Autoscale
The AUTOSCALE feature performs a very useful function on unknown
waveforms by setting up the vertical channel, time base, and trigger level of
the instrument.
The syntax for the autoscale function is:
:AUTOSCALE<terminator>
Setting Up the Instrument
A typical oscilloscope setup would set the vertical range and offset voltage,
the horizontal range, delay time, delay reference, trigger mode, trigger level,
and slope. A typical example of the commands sent to the oscilloscope are:
:ANALOG1:PROBE X10;RANGE 16;OFFSET 1.00<terminator>
:TIMEBASE:MODE NORMAL;RANGE 1E-3;DELAY 100E-6<terminator>
This example sets the time base at 1 ms full-scale (100µs/div) with delay of
100 µs. Vertical is set to 16V full-scale (2 V/div) with center of screen at 1V
and probe attenuation set to 10.
