RIGOL Chapter 2 Command System
2-2 MSO1000Z/DS1000Z Programming Guide
:AUToscale
Enable the waveform auto setting function. The oscilloscope will automatically adjust the
vertical scale, horizontal timebase, and trigger mode according to the input signal to
realize optimum waveform display. This command is equivalent to pressing the AUTO key
at the front panel.
 Theoretically, waveform auto setting function requires that the frequency of sine is no
lower than 41Hz; the duty cycle should be greater than 1% and the amplitude must
be at least 20mVpp for square (the probe ratio is 1X).
 When the pass/fail function is enabled (see the :MASK:ENABle command), if you sent
this command, the oscilloscope will disable the pass/fail function firstly and then
execute the waveform auto setting function.
 When the waveform record function is enabled or during the playback of the
recorded waveform, this command is invalid.
:CLEar
Clear all the waveforms on the screen. If the oscilloscope is in the RUN state, waveform
will still be displayed. This command is equivalent to pressing the CLEAR key at the front
panel.
:RUN
:STOP
The :RUN command starts the oscilloscope and the :STOP command stops the
oscilloscope. These commands are equivalent to pressing the RUN/STOP key at the
front panel.
When the waveform record function is enabled or during the playback of the recorded
waveform, these commands are invalid.
