Abstract

PURPOSE:To easily set a condition to be selected by reading out an icon image and its sequence stored in a memory with reference to a ROM table, etc., and selecting the condition by using the icon displayed. CONSTITUTION:When a menu to be set is selected on a screen, a frame memory 3 displays an icon image under the control of an MPU 1. The information for executing the icon or menu displayed on the screen is inputted to the MPU 1 by means of a pointing device processor 4. The MPU 1 executes a series of processing sequences after judging the processing sequence of the icon from the storing address of the icon. Since the observation condition set by the user can be displayed as one image and, in addition, the condition to be selected can also be set, the measurement or observation condition frequently used by the user can be readily reproduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of setting an observation state of a digital oscilloscope.

[0002]

2. Description of the Related Art In recent years, the observation state setting method for a digital oscilloscope has been made multifunctional to cope with various states, but the menu selection method for setting the observation state has become complicated. For example, a menu is displayed on the display screen by software, and the user selects the menu for setting the observation state to set the observation state to be set.

[0003]

For this reason, there is a problem that the operation becomes complicated when the user selects an observation state desired to be set, or the display is similar so that the display is easily confused. Therefore, an object of the present invention is to realize a digital oscilloscope in which the observation state set by the user selecting a large number of menus is displayed as one image and the conditions to be selected can also be set.

[0004]

SUMMARY OF THE INVENTION The present invention provides a microprocessor for controlling a main body in a digital oscilloscope having a screen for displaying an operation guidance screen and an input device for a user to input waveform observation conditions. And a display means for displaying a pointer on the screen for indicating a location on the entire screen, an image storage means for storing the image image of the icon, and a sequence setting for storing the processing method of the icon. Means, and means for setting and storing the selection condition of the processing method set by the sequence setting means, the user can select the observation condition with the displayed icon. The digital oscilloscope is characterized in that it is possible for the user to set the condition for selecting.

[0005]

[Operation] The icon image is stored in the frame memory managed by the bitmap, the processing sequence corresponding to the icon image is stored in the RAM, and the processing sequence and the icon image are read out by using the ROM table or the like for use. The observer can select the observation condition with the displayed icon, and the condition for selecting the icon can be set by the user himself.

1 is a block diagram of the basic hardware of the present invention.

In FIG. 1, reference numeral 1 denotes an MPU, that is, a microprocessor, which controls a digital oscilloscope and sets and executes a processing sequence in response to an instruction from the pointing device processor 4. 2 is an icon ROM,
In the initial state, the icon image in the initial state is stored, and after the processing sequence is set, the set icon image is stored. A frame memory 3 displays the set processing sequence and icon image on the display screen. The pointing device processor 4 controls a cursor and a touch panel for selecting icons and menus. These are connected by a common data bus and address bus.

A method of setting a processing sequence according to the present invention will be described with reference to the flowchart of FIG. First, (a)
The icon programming mode, that is, a state for setting a series of processing sequences is entered. Next, (b) after measuring the maximum value and the minimum value of the first input signal in channel 1 at 1 V / div and 1 ms / div, the second input signal In channel 2, select a menu that measures the average value at 0.5 V / div and 10 ms / div. When the operation of (b) is completed, (c) the icon programming mode is exited. Further, the series of processing sequences selected in (d) and (b) are assigned to the icons in the initial state stored in the icon ROM 2, and the set icon image (for example, the icon in the initial state is named) is displayed. Edit processing such as storing. Finally, (e) the set selection condition of the icon image, that is, the hierarchy from which to select is determined. With the above operation, the user can select the observation condition with the displayed icon and set the condition for selecting the icon by the user himself / herself.

FIG. 3 shows an example of a specific operation method. FIG. 3 (f) is a diagram in the case of setting the actual conditions of a series of processing sequences, and an operation of selecting a normal menu with a soft key and inverting it is performed. FIG. 3 (g) is a screen for selecting in which layer the set icon image is to be placed. At this time, this icon image is displayed in addition to the menu that normally appears in the selected menu. Figure 3 (h) is an icon image, (h)
-1 is an initial state icon, and (h) -2 is a set icon.

Further, the operation of such a hardware configuration will be briefly described. When the menu set in FIG. 3 (g) is selected, the frame memory 2 is controlled by the MPU 1,
The icon image is displayed. The information selected by the pointing device processor 4 to execute the icon or menu displayed on the screen is input to the MPU 1. Since the icon image is stored in the icon ROM 2, the MPU 1 determines which processing sequence is based on the storage address of the icon selected for execution.
Execute a series of processing sequences.

[0011]

As is clear from the above description,
The present invention has the following effects. Since the observation state set by the user is displayed as one image and the conditions to be selected can be set, the measurement or observation state frequently used by the user can be easily reproduced.
