Abstract

PURPOSE:To obtain a display screen suitable for recording by a single key operation without accompanying any complicated key operation by producing a screen for recording automatically when a recording mode is selected. CONSTITUTION:When a recording key on a keyboard 12 is turned ON while an image for a display mode is shown on a CRT 6, a recording mode is set. Then, arithmetic control section 5 produces a graphic display data for a recording mode based on a data stored in a system memory 1 to be updated and stored into a graphic memory 3 while a character display data for the recording mode is produced to be updated and stored into a character memory 2. Based on the data thus updated and stored, an image for the recording mode is shown on the CRT 6 while a recording operation is executed with a printer 11. Upon the completion of the recording, the recording mode is released to be returned to a display mode.

Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to a waveform measuring device, and more particularly, to an improvement of a waveform measuring device having a function of recording a display screen.

<Prior Art> Waveform measurement devices such as digital oscilloscopes are often configured so that the display screen can be recorded using a built-in printer or a link or an external printer.

By the way, in such a screen recording function, the display screen is recorded as it is.

Specifically, if setting information areas B and C are displayed on the display section so as to overlap part of waveform display area A, as shown in Figure 3, this screen will be recorded as is. become.

However, in the recording result as shown in FIG. 3, a part of the waveform may be covered by the setting information areas B and C, and an important part of the waveform may not be recorded.

Therefore, in order to solve this inconvenience, the display of setting information areas B and C is erased from the screen by operating the operation panel, and only the waveform is displayed as shown in Figure 4. .

<Problems to be Solved by the Invention> However, according to such a method, when only waveform recording is desired, recording must be performed after performing key operations to obtain the desired screen display each time. In addition, key operations must be performed to return to the original screen display after recording, which has the disadvantage that key operations become complicated.

The present invention has focused on these points, and its purpose is to provide a waveform measuring device that can obtain a display screen suitable for recording with a single key operation.

Means for Solving Problems〉 The waveform measuring device of the present invention is a waveform measuring device having a recording mode function for recording a display screen, which includes character elements, graphic merits, and measurement conditions for creating the display screen. A system memory in which data is stored, a character memory in which character display data created based on the data stored in this system memory is stored, and a character memory created based on the data stored in the system memory. A graphic memory that stores graphic display data; a waveform memory that stores waveform display data created based on the data stored in the system memory; and a waveform memory that stores waveform display data created based on data stored in the system memory. The present invention is characterized in that it is provided with an arithmetic control section that creates the character display data and graphic display data for each mode and controls the data to be stored in the character memory and the graphic memory.

<Operation> When the recording mode is selected, a recording screen is automatically created and displayed and recorded, and after the recording operation is executed, the original display screen is created and displayed again. Become.

As a result, a screen suitable for recording can be obtained with a single key operation without complicated key operations as in the conventional case.

<Example> Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.
In the figure, 1 is a system memory in which data including character elements, graphic metrics, and measurement conditions for creating a display screen is stored, and 2 is character display data created based on the data stored in the system memory 1. 3 is a graphic memory in which graphic display data created based on the data stored in the system memory 1 is stored; 4 is a graphic memory in which graphic display data is created based on the data stored in the system memory 1; Each of these memories 1 to 4 is connected to an arithmetic control unit (CPU) 5 via a bus B. Also connected to the bus B are a CRT controller 7 for controlling a CRT 6 used as a display, a display controller 8, and a print controller 9. Note that the display controller 8 and the print controller 9 are formed into, for example, a gate array. The arithmetic control unit 5 creates character display data and graphic display data for each mode and stores these data in the character memory 2 and graphic memory 3 in accordance with the setting change between the display mode and the recording mode. . The CRT controller 7 sends the synchronizing signal S to the CRT6. The 0 display controller 8 that outputs to the display controller 8 and the print controller 9 has a character memory 2. Data to be displayed is added from the graphic memory 3 and waveform memory 4, and control signals are also added from the arithmetic control section 5. The display controller 8 outputs a video signal V to the CR'I' 6 and the print controller 9.

A control signal is also applied to the print controller 9 from the arithmetic control section 5. The video signal V applied to the print controller 9 is once stored in the buffer memory 10, and then outputted again to the printer 11 via the print controller 9 and recorded.

12 is a keyboard including operation setting keys, and is connected to bus B.

The operation of the apparatus configured as described above will be explained according to the flowchart shown in FIG.

Turn on the record key of the keyboard 12 while the image for the display mode as shown in FIG. Step ■).

When the recording mode is set, the arithmetic control unit 5 creates graphic display data for the recording mode based on the data stored in the system memory 1 and updates and stores it in the graphic memory 3 (step ■).
Create character display data for the recording mode and update and store it in the character memory 2 (step ■). Based on the data thus updated and stored, the image for the recording mode as shown in FIG. 4 is displayed on the CRT 6. At the same time (step ■), the printer 11 executes a recording operation (step ■). When the screen recording is completed in this way, the recording mode is canceled and the display mode is returned (
), and the arithmetic control unit 5 creates graphic display data for the display mode based on the data stored in the system memory 1 and updates and stores it in the graphic memory 3 (step ■), and also displays the character for the display mode. The data is created and updated and stored in the character memory 2 (step 2). Based on the updated and stored data, the display mode image as shown in FIG. 3 is again displayed on the CRT 6 (step 2). ).

In this way, by setting the recording mode with a single key operation on the keyboard, the character memory 2 and graphic memory 3 display the display image in the recording mode with the setting information areas B and C erased. The data to be created will be automatically updated and stored, and an image with setting information areas B and C erased will be displayed on the CRT 6, and the image will be recorded by the printer 11, and key operations will be the same as before. It's much easier compared to

In the above embodiment, an example of a digital oscilloscope has been described, but the present invention is also effective for other waveform measurement devices that combine a display and a recorder, such as a waveform memory recorder.

Further, in the above embodiment, an example was shown in which only the measured waveform is displayed as a recording screen, but the present invention is not limited to the embodiment, and the information to be recorded may be edited as appropriate depending on the purpose.

<Effects of the Invention> As described above, according to the present invention, it is possible to realize a waveform measuring device that can display a screen suitable for recording and record the screen with a single key operation.
