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.

  In order to achieve the above object, in the present invention, the marker position in the marker operation direction for moving the waveform marker is associated with the magnitude of the marker movement change amount. As an example, if a marker operation is performed at the top of the display screen that displays the measured waveform, the waveform marker is displayed at approximately the same speed (same distance) as the amount of marker operation. If the marker operation is performed at the bottom of the display screen, the waveform marker follows at a slow speed (small distance) with respect to the operation amount of the marker operation. It was set as the structure which enables a fine adjustment by moving. That is, for example, by moving the marker operation position up and down along the index displayed in the display screen, the movement change amount of the waveform marker in response to the marker operation can be changed, and the direction in which you want to move the waveform marker in the display screen By operating the marker in the horizontal direction (in this case), the waveform marker can be moved. Accordingly, it is possible to perform coarse adjustment and fine adjustment continuously by only the marker operation on the display screen on which the measurement waveform is displayed, that is, by a single operation.

  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.

  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 that makes it easy to separate a plurality of peaks with a peak marker, measurement data (measurement waveform measured by the measurement unit 30) is displayed in the third and fourth embodiments in an example in which the zone width is changed. Examples of changing the display range, which is a range, will be described in the fifth and sixth embodiments.

[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. It is applicable to measurement fields such as shape measurement, flow rate measurement, medical measurement, etc., in which a waveform marker is inserted therein to acquire image characteristics at the position of the waveform marker (for example, first to sixth Same as the 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 an index display control 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. 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.

  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 waveform data, that is, an area for displaying coordinates indicated by the horizontal axis-vertical axis, and so on). The amount of operation when the pointer 150 is operated, for example, when the operator touches the touch panel of the screen with a finger and moves the touched position, the amount of movement of the finger (pointer) (operation amount: below) , Simply saying “movement amount” indicates the movement distance.) And movement direction, or when the operator touches the touch panel with a pen or the like to move the touch position, the movement amount and movement direction of the pen or the like. Is 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 index storage unit 23c of the index display control unit 23 moves the waveform marker 110 that actually moves the waveform marker 110 relative to the amount of movement of the pointer 150 (hereinafter referred to as “waveform marker movement amount”). Are defined in a plurality of stages, 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. The index storage unit 2c stores a value for N of the movement amount ratio H (N) = (waveform marker movement amount) / (pointer movement amount) = k / N as the regulation information.

  The index generation unit 23b manages such that any one of the plurality of steps can be specified on the screen of the display unit 11. As one form, the index generation unit 23b uses a bar-like marker having a length in the vertical direction as shown in FIG. (Or, by pattern) A segmented index 120 is generated and displayed on the display unit 11. In the case of FIG. 2A, the horizontal axis position of the index 120 is the same as the horizontal axis position determined by the marker generation unit 21b, that is, the waveform marker 110. In FIG. 2A, the index 120 is divided into four areas (N = N1, N2, N3, N4), and the uppermost area of the index is the movement amount ratio H (N) = (waveform marker movement amount). / (Pointer movement amount) is close to 1, and as the index region decreases, the movement amount ratio H (N) decreases, and the lowest region has a minimum configuration.

  The index selection detection unit 23a detects which region of the index 120, that is, which stage is designated by the pointer 150 when the measurement waveform 100, the waveform marker 110, and the index 120 are displayed on the screen of the display unit 11. To do. Since the index selection detection unit 23a knows where the index generation unit 23b displays the index and how the area (stage) is divided and displayed, the index selection detection unit 23a determines the pointer from the position of the pointer 150 on the touch panel of the screen. The specific stage Ng selected at 150 can be determined. Then, the movement amount ratio H (Ng) corresponding to the selected specific stage Ng is read with reference to the index storage unit 23c and sent to the marker generation unit 21b.

  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 by selecting the specific stage Ng of the index 120, the specific amount determined and detected by the index selection detection unit 23a is received from the instruction amount detection unit 22 by the movement amount and movement direction of the pointer 150. The waveform marker movement amount is obtained based on the movement amount ratio H (Ng) with respect to the stage Ng. That is, the horizontal position of the waveform marker is determined as waveform marker movement amount = H (Ng) × (movement amount of 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. A waveform marker is displayed at the vertical axis position indicated by the size of.

  The above-described series of operations “movement of the pointer 150—detection of the amount of movement of the pointer 150 by the instruction amount detection unit 22—detection of the index 120 by the index selection detection unit 23a and determination of a specific stage—the waveform marker 110 by the marker generation unit 21b The “position determination and display thereof” 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. Accordingly, there is no time difference between the movement of the pointer 150 and the movement of the waveform marker 110 although the movement amount (distance) is different.

  Accordingly, if the way of viewing is changed, the movement amount (distance) of the pointer 150 is large and the movement amount (distance) of the waveform marker is small at the same time. It can be said that the marker generation unit 21b determines 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. Accordingly, the movement amount ratio 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.

  A series of operations and the actual movement of the waveform marker 110 according to the first embodiment will be described with reference to FIGS. 8 and 2 to 4.

Step S1: In the state where the switch for setting the waveform marker 110 is turned on (Marker on), the measurement waveform 100 measured by the measurement unit 30 and the index generated by the index generation unit 23b are displayed on the display unit 11 of the touch panel structure. 120 is generated and displayed at a predetermined initial position. As shown in FIG. 2A, the indicator 120 has a rod shape, and is divided into areas in four stages in the length direction by color (pattern). On the other hand, the index storage unit 23c sets the four-stage movement amount ratio H (N) in advance according to the stages N1, N2, N3, and N4 (N1 <N2 <N3 <N4). As H1>H2>H3> H4), the data are stored corresponding to the areas divided for each stage.
Step S2: The marker generator 21b displays the waveform marker 110 at the same position as the initial position of the index 120.

  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 moves the pointer (finger) 150 in the direction of the target point 130 with the pointer (finger) 150 placed on the top of the bar-shaped index 120.
Step S4: The index selection detection unit 23a detects that the position of the pointer 150 is the uppermost region (N1), and sends the movement amount ratio H1 corresponding to the uppermost region from the index storage unit 23c to the marker generation unit 21b. send.
Step S5: The instruction amount detection unit 22 detects the amount and direction of movement of the pointer 150 and notifies the marker generation unit 21b.
Step S6: The marker generation unit 21b determines a movement amount of (movement amount ratio H1) × (movement amount of the pointer). Then, the magnitude Y1 of the measurement waveform 100 at the position X1 obtained by shifting the distance (movement amount ratio H1) × (movement amount of the pointer) to the current position of the waveform marker 110 in the movement direction of the pointer 150 is the measurement data storage unit 21a. Read from.
Step S7: The marker generator 21b displays the waveform marker 110 at the coordinate position (X1, Y1) (updates the previous display position). In addition, the index generation unit 23b moves and displays the index 120 to the position of the waveform marker 110.

  The operations in steps S2 and S4 to S7 are performed in a predetermined fast processing cycle while the pointer 150 is moving 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.

  For example, as a result of moving the pointer 150 in FIG. 2A, when the waveform marker 110 is displayed at a position past the target point as shown in FIG. As shown in 3 (A), the index 120 is moved to the second stage (N2) from the top and moved to the target point side. Then, the waveform marker 110 and the index 120 move as (movement amount ratio H2) × (movement amount of the pointer) as shown in FIG. It becomes easier to adjust compared to the movement amount ratio H1. Further, when fine adjustment is desired, the pointer 150 is moved in a state where it is positioned at the lowest position (N4) as shown in FIG. 4A, and is adjusted to the target point 130 as shown in FIG. 4B. it can.

[Specific Mode for Specifying Each Stage of Indicator 120 Based on Guideline 150]
This has the following aspects (1) and (2).
(1) Aspect 1; When the pointer 150 is placed first in the index 120 specifying stage (specific area), until the next time the pointer 150 is specified in another specific stage (other specific area), Even if the pointer 150 moves away from the index 120, the movement amount ratio H corresponding to the specific stage of the previously placed position is set. Then, it is updated to the movement amount ratio H corresponding to another specific stage when placed in another specific stage (another specific area). Actually, such an operation can be handled by the detection by the index selection detection unit 23a.

If the movement amount ratio H1 = 1 when the pointer 150 is moved in step S3 described above, the waveform marker 110 and the index 120 seem to be almost simultaneously with the movement of the pointer 150 (step S2, step S4). ~ A delay corresponding to the loop operation in step S7 occurs.) Since the movement follows, it seems that these three move in almost the same position. However, when the movement amount ratio H1 <1, the movement amount of the pointer 150 is larger than the movement amount of the waveform marker 110 and the index 120, and thus the pointer 150 moves away from the waveform marker 110 and the index 120 ( (See FIG. 3B). Therefore, if it is the aspect 1, even if the pointer | guide 150 leaves | separates from the parameter | index 120, it can be made to move by the movement amount ratio H determined previously.
(2) Aspect 2: The screen area where the measurement waveform 100 is displayed is divided into bar-shaped indices 120, for example, divided into four areas representing four stages and areas parallel to each other, and the bar-shaped indices 120 Is used as a guide for each area. A typical display example is shown in FIG. The index 120 in this case is arranged as a guideline, and the effective index is an area divided by a dividing line 160 (horizontal dotted line) on the screen. In addition, the aspect which identified and displayed each area | region in the division line 160 of FIG. 5 with a color or a pattern is an aspect shown in FIG.

  5 and 6, the index 120 is displayed so as to be visually recognizable, but it is not necessarily required to be visible. When the pointer 150 is moved in a specific area of the screen, then the area is lowered and changed as shown in FIG. 4A, and the waveform marker 110 is moved in the direction to be moved as shown in FIG. 4B. This is because the operator can immediately recognize that the amount of movement of the waveform marker 110 is smaller than when the pointer 150 is moved in the previous area. At least, for example, it is only necessary that the operator can recognize that the movement amount ratio H is large at the top of the screen and the movement amount ratio H is small at the bottom.

Aspect 2 can also be practically handled by a configuration in which the index selection detection unit 23a manages the area of the screen for each magnitude of the movement amount ratio H and detects in which area the pointer 150 is present.
[Mode of Index 120]
(3) Direction of index 120 The above (1) and (2) can also be said to be aspects of the index 120. Incidentally, in each of the above cases, the index 120 is provided in parallel with the vertical axis of the coordinates of the screen of the display unit 11, and each stage (each region) of the index 120 is divided in the vertical axis direction.

[Second Embodiment]
Here, the first embodiment of FIG. 1 uses a touch panel, whereas the second embodiment of FIG. 9 is a case of using a normal display device having no sensor function on the screen. . 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 shown in FIG. 9 are partially different from the user I / F unit 10 and the display control unit 20 shown in FIG.

  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 generation unit 23d of the index display control unit 24 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 an encoder, and changes the pointer marker 150a according to the operation amount. Move.

  The instruction amount detection unit 22 in FIG. 9 receives and detects the operation amount of the operation unit 42 such as a mouse from the pointer marker generation unit 23d. When the amount of movement of the pointer marker 150a on the screen by the pointer marker generation unit 23d is the amount of movement of the pointer marker 150a as it is, the instruction amount detection unit 22 is not necessarily required (the instruction amount detection unit 22 of FIG. Reason for framed). Further, the index selection detection unit 23a of the display control unit 50 in FIG. 9 receives the position information of the pointer marker 150a that the pointer marker generation unit 23d has moved by the operation amount by the movement operation of the mouse or the like, and the pointer marker 150a The specific stage Ng designated by the pointer marker 150a can be specified from the position information and the position information of the index 120 generated by the index generation unit 23b, and the movement amount ratio H (Ng) can be determined.

  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. In addition, the aspect of said (1)-(5) is applicable similarly.

  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 show that the “pointer” in FIG. 8 is replaced with “pointer marker”, and the pointer marker 150a is displayed in step S2a, and the pointer marker 150a is displayed in step S3a according to the operation in step S3. It is different in that it moves. The operation of other steps in FIG. 11 is the same as that in FIG.

[Third Embodiment]
In the third embodiment, the index 120 in the first embodiment has a function as a zone marker 170 having a variable width, and the waveform marker 110 in the first embodiment is displayed at the peak point of the measurement waveform 100. A function as a peak marker 110a is provided.

  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. Then, the measurement waveform 100 stored in the measurement data storage unit 61a is displayed on the screen on the display unit 11 together with the coordinates of the horizontal axis and the vertical axis (see FIG. 14). The display unit 11 will be described as being configured with a touch panel. The marker operation (zone marker 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 width determining unit 63a described later. A zone marker 170 (hereinafter 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 width determination unit 63a (or from the zone marker generation unit 64), and calculates the time position and 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. And the peak marker 110a is produced | generated and displayed on the peak position of the measurement waveform 100 (refer the ▽ mark of 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.

  As shown in FIG. 14, the indication position detection unit 63 d of the index control unit 63 displays the screen of the display unit 11 of the touch panel (a display area for displaying waveform data, that is, an area for displaying coordinates indicated by the horizontal axis-vertical axis, Hereinafter, the same meaning is used.) The position in the moving direction when the pointer 150 is operated on the zone marker 170 (lateral position; hereinafter referred to as “zone position”) and the vertical position ( Hereinafter referred to as “vertical position”). For example, the horizontal position and the vertical position of the finger (pointer) 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.

  The index storage unit 63c stores a zone width corresponding to the vertical position of the pointer 150 in advance before shipment or measurement. For example, the vertical position is divided into five levels from higher to lower, and the value that the zone width becomes narrower as the position of the pointer 150 is lowered is stored (not limited to five levels, but may be continuous). In addition, the identification may be displayed step by step, and the zone width direction may be reversed. This is preliminarily received from the operation unit 12 and is stored in the index storage unit 63c by the index generation unit 63b.

  The width determining unit 63a receives the vertical position detected by the designated position detecting unit 63d, searches the index storage unit 63c for the zone width corresponding to the vertical position, and the searched zone width and the designated position detecting unit 63d The detected zone position is sent to the zone marker generator 64 and the peak marker generator 61b.

  By doing so, the zone marker generating unit 64 arranges the zone marker 170 having the zone width instructed from the width determining unit 63a on the display unit 11 at the instructed zone position as described above. On the other hand, the peak marker generating unit 61b obtains, from the measurement data storage unit 61a, waveform data within a time width corresponding to the instructed zone width around the time position determined by the zone position instructed from the width determining unit 63a. A waveform position indicating the maximum value is obtained from the read measurement data, and a peak marker 110a is added to the position for display.

  Note that the time from when the change instruction is made with the pointer 150 until the zone marker 170 and the peak marker 110a are displayed at the changed positions is processed at a high speed, so that the operator can set the zone width of the zone marker and the zone marker. You can change the zone position and know the result without any discomfort (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. In this state, the peak marker 110a is displayed at that position.

  In FIG. 14, the operator places the pointer 150 (finger) on the upper part of the zone marker 170 and moves it toward the target point 130. The indicated position detection unit 63d detects the movement position (zone position) of the pointer and also detects the vertical position of the pointer 150. The width determining unit 63a receives the vertical position detected by the designated position detecting unit 63d, searches the index storage unit 63c for the zone width corresponding to the vertical position, and the searched zone width and the designated position detecting unit 63d The detected zone position is instructed to the zone marker generating unit 64 and the peak marker generating unit 61b. Since the vertical position is not changed and the position of the pointer 150 is moved to the right side, the zone marker generating unit 64 moves the zone position by the same amount as the movement amount of the pointer 150 to the right side without changing the zone width. The peak marker generator 61b displays the peak marker 110a at the maximum waveform position of the measured waveform 100 within the zone width at the moved zone position. FIG. 15 is an example of this, and there are two peak positions including the target point 130 within the zone width, and the peak marker 110 a is displayed at the highest position outside the target higher than the target point 130. Therefore, the operator lowers the pointer 150 to a lower position on the zone marker 170. Then, the indicated position detection unit 63d reads the zone width (reduced zone width; effectively increases the indicated resolution) according to the changed position of the pointer 150 from the index storage unit 63c to generate the zone marker. Unit 64 and peak marker generation unit 61b. The zone marker generator 64 reduces and displays the zone width without changing the center position of the zone marker 170 in accordance with an instruction from the indicated position detector 63d. The peak marker generator 61b displays the peak marker 110a at the position of the maximum value of the measured waveform within the reduced zone width (see FIG. 16). Further, the operator moves the pointer 150 while keeping the pointer 150 at the lower position until the target point 130 enters the reduced zone marker 170. By doing so, the designated position detection unit 63d detects the zone position by the pointer 150 and instructs the zone marker generation unit 64 and the peak marker generation unit 61b. The zone marker generation unit 64 displays the zone marker 170 including the target point 130 without changing the zone width, and the peak marker generation unit 61b displays the position of the maximum value of the measurement waveform 100 within the zone width at the moved zone position, In this case, the peak marker 110a is displayed at the target point 130 (see FIG. 17).

  With the above-described 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 target point can be captured by the zone marker 170.

[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 I / F 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 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 indicates the pointer in the movement direction and position along the information. The marker 150a is generated and displayed on the display unit 41, and the moving position and position of the pointer marker 150a are notified to the indicated position detection unit 63d. 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.

  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 (also referred to as “display time range”) when displaying the measurement waveform 100 while keeping the width of the measurement area constant, the indication resolution for the measurement waveform 100 of the zone marker 170 is changed, and the target point 130 is easily captured by the peak marker 110a. 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, when the horizontal axis represents the number of physical display points as N, the time width ΔT at the time of reduction is displayed at the minimum, and (ΔT / N) ÷ Max in order to enable enlargement to the maximum Max times. The number of data of N × Max or more is acquired with finer details.

  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. In the index storage unit 63f in the index control unit 65 of FIG. 13, from the measurement data storage unit 61a to display in advance corresponding to the vertical position of the pointer 150 (finger) before shipment or measurement. The display range to be read (display time width corresponding to the horizontal axis) is stored. For example, the vertical position is divided into five levels from the highest to the lowest, and a value that shortens the display time width as the position of the pointer 150 decreases is stored. In response to the instruction from the operation unit 12, the index generation unit 63g stores the index storage unit 63f in advance. The display time width stored in the index storage unit 63f may be an absolute value or a magnification m (<Max).

  The width determination unit 63e receives the vertical position detected by the indicated position detection unit 63d, searches the index storage unit 63f for the display time width corresponding to the vertical position, and searches the displayed display time width and the specified position detection unit. The zone position detected by 63d is sent to the zone marker generation unit 64 and the measurement data storage unit 61a.

  The zone marker generating unit 64 generates a vertically long rod-shaped zone marker 170 having a certain width (which may be changed from the operation unit 12), and the zone position (zone marker) designated by the width determining unit 63e. At the center position). On the other hand, the zone marker generator 64 sends information of a certain width to the peak marker generator 61b.

  The data display control unit 61 uses the time range corresponding to the zone position detected by the indicated position detection unit 63d as the center, the time range on the horizontal axis as the display time width received from the width determination unit 63e, and the vertical axis as a measurement. The display unit 11 displays the coordinates of the waveform 100 and the measurement waveform 100 stored in the measurement data storage unit 61a. The latest zone marker generation unit 64 is displayed on the measurement waveform 100 displayed on the display unit 11. For example, as described above, the data display control unit 61 reduces the display point to the minimum under the condition that the number of display points on the horizontal axis is N, the time width ΔT at the time of reduced display, and the maximum expansion width Max times. The measured waveform data is acquired from the measurement data storage unit 61a every time interval (address interval) Max, and sequentially assigned to the display point N for display. At that time, when there is an instruction to change the display time width received from the width determining unit 63e to m times, measurement waveform data is acquired from the measurement data storage unit 61a at intervals of Max / m (address interval). The display points N are sequentially assigned and displayed. In addition, the display point corresponding to the time position corresponding to the zone position is assigned to the center and displayed.

  The peak marker generating unit 61b is a zone marker instructed from the zone marker generating unit 64 around the time position corresponding to the zone position detected by the indicated position detecting unit 63d from the measurement data storage unit 61a (center position of the zone marker 170). Data corresponding to a time range of 170 width is read out, the waveform position showing the maximum value is searched, and the peak marker 110 a is displayed at the searched waveform position on the display unit 11.

  Since the processing time from when the pointer 150 (finger) moves to when the vertical position and horizontal position (zone position) of the pointer 150 are detected and the latest zone marker 170 and peak marker 110a are displayed is short, The person can observe 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 110a at that position is displayed.

  In FIG. 20, the operator places the pointer 150 (finger) on the upper part of the zone marker 170 and moves it toward the target point 130. The indicated position detection unit 63d detects the movement position (zone position) of the pointer 150 and also detects the vertical position of the pointer 150. The width determination unit 63e receives the vertical position detected by the indicated position detection unit 63d, searches the index storage unit 63f for the display time width corresponding to the vertical position, and searches the displayed display time width and the specified position detection unit. The zone position detected by 63d is instructed to the zone marker generation unit 64 and the measurement data storage unit 61a (data display control unit 61). Since the vertical position is not changed and the position of the pointer 150 is moved to the right side, the zone marker generator 64 moves the zone position to the right by the same amount as the movement amount of the pointer 150. The peak marker generator 61b displays the peak marker 110a at the position of the maximum value of the measurement waveform 100 within the zone width at the moved zone position. FIG. 21 shows an example, and there are two peak positions including the target point 130 within the zone width, and among them, the peak marker 110a is displayed at the maximum position outside the target. Therefore, the operator lowers the pointer 150 to a lower position on the zone marker 170. Then, the indication position detection unit 63d detects the vertical position, and the width determination unit 63e reads the display time width corresponding to the changed vertical position of the pointer 150 from the index storage unit 63f, and the zone marker generation unit 64 and the measurement data. The data is sent to the storage unit 61a (data display control unit 61) to instruct display with a shortened display time width. The data display control unit 61 causes the display unit 11 to display the measurement waveform 100 together with the coordinates obtained by assigning the shortened display time width to the full scale of the horizontal axis. Therefore, the displayed measurement waveform 100 is displayed in an enlarged manner as compared to before the display time width is changed. FIG. 22 shows an example. In FIG. 22, the target point 130 is included in the zone width at this point. Since the width of the zone marker 170 remains constant, the indication resolution of the zone marker 170 with respect to the measurement waveform 100 is effectively improved. The peak marker generating unit 61b displays the peak marker 110a at the position of the maximum value of the measured waveform within the zone width of the zone marker 170, which is data of the measured waveform 100 within the shortened display time. In FIG. 22, the peak marker 110a is displayed at the target point 130, and the 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 changed smoothly. 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 and the peak marker 110a.

[Sixth Embodiment]
A sixth embodiment will be described with reference to FIG. In FIG. 19, the main parts denoted by the same reference numerals as those in FIGS. 1, 9, 12, 13, and 18 have the same functions.

Accordingly, the pointer 150 has been described as a finger in the fifth embodiment, but the pointer marker 150a as a marker that replaces the finger can be operated from the operation unit 42. That is, the pointer marker generation unit 67 in FIG. 19 receives information indicating the operation amount and direction by the operator from the encoder or the like from the operation unit 42, and generates the pointer marker 150a in the movement direction and position along the information. Are displayed on the display unit 41, and the moving direction and position of the pointer marker 150a are notified to the indicated position detection unit 63d.
