Command Syntax
:COMPliance:USB:AUTosetup
The :COMPliance:USB:AUTosetup command automatically sets up the
oscilloscope for the selected signal quality test and USB compliance test packets.
Automatically set are:
• Horizontal scale and delay.
• Analog input channel(s) scale and vertical offset.
• Trigger mode and trigger level.
The :COMPliance:USB:AUTosetup command causes the oscilloscope to run (that
is, capture acquisitions that meet the trigger condition).
If you are testing the signal quality of real-world packets (instead of USB
compliance test packets), you may need to adjust the auto setup.
Note that gating of measurements can only be done via the oscilloscope's
horizontal controls. This can be done after the :COMPliance:USB:AUTosetup
command and before the :COMPliance:USB:RUN command. The horizontal
controls should be adjusted so that only the data to be tested is on screen when
the :COMPliance:USB:RUN command is executed. This is normally one packet of
data.
