Commands Listed in Alphabetical Order
Arguments
CH<x> specifies
one input channel as the edge source, where <x> = 1, 2, 3 or 4.
MATH<x> specifies the math waveform as the search source, where <x> = 1, 2, 3
or 4.
REF<x> specifies the reference waveform as the search source, where <x> =
1, 2, 3 or 4.
Examples
SEARCH:SEARCH1:TRIGGER:A:P ULSE:SOURCE REF1 sets the pulse trigger
source for search1 to the Reference 1 waveform.
SEARCH:SEARCH1:TRIGGER:A:P ULSE:SOURCE? might return
:SEARCH:SEARCH1:TRIGGER:A: PULSE:SOURCE MATH1, indicating the pulse
trigger source for search 1 is set to the Math 1 waveform.
SEARCH:SEARCH<x>:TRIGger:A:RUNT:POLarity:CH<x>
This command sets or queries the polarity setting for a runt trigger search to
determine where to place a mark. <x> is the search number or channel number.
Group
Search and Mark
Syntax
SEARCH:SEARCH<x>:TRIGger:A :RUNT:POLarity:CH<x>
{EITher|NEGAtive|POSITIVe}
SEARCH:SEARCH<x>:TRIGger:A :RUNT:POLarity:CH<x>?
Arguments
POSitive places a m ark when the rising edge crosses the low threshold and
the falling edge recrosses the low threshold without either edge ever crossing
the high threshold.
NEGative places a mark when the falling edge crosses the high threshold and
the rising edge recrosses the high threshold without either edge ever cro
ssing
the low threshold.
EITher places a mark on a runt of either polarity.
Examples
SEARCH:SEARCH1:TRIGGER:A:R UNT:POLARITY:CH2 NEGATIVE sets the
Channel 2 runt polarity for search 1 to negative.
SEARCH:SEARCH1:TRIGGER:A:R UNT:POLARITY:CH1? might return
:SEARCH:SEARCH1:TRIGGER:A: RUNT:POLARITY:CH1 POSITIV E, indicating
the Channel 1 runt polarity for search 1 is set to positive.
