Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present proposal relates to a waveform analysis device, and more particularly to a device that allows a user to arbitrarily change the setting of the movement amount of a pointing device such as a cursor.

[0002]

[Prior Art]

 In the conventional waveform measuring device, various settings can be made using the panel keys, rotary knob, keyboard, etc. However, when a pointing device such as a cursor is moved on the screen as the rotary knob rotates, the amount of movement by turning the knob is read from a fixed memory in the device. (For example, with respect to one click of the knob, whether the cursor for one raster moves or for 100 rasters is read from the ROM written in advance.)

[0003]

[Problems to be solved by the device]

 For this reason, the amount of movement for one click cannot be set for the convenience of the user in use, resulting in poor operability. Also, when observing subtle waveforms, there may be omissions in observing waveform changes. The present invention is intended to solve the above problems, and realizes a waveform analyzer having a man-machine interface that allows a user to freely change the setting method when moving a pointing device.

[0004]

[Means for Solving the Problems]

 The present invention provides an analog / digital converter for converting an input signal into an analog / digital signal, a man-machine interface for inputting a one-dimensional change such as a rotary knob or a mouse from the outside, and a setting for the man-machine interface. A control means for outputting a control signal and data, a variable memory for storing the data from the control means and outputting a value in the calculation of the data, and a signal from the control means for controlling the value of the variable memory or the fixed memory. Inputting data from the analog / digital converter and selecting means to calculate waveform data, and inputting data from the waveform data calculating means. , A display circuit for converting into display data and a table for displaying the signal from the display circuit as a screen. Characterized in that a and vessels, a waveform analyzer that the user of one-dimensional variation can variably be Rukoto in man-machine interface.

[0005]

[Action]

 The movement amount setting is written in the RAM and the operation is usually set by the ROM. However, the user can arbitrarily change the movement amount setting of the pointing device by reading only the movement amount data from the RAM. I can do things.

【Example】

 FIG. 1 is a basic configuration diagram of the present invention.

In the figure, reference numeral 1 denotes an analog / digital conversion means (hereinafter referred to as A / D conversion means), which performs analog / digital conversion on an input signal. Reference numeral 2 is a control means for inputting a signal from the man-machine interface 3, selecting a signal by the selecting means 5 and outputting write data to the variable memory 6. The man-machine interface 3 is an external setting means such as a rotary knob or a keyboard. Specifically, it is means for moving the pointing device, inputting settings, etc., and a signal from this means is read by the control means 2. Reference numeral 4 is a waveform data calculation means for calculating the data from the A / D conversion means 1 and inputting a signal from the selection means 5. The selection means 5 outputs the data of the variable memory 6 or the fixed memory 7 in response to a signal from the control means 2. Data is stored in the variable memory 6 by a signal from the control means 2. A control program or the like is written in the fixed memory 7 in advance. A display circuit 8 converts the output from the waveform data calculation means 4 into a signal for display. Reference numeral 9 is a display device which displays based on the signal from the display circuit 8.

The operation of the configuration in FIG. 1 will be described by giving a specific example. FIG. 2 shows a concrete embodiment of the present invention. In the figure, the same parts as those in FIG. ADC 1 is an A / D converter, and specifically shows A / D conversion means. The CPU 2 is also a specific example of the control means 2. The rotary knob 31 and the keyboard 32 constitute the man-machine interface 3. The waveform data processor 4 (hereinafter referred to as the waveform DSP) is a concrete embodiment of the waveform data calculation means 4. The RAM 6 is a variable memory 6 and the ROM 7 is a fixed memory. The display circuit 8 is composed of a display DSP (a so-called display processor) 81 and a CRTC (a so-called CRT controller) 82. The CRT 9 is a concrete example of the display 9.

The operation will be described below. By executing the program stored in the ROM 7, the CPU 2 controls the display DSP 81 and the CRTC 82 controller to display the menu on the screen of the CRT 9. Use this menu to set the movement amount of the pointing device. This setting input is performed by operating the knob 31 or the keyboard 32. In the case of the knob 31, its rotation angle is detected, and a number proportional to the rotated angle is recorded in the CPU 2 as a count value. Based on the count value stored here and the fixed change amount of the contents stored in the ROM 7, the relationship set value between the rotation of the knob 31 as the means for moving the cursor and the moving amount of the cursor is determined. To do. The determined value is output to the waveform DSP 4, the data is converted to be displayed on the display DSP 81, and the converted data is displayed on the CRT 9.

According to the series of procedures described above, the relation set value between the rotation of the knob 31 and the movement amount of the cursor (hereinafter, referred to as the knob 31 depending on the program stored in the ROM 7, the change amount of the knob 31 and the rotation angle of the knob 31). Change amount) is determined. The setting value determines the operation of the knob 31 and the movement amount of the pointing device. The value set by the user is stored in the RAM 6 and can be used by selection.

A specific case will be described. The amount of change of the knob 31 has two optimum values, roughly or finely (hereinafter referred to as COARSE / FINE), for each setting item such as setting of movement of waveform. This optimum value is stored in the ROM 7 in advance as a default value. However, there are cases where the amount of cursor movement cannot be dealt with only by using the default COARSE / FINE values. For example, there is a case where the position of the trigger delay is changed by rotating the knob 31 on the waveform display. This is because in recent waveform observing devices such as digital oscilloscopes, the waveform data to be stored and stored tends to increase, which requires moving the cursor by many screens. In such a case, the present invention realizes that the user can freely change the relationship between the rotation and the movement amount of the knob 31. If the user wants to set many types of movement amount other than the above, it is also possible to set the two stages of COAR SE / FINE to three stages, etc., and switch these stages to set the movement amount. By backing up the RAM 6 with a battery, it is possible to store the data when the power is off.

[Effect of the device]

 As described in detail above, the present invention enables the user to set the amount of change of the knob in the waveform analyzer.
