Commands Listed in Alphabetical Order
set with the SEA
RCH:SEARCH<x>:TRIGger:A:LOWerthreshold:CH<x> and
SEARCH:SEARCH<x>:TRIGger:A:UPPerthreshold:CH<x> commands.
PULSEWIdth tr
iggers when a pulse is found that has the specied
polarity and is either inside or outside the limits as specied by
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:PATtern:WHEn:LESSLimit and
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:PATtern:WHEn:MORELimit.
The polarity is selected using the SEARCH:SEARCH<x>:TRIGger:A:RUNT:
POLarity command.
TRANsition triggers when a pulse crosses both thresholds in the same direction
as the specied polarity and the transition time between the two threshold
crossing
s is greater or less than the specied time delta.
SEARCH:SEARCH<x>:TRIGger:A:UPPerthreshold:CH<x>
Sets or returns the channel waveform upper threshold to determine where to
place a mark. This setting is applied to all channel searches that uses an upper
threshold.
SEARCH<x> is the search number and CH<x> is the channel number.
