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.
