SEARCH:SEARCH
1:TRIGger:A:LOGIc:THReshold:RF_PHASe?
might return
4.500E+1, indicating that the search’s threshold is 45 degrees.
Following is a
n example command sequence showing how to generate a single
search mark on the RF_PHASe waveform when the waveform is logic 0 (less
than 45 degrees):

SEARCH:SEARCH<x>:TRIGger:A:LOWerthreshold:CH<x>
This command specifies the lower threshold of the channel waveform to be
used in a search. This setting is applied to all channel searches that use a lower
threshold.
SEARCH<x> is the search number, which is always 1, and CH<x> is
the channel number, which can be 1–4.

Syntax
SEARCH:SEARCH<x>:TRIGger:A:LOWerthresh old:CH<x> {TTL}
SEARCH:SEARCH<x>:TRIGger:A:LOWerthresh old:CH<x>?
Arguments
TTL specifies a preset TTL high level of 1.4 V.
SEARCH:SEARCH<x>:TRIGger:A:LOWerthreshold:MATH
This command specifies the math waveform lower threshold to determine where
to place a mark. This setting is applied to all math searches that use a lower
threshold.
SEARCH<x> is the search number, which is al
ways 1.
