Root Level Commands
:AUToscale
Command
:AUToscale
The :AUToscale command causes the oscilloscope to evaluate all input
waveforms and find the optimum conditions for displaying the waveform.
It searches each of the channels for input waveforms and shuts off
channels where no waveform is found. It adjusts the vertical gain and
offset for each channel that has a waveform and sets the time base on the
lowest numbered input channel that has a waveform.
The trigger is found by searching each channel, starting with channel 4,
then channel 3, channel 2, and channel 1, until a trigger waveform is
detected. If waveforms cannot be found on any vertical input, the
oscilloscope is returned to its former state.
Autoscale sets the following:
• Channel Display, Scale, and Offset
• Trigger Sweep, Mode, Edge, Source, Level, Slope, Hysteresis, and Holdoff
• Acquisition Sampling Rate and Memory Depth
• Time Base Scale and Position
• Marker Mode Set to Measurement
• Resets Acquisition Completion Criteria to 90%
Autoscale turns off the following:
• Measurements on sources that are turned off
• Functions
• Windows
• Memories
• InfiniiSim
Autoscale does not turn off:
• PrecisionProbe/PrecisionCable
No other controls are affected by Autoscale.
Example
This example automatically scales the oscilloscope for the input waveform.
