand, the Zo marker generating unit 64 sends information of a certain width to the peak marker generating unit 61b.

  The data display control unit 61 is centered on the time position corresponding to the zone position detected by the position detection unit 65a, and the horizontal axis is the change amount Hw received from the position detection unit 65a based on the default display time width. The display time width is changed to the corresponding display time, and the coordinate having the vertical axis as the size of the measurement waveform 100 and the measurement waveform 100 stored in the measurement data storage unit 61a are displayed on the display unit 11. The latest zone marker 170 generated by the zone marker generating unit 64 is displayed on the measurement waveform 100 displayed on the display unit 11. For example, when the change amount Hw = 1/1 to 1/6 as described above, the data display control unit 61 has a default width and a maximum display time when the change amount Hw = 1/1. Displayed with a width of 6 × ΔT (change amount Hw = 1/1 is 6 times the change amount Hw = 1/6), and when change amount Hw = 1/6, the display is performed with the minimum display time width ΔT.

  The peak marker generation unit 61b instructs from the zone marker generation unit 64 around the time position corresponding to the zone position corresponding to the movement amount detected by the position detection unit 65a from the measurement data storage unit 61a (center position of the zone marker 170). The data corresponding to the time range of the width of the zone marker 170 is read, the waveform position showing the maximum value within the zone width is searched, and the peak marker 180 is displayed at the searched waveform position on the display unit 11.

  Since the processing time from the movement of the pointer 150 (finger) to the display of the latest zone marker 170 and peak marker 180 after detecting the vertical position and width direction movement amount of the pointer 150 is short, the operator Can be observed without a sense of incongruity.

Next, a series of operations will be described based on FIGS.
In FIG. 20, the horizontal axis indicates the measurement time, and the vertical axis indicates the size of the measurement waveform 100. Here, the operation from the position of the zone marker 170 in FIG. 20 to setting to the target point 130 (◯ mark) to be measured will be described. In FIG. 20, the zone marker generation unit 64 displays a zone marker 170 having a constant zone width at a predetermined zone position as a default, and the peak marker generation unit 61b displays the data of the measurement waveform 100 within the zone position and the zone width. A description will be given assuming that the peak position is searched and the peak marker 180 at that position is displayed.

  In FIG. 20, the operator places the pointer 150 (finger) on the display surface and moves it toward the target point 130. At that time, the position detection unit 65a detects whether or not the pointer 150 is first placed, and the vertical position when it is first placed is set as a reference position (the vertical position of [1] in FIG. 20). Detect and memorize. Then, the first stage (change amount Hw = 1) of the plurality of stages n stored in the regulation information storage unit 65b is assigned to the reference position. Then, while the operator moves the pointer 150 (finger) from the position [1] in FIG. 20 toward the target point 130 in the horizontal axis direction, the first stage change amount Hw = 1/1 is defined. The information is read from the information storage unit 65b and sent to the zone marker generation unit 64 and the peak marker generation unit 61b together with the movement amount of the pointer 150 detected in the width direction at the same time.

  Since the change amount Hw = 1/1, the data display control unit 61 displays the measurement waveform 100 with the default time width. The zone marker generating unit 64 moves the zone marker 170 to a zone position (a position corresponding to [2] in FIG. 21) corresponding to the designated movement amount in the width direction with a default zone width. The peak marker generation unit 61b reads the waveform data of the measurement waveform 100 within the default time width at the position corresponding to the designated position (position [2] in FIG. 21) from the measurement data storage unit 61a. A waveform position showing the maximum value is obtained from the waveform data obtained, and a peak marker 180 is added to the position and displayed (marked with ▽ in FIG. 21).

  In FIG. 21, since the peak marker 180 has not yet reached the target point 130, it is necessary to further widen the display time width. Therefore, the operator lowers the pointer 150 in FIG. 21 from the position [2] to the position [3] in FIG. 22, that is, in the second stage (relative distance) in the vertical axis direction. Then, the position detection unit 65a detects the vertical position of the pointer 150 and detects that the position is in the second stage position (relative distance) from the reference position (first stage). Then, the second stage change amount Hw = 1/2 is read from the regulation information storage unit 65b, and the zone position corresponding to the detected width direction movement amount (in this case, the zone position in the horizontal axis direction is the same as [2]. )) To the zone marker generator 64 and the peak marker generator 61b. The data display control unit 61 displays the waveform of the measurement waveform 100 corresponding to the time width (1/2 times) obtained by multiplying the default time width (time width when Hw = 1/1) by the amount of change Hw = 1/2. Data is read from the measurement data storage unit 61a and displayed (see waveform in FIG. 22, time width on the horizontal axis). The zone marker generator 64 keeps the zone position (position [2] in FIG. 22) as it is. The peak marker generation unit 61b reads the waveform data of the measurement waveform 100 within a time width that is ½ times the default time width from the measurement data storage unit 61a, and outputs the maximum value from the read measurement waveform 100. Is obtained, and a peak marker 180 is added to the position for display (marked with ▽ in FIG. 22). In FIG. 22, a peak marker 180 is displayed at the target point 130, and a measured value at the peak waveform position is displayed as a numerical value on the right side of the screen.

  With the above configuration, the display range of the measurement waveform 100 can be moved while being smoothly changed. Therefore, the peak point near the target point 130 can be smoothly separated by relatively increasing the indication resolution of the zone marker 170. Thus, the target point 130 can be captured by the zone marker 170.

[Sixth Embodiment]
A sixth embodiment will be described with reference to FIG. In FIG. 19, the main part which attached | subjected the same code | symbol as FIG.1, FIG.9, FIG.12, FIG.13 and FIG.
