33 Trigger Commands
:TRIGger:ADVanced:COMM:PATTern
Command :TRIGger:ADVanced:COMM:PATTern <bit>[,<bit[,<bit[,<bit[,<bit[,<bit]]]]]
The :TRIGger:ADVanced:COMM:PATTern command sets the pattern used for
triggering the oscilloscope when in communication trigger mode. The
pattern can be up to 6 bits long. For NRZ type waveforms with positive
polarity, there must be at least one logic 0 to logic 1 transition in the
pattern. For NRZ waveforms with negative polarity there must be at least
one logic 1 to logic 0 transition in the pattern. For RZ type waveforms the
pattern must have at least one logic 1 bit for positive polarity. For RZ type
waveforms the pattern must have at least one logic - 1 bit for negative
polarity.
<bit> A 1, - 1, or 0.
Query
