The following is a detailed description of the specific working principle of the present invention:
as shown in fig. 1, clicking the data input box in the trigger pop-up window will call out the keyboard window body area of the present invention. The data length in the binary display frame 002 of the display area of the present invention is converted from the byte length in the trigger popup, and the length of 1 byte = 8-bit wide, that is, if the trigger setting data length is 1 byte at this time, the data length in the binary display frame 002 of the present invention is 8. Of course, if not bytes but the data bit width length of the trigger setting, the data length of the display frame of the present invention is directly equal to that length.
As shown in fig. 1 or 4, the first time the keyboard window area of the present invention is called up will be in binary input mode. The keyboard window area is called out again after being closed, and the state before being closed is restored, for example: and if the state is 16-system state before closing, the state is restored to 16-system input state. As shown in fig. 2 or 3, when the present invention is currently in the 16-ary input mode, the cursor position in the display frame is determined, and if the cursor position is at the head, the digital input area 004 is possibly partially masked, and the masking rule is according to the bit width length, and the specific rule is as follows:
when the bit width length is 5, 9, 13, 17, 20, 25, 29, only "0" and "1" are available;
when the bit width length is 6, 10, 14, 18, 21, 26, 30, only "0", "1", "2", "3" are available;
when the bit width length is 7, 11, 15, 19, 22, 27, 31, only "0", "1", "2", "3", "4", "5", "6", "7" is available;
all otherwise available.
As shown in fig. 2, that is, when the bit width length is 11, only "0", "1", "2", "3", "4", "5", "6", "7" are available. In the current input mode, the display frame and the title area are distinguished by highlight colors, the binary display frame area is clicked, the input mode is switched, the keys are shielded according to different input modes, when the input mode is in the 2-binary mode, the numerical value number input area 004 only has '0', '1' keys, and other keys are invalid when being clicked. The "X" key indicates that the number is irrelevant, and a number of binary 4 data length is converted into a number of 1 16, and if the 4 numbers of binary data do not contain "X", the conversion is normally performed into 16. If 4 digits of the binary data are all 'X', the binary data is converted into 'X' in 16 system, and otherwise, the binary data is converted into a question mark symbol in 16 system. The X key is shielded or not according to different trigger type requirements.
Clicking on the clickable number in number entry area 004 will previously replace the number selected by the cursor in the display box. Clicking the cursor selection key area 005 will process the cursor in the display frame, move left and right, or select the number completely, or move left and right of the cursor through the left and right entity keys on the 4-in-1 instrument, if the cursor is in the state of selecting the number completely, then inputting or changing the number through the universal knob, will change all the numbers in the displayed money under the current system input mode at the same time. The universal knob on the 4-in-1 instrument can also be operated to change the number selected by the cursor or the position of the cursor, and the function of changing the position of the cursor currently or the function of changing the number selected by the cursor is switched by pressing the universal knob. As shown in fig. 5, the working mode of the entity in general will make a prompt symbol on the text prompt bar 003, if the "value" in the prompt is highlighted at this time, rotating the general knob will change the size of the value selected by the cursor, if the value is changed by using general selection, when the value exceeds the number in the scale range of the scale, the value will be carried forward or retreated. If the cursor in the prompt is highlighted at the moment, the cursor position is rapidly changed by rotating the universal knob, and the cursor moves left and right on the numbers in the display frame.
Once the value in the currently selected binary display frame is changed, the value in the other binary display frame is correspondingly converted and directly output to the outside.
The technical scheme adopted by the invention comprises two system input modes and displays the two systems, thereby not only facilitating the input of the user, but also reducing the calculation time of the user. The invention quickly positions the number to be changed by the input mode of combining the universal knob and the two keys with the virtual key, reduces the occupation of the entity key on the oscilloscope panel and simultaneously reserves the convenience of input. The invention automatically limits the input extreme value according to different input requirements, and reduces the trouble that the user has errors due to the fact that the input exceeds the extreme value. The invention effectively solves the requirement of oscilloscope users on the binary input and reduces the time for the users to carry out the binary conversion calculation. The mode switching and key shielding effects of the invention also improve the user experience.
