*STB? *TST? *WAI :AUToscale For example, :AUToscale /*The oscilloscope performs the AUTO function*/ :CLEar For example, : CLEar / * Clear all waveforms on the screen * / 15 / 136 Command format *STB? Function description Query the event register value of the status byte register. After the command is executed, the value of the status byte register is cleared. Return format The query returns an integer equal to the sum of the weights of all bits in the register. Command format *TST? Function description Perform a self-test and return the self-test results. Return format The query returns a decimal integer. Command format *WAI Function description Wait for the operation to complete.
Description Subsequent commands can be executed after the current operation command has been executed. Command format :AUToscale Function description Enable the automatic waveform setting function. The oscilloscope will automatically adjust the vertical scale, horizontal time base, and trigger mode according to the input signal to achieve the best waveform display. This command is equivalent to pressing the front panel AUTO Scale button.
Description ▷When applying the automatic waveform setting function, the theoretical frequency of the sine signal is not less than 10Hz; for the square wave signal, the theoretical value is related to the duty cycle, the duty cycle should be greater than 0.5%, and the amplitude should be at least 10mVpp (the probe ratio is 1X Time). ▷When the current status of the pass / fail function is to allow the test, if you send this command, the oscilloscope first turns off the pass / fail function, and then executes the automatic waveform setting function. ▷This command is invalid when the segment acquisition function is turned on or the history waveform is turned on.
Command format :CLEar Function description Clear all waveforms on the screen. If the oscilloscope is in the RUN state, the waveform will continue to be displayed.
