:TRIGger:ADVanced:COMM:POLarity
Command :TRIGger:ADVanced:COMM:POLarity {POSitive | NEGative}
The :TRIGger:ADVanced:COMM:POLarity command directly controls the
trigger slope used for communication trigger. When set to a positive value,
the rising edge of a pulse or waveform is used to trigger the oscilloscope.
When set to a negative value, the falling edge of a pulse or waveform is
used.
The polarity setting is also used to check for valid patterns. If you are
trying to trigger on an isolated 1 pattern, you should set the polarity to
positive. If you are trying to trigger on an isolated -1 pattern, you should
set the polarity to negative.
