Examples
SEARCH:SEARCH1:TRIGger:A:LOGIc:THReshold:RF_AMPlitude 1.5 sets
the search’s threshold to 1.5
V.
SEARCH:SEARCH1:TRIGger:A:LOGIc:THReshold:RF_AMPlitude? might
return 1.5, indicating that the search’s threshold is 1.5V.
Following is an example command sequence showing how to generate a single
search mark on the RF_AMPLitude waveform when the waveform is logic 0
(less than 1.5V):

SEARCH:SEARCH<x>:TRIGger:A:LOGIc:THReshold:RF_FREQuency
This command specifies the threshold to use when searching the RF
Frequency vs. Time waveform. (It does the same thing as the command
SEARCH:SEARCH<x>:TRIGger:A:LOWerthreshold:RF_FREQuency.) This
command is used together with SEARCH:SEARCH<x>:TRIGger:A:LOGIc:
INPut:RF_FREQuency to search for an instance when the RF Frequency vs.
Time waveform goes higher or lower than the specified threshold.
SEARCH<x> is
the search number, which is always 1.
Conditions
MDO4000/B/C models only.

This command specifies the threshold, in degrees, to use when
searching the RF Phase vs. Time waveform. (It does the same thing as

command is used together with SEARCH:SEARCH<x>:TRIGger:A:LOGIc:

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.
