[0002]

2. Description of the Related Art The prior art will be described below with reference to the structure and functional block diagram example of the data knob 21 of FIG. 3A, the spectrum analyzer display screen and various switches of FIG. 3B. Explained. With this configuration, the rotation pulse signal 24a from the rotary encoder 24 is given to the pulse conversion unit 54 by the rotation of the data knob 21. The function mode register 53 forms and outputs a function mode signal 53a for controlling the rotation pulse signal 24a to be converted into N times the number of pulses by the pulse converter according to the function condition. The pulse conversion unit 54 includes the function mode register 53.
Receiving the function mode signal 53a from the conversion pulse signal 55 to convert the rotation pulse signal 24a into N times the number of pulses.
Is being output. Then, this converted pulse signal 55 is
It supplies to each control part 58a-58e. On the other hand, various key switches for changing the operation function are assigned individual key switches on the operation panel 31 as shown in FIG. 3B, and a predetermined key switch is selected for each function from the key switch group. The switch signal 17 obtained by selecting and pressing the key switch is given to each of the control units 58a to 58e and the function mode register 53.

According to this, when the data knob 21 is operated while observing the spectrum waveform display screen 30 on the screen, an individual key switch is operated each time the operating function of the data knob 21 is changed. There is a need. Moreover, each time these key switches are operated, the line of sight is removed from the screen, the line of sight is changed in the direction of the key switch, the target key switch is found among the many key switch groups, and the target key switch is pressed. It is necessary to check on the screen and display lamps, and then return the hand to the data knob 21 and turn it. For this reason, the key switch to be pressed may be wrong, and the frequency of eye movements may increase, resulting in an ergonomically unfavorable operating procedure.

Next, this will be described below by showing four specific examples. Various key switches used in the following description are provided on the operation panel 31 shown in FIG.
Mainly divided into three types. These are the independent key 32, the soft key 34, and the ten-key 33. In this type, function switching is mainly placed on the independent key 32, such as a zoom function key, a cross cursor setting function key, a reference level value function key, a center frequency setting mode function key, etc. Is. The soft keys 34 are a plurality of keys that are mainly used after the above-mentioned function settings, and the functions can be arbitrarily changed by software control. The soft key 34 has a key function depending on the use state, such as a start key, a stop key, a next key, a decision key, an execution key, a repeat key, a span frequency key, and other switch functions required for each measurement function. Is a key that can be assigned and is arbitrarily defined and used.

In the first example, as shown in FIG.
When two frequencies of the spectrum waveform on the screen are designated and zoom display is performed between them, it is necessary to designate two points with the data knob 21. First operation panel 31
Press the Zoom function key on the top → press the start key to display the first marker on the screen → turn the data knob 21 to move the first marker on the screen to one of the first frequency positions → the stop key Press to confirm and the next 2nd marker will appear on the screen →
The zoom screen is displayed by the operation procedure of turning 1 to move the second marker to the other second frequency position on the screen and pressing the enter key to confirm.

In the second example, as shown in FIG.
Designate X on the screen with a cross cursor appearing on the screen
In the case of moving to the Y coordinate position and setting the designated XY position, it is also necessary to designate two points in the XY direction with the data knob 21. First, press the cross cursor setting function key on the operation panel 31 to declare the setting start from the X direction → rotate the data knob 21 in the X direction to determine the X axis position → press the NEXT key to switch to the Y direction setting mode → The setting is completed by the operation procedure of turning the data knob 21 to determine the Y-axis position and pressing the enter key.

In the third example, as shown in FIG.
When it is desired to continuously move the reference level value of the spectrum, that is, the sensitivity level of the input signal on the vertical axis to the upper limit and move the screen up and down to a position where it is easy to see, it is necessary to specify one point with the data knob 21. If the item for changing the step value of the scale is also performed at the same time as shown in FIG. 4D, it is necessary to specify two points. In the case of these two points,
First, in the vertical screen direction, for example, in the case of an operation of changing the screen display state in which the reference level value at the top of the screen is 0 dbm and the scale is 10 db step display, the reference level value is set to -30 dbm and the scale is changed to 2 db step display. First, press the reference level value function key on the operation panel 31 → press the start key → turn the data knob 21 to 0
Set from dbm to -30dbm → press the Next key to switch the mode to change the scale step value → turn the data knob 21 to change the display scale to 2db step display →
Setting is completed and the target screen is displayed by the operation procedure of pressing the execute key.

In the fourth example, the spectrum is displayed in such a manner that the center frequency and the span frequency, that is, the center frequency is always in the center of the screen when the display frequency range is determined. Therefore, as shown in FIG. 4 (f), when it is desired to change the center frequency to a screen position where it is easy to see or the span frequency at the same time, one or two points are designated by the data knob 21. There is a need. For example, when the center frequency setting mode / function key on the operation panel 31 is first pressed and the data knob 21 is turned to change the setting of the center frequency, the horizontal axis screen, that is, the frequency axis screen is moved each time the data knob 21 is rotated. After that, if it is not necessary to change the span frequency, press the enter key here. Otherwise →
Press the span frequency key to switch and set the span frequency mode → turn the data knob 21 to enlarge or reduce the frequency range of the screen each time the span frequency is changed. While watching this screen, press the Enter key to fix the screen by the operating procedure. If it is difficult to see on this screen, press any of the above keys and repeat the process.

[0009]

As described above, the key switches on the operation panel 31 are often operated while looking at the screen, so that the line of sight is moved from the screen to the key switch group. Moreover, since it is necessary to move the operating hand between the data knob 21 and the key switch, there are many cases in which the operability is difficult. In this way, when it is desired to switch between various functions of the data knob 21 while looking at the screen, the key switch to be pressed may be wrong, or the ergonomically increased frequency of eye movements. However, the operating procedure was unfavorable.

Therefore, the problem to be solved by the present invention is to improve the operability by minimizing the movement of the line of sight for the key operation and the movement of the operating hand when the key switch is frequently operated while looking at the screen. The purpose is to improve.

【Example】

(Embodiment 1) Regarding the embodiment of the present invention, the structure and functional block diagram of the data knob with a push button in FIG. 1 and FIG.
This will be described below with reference to spectrum waveform examples on the screens (a) to (f). The structure and functional block diagram of the data knob with a push button according to the present invention will be described with reference to FIG. The structure of the data knob 21 with a push button is the data knob 21.
The rotary encoder 24 and the push button switch 12 are provided, and the push button switch mechanism is added to the conventional data knob 21.

The data knob 21 has a mechanism that rotates to the left and right and a mechanism that can be pushed in the axial direction 21c of the data knob 21. A round recess 21a is provided at one corner of the knob of the data knob 21 so that even one finger can easily rotate it and simultaneously press a button. Therefore, both the rotating operation of the data knob 21 and the push button can be easily operated with one hand or a finger. Further, the rotation of the data knob 21 is a mechanism that gives a light click feeling for each unit pitch angle, and the data knob 21 does not need to be visually checked.

Next, when the data knob 21 is pressed, it is transmitted to the push button switch 12 via the central shaft, thereby opening and closing the contact of the switch. This switch is a momentary type push button, and the switch is ON while it is being pushed. In addition, the push button gives a light click feeling so that the user can feel the changed state of whether the button is pressed or not.

The rotary encoder 24 outputs a rotation pulse signal 24a by outputting one pulse signal for each unit pitch angle as in the conventional case. The data knob 21 with a push button is constructed by such a structure.

The configuration of the present invention comprises the data knob 21 with a push button, the switch state storage section 12b, the function mode register 13, the pulse conversion section 14, the conversion pulse signal 15, and the function conversion signal 16. I am configuring. On the other hand, a plurality of control units (18a to 1) for receiving these signals.
8e), and the basic operation is the same as the conventional one.

The switch state storage section 12b receives the switch signal 12a from the push button switch 12 and outputs a switch state signal 12c to the pulse conversion section 14. As the switch state signal 12c, firstly, it is output whether or not the current switch signal is in the ON state. Secondly, the number of times the switch signal is pressed is counted, and thus the number of times of switching to the binary state or the K value state higher than that is output. Thirdly, the push button is 2 in a short time.
It is judged whether or not the button is pressed once, and a so-called double-click state signal is output. These status values are functional mode
The register 13 is cleared and initialized by the contents of the newly changed condition. Then, if necessary, by defining and using these three types of switch states, the function is assigned to each measurement function, and various key switch replacements are realized.

The function mode register 13 changes when the function switch mainly corresponding to the switching function of the measurement function of the panel switch group or another key switch similar to this is pressed, and the function mode signal 13a is output. It outputs to the pulse conversion unit 14. For example, as in the conventional description, 2 of the spectrum waveform on the screen
When trying to zoom between frequencies, when a cross cursor appears on the screen to move to a specified XY coordinate position on the screen for setting, and the reference level value of the spectrum, that is, the input signal on the vertical axis. When the sensitivity level is continuously moved to the upper limit of the screen, or when the spectrum is displayed, the center frequency and the span frequency, that is, the display frequency range is determined.

The pulse conversion unit 14 receives the switch state signal 12c from the switch state storage unit 12b and the function mode signal 13a from the function mode register 13 and supplies the function conversion signals to the respective control units 18a to 18e. 16
Is output. The function conversion signal 16 is the control unit 18
It gives a selection signal of which control unit of a to 18e is to be activated, and an instruction of what operation of the control unit the converted pulse signal 15 is to be used for. In addition, these signals and the rotary encoder 24
In response to the rotation pulse signal 24a from the above, the conversion pulse signal 15 which has been converted to 1 times or N times or 1 / N is output as it is to speed up / down the cursor movement or coarse / fine shift of the screen. It also gives a function to do.

Next, an example in which various functions are assigned to the push button switch 12 will be concretely shown and described in comparison with the conventional example. In the first example, as shown in FIG. 4A, it is necessary to specify two frequencies of the spectrum waveform on the screen, and to specify two points with the data knob 21 in the case of zoom display between them. is there. In the operation procedure according to the present invention, first, when the zoom function key on the operation panel 31 is pressed, and the push button switch 12 is pressed, the first marker is displayed on the screen.
Turn 1 to move the first marker on the screen to one of the first frequency positions → press the push button switch 12 again to confirm, and the next second marker will appear on the screen → turn the data knob 21 Move the second marker to the other second frequency position on the screen → push button switch 1 again
The zoom screen is displayed by the operation procedure of pressing 2 to confirm. If a further zoom display is desired, the push button switch 12 is pressed again to act as a repeat key, and the same operation can be started from the movement of the first marker described above. In this case, pushbutton switch 12
However, it has a role of a start key, a stop key, an execution key, and a repeat key in addition to this, and these operations can be continuously performed without moving the eyes from the screen.

In the second example, as shown in FIG.
Designate X on the screen with a cross cursor appearing on the screen
In the case of moving to the Y coordinate position and setting the designated XY position, it is also necessary to designate two points in the XY direction with the data knob 21. First, press the cross cursor setting function key on the operation panel 31 to declare the setting start from the X direction → rotate the data knob 21 in the X direction to determine the X axis position → press the push button switch 12 to set the Y direction mode Setting is completed by operating the data knob 21 to determine the Y-axis position and pressing the push button switch 12 again. When it is desired to change the cross cursor again, pressing the push button switch 12 again serves as a repeat key, and the same operation can be started from the X direction at the beginning of the above description. When double-clicked, it works as a jump function key and can be started in the same way from the start of setting in the Y direction. Further, when the data knob 21 is rotated while the push button switch 12 is being pressed while the data knob 21 is being rotated, the cursor can be moved at 10 times the speed, and the cursor can be easily moved. Even in this case, the push button switch 12 is the next key,
These functions as the enter key, the repeat key in addition to the jump key, and the jump function key. Also, when the data knob 21 is turned while the push button switch 12 is being pressed, it has the role of a 10x speed key. However, these operations can be performed continuously without moving the eyes from the screen.

In the third example, as shown in FIG.
When it is desired to continuously move the spectrum level value, that is, the sensitivity level of the input signal on the vertical axis to the upper limit of the screen to move the screen up and down to a position easy to see, one point is set to the data knob 21.
However, if an item for changing the step value of the scale is also performed at the same time as shown in FIG. 4D, it is necessary to specify two points. In the case of these two points, first, in the vertical screen direction, for example, the reference level value at the top of the screen is 0d.
At the screen display state where the scale was 10 dB step display at the bm position, set the reference level value to -30 dbm and set the scale to 2
The operation to change to the db step display is the operation panel 3 first.
1 Press the reference level value function key above → press the push button switch 12 → turn the data knob 21 to 0
Set from dbm to -30dbm → press push button switch 12 again to switch the scale step value to change mode → turn data knob 21 to change the display scale to 2db step display → press push button switch 12 again The setting is completed by the procedure and the target screen is displayed. If it is difficult to see at this screen position, press the push button again.
If the switch 12 is pressed, it can be similarly started from the change of the reference level value at the beginning of the above description. In this case, the push button switch 12 has a start key, a next key,
It has a role of an execution key and a repetition key, and these operations can be continuously performed without moving the eyes from the screen.

In the fourth example, the spectrum is displayed in such a manner that the center frequency is always in the center of the screen when the center frequency and the span frequency, that is, the display frequency range is determined. Therefore, as shown in FIG. 4 (f), when it is desired to change the center frequency to a screen position where it is easy to see or the span frequency at the same time, one or two points are designated by the data knob 21. There is a need. For example, when the center frequency setting mode / function key on the operation panel 31 is first pressed and the data knob 21 is rotated to change the setting of the center frequency, the screen moves with the frequency as the horizontal axis each time the data knob 21 rotates. After that, the push button switch 12 is pushed whether or not the span frequency needs to be changed. If it is not necessary to change the span frequency, the push button switch 12 is continuously pressed to complete the operation. Otherwise, the current state has been switched to frequency mode. → Data knob 21
Turn to change the span frequency setting and expand or reduce the frequency range of the screen each time. While watching this screen, the screen is fixed by the operation procedure of pressing the push button switch 12 again. If it is difficult to see on this screen, by pressing the push button switch 12 again, the first center frequency described above can be similarly started from the setting change. Further, in the case of this function, if the data knob 21 is turned while the push button switch 12 is still pressed, the span frequency range can be expanded / reduced, and the push button switch 12 can be fixed when it is returned. Can be operated. Even in this case, the push button switch 12 functions as a span frequency key, an enter key, and other repeat keys. Also, as a new function, if the data knob 21 is turned while the push button switch 12 is still pressed, it has the role of allowing the span frequency range to be enlarged or reduced, and these operations can be performed without moving the eyes from the screen. , Can be operated continuously.

As described in the above example of use, the pushbutton switch 12 can be used by defining the functions of a plurality of keyswitches for setting the specifications for each function in the switch of the pushbutton-equipped data knob 21. Alternatively, when the data knob 21 is rotated while the push button switch 12 is kept pressed, the data knob 21 functions as a data knob 21 having another function, or the rotation pulse signal 24a.
Pulse conversion section by giving a function means to switch between N times output and switching, and when double-clicking, functioning as a key to jump over the next specification setting key switch function. This is realized by switching to various easy-to-use key definitions according to the measurement status of each function at 14.

(Embodiment 2) An embodiment of the present invention will be described below with reference to a configuration example in which a function mode signal is directly given to each control unit in the structure and functional block diagram of the data knob with a push button in FIG. To do. In the above description of the first embodiment, the functional mode register 13 is provided and the functional conversion signal 16 is output by this, but as shown in FIG. 2, the functional mode signal 13a is sent to the pulse converter 14. Give,
In addition, the configuration is such that the control units 18a to 18e are directly provided,
The function conversion signal 16 is deleted. In this way, the respective control units 18a to 18e may be directly controlled to switch the operation and similarly performed.

Although the push button switch 12 is connected to the data knob 21 in the above description, it may be an independent push button switch 12.
For example, the right hand may operate the data knob 21 and the left hand may operate the push button switch 12. Further, even if the push button / switch 12 is operated with a foot, the same operation can be performed without keeping an eye on the screen.

[0029]

Since the present invention is configured as described above, it has the following effects. By assigning a function to the push button switch 12 for each function of the function mode register 13, most of the plurality of key functions can be easily replaced only by the push button switch 12, so that the eyes of the display screen can be seen. The frequency of separation can be reduced as much as possible. Therefore, the desired operation can be performed without taking the eye off the spectrum display screen, and the operability is extremely improved ergonomically. Therefore, the user's operation mistake and troublesomeness are eliminated, the operability is improved, and it becomes easier to use. As a result, the effect of further improving the convenience of the user can be obtained. By assigning a function to the push button switch 12 for each function of the function mode register 13, most of the plurality of key functions can be easily replaced with only the push button switch 12, so that other key switches can be replaced. The effect of reduction can be obtained. Further, when the data knob 21 is rotated while the push button switch 12 is being pressed while the data knob 21 is being rotated, N times or 1
Since the / N times rotation pulse signal can be given to each of the control units 18a to 18e, the cursor can be moved at high speed / low speed, and the screen can be roughly / finely moved. To be Further, even when a plurality of keys are defined, if the jump function of double-clicking the push button switch 12 is defined, it is possible to easily execute the next defined key by jumping. The effect of further improving convenience can be obtained.
