Root Level Command Syntax Diagram
AUToscale
Command :AUToscale
The AUToscale command causes the oscilloscope to automatically select the
vertical sensitivity, vertical offset, trigger source, trigger level, and timebase
settings for optimum viewing of any input signals. The trigger source is the
lowest numbered channel on which the trigger was found. If no trigger is
found, the oscilloscope defaults to auto-trigger. The display window
configuration is not altered by AUToscale.
Example OUTPUT XXX;":AUTO SCALE"
To demonstrate a quick oscilloscope setup requires hardware. Use the AC
CAL OUTPUT signal available at the rear panel of the card. The square wave
put out by the AC CAL OUTPUT is normally used for calibration and probe
compensation.
Connect the AC CAL OUTPUT signal from the rear panel output connector to
CHAN 1, also on the rear panel. Ensure that the mainframe is connected to a
controller. Enter the program listed on the next page and execute it.
The following program expects the oscilloscope to be connected to a signal.
