SEARCH:SEARC
H<x>:TRIGger:A:LOGIc:INPut:REF<x>
This command specifies the logic condition of the reference waveform to be
used in a logic search.
SEARCH<x> is the search number, which is always 1, and
REF<x> is the
reference channel number, which can be 1–4.

Syntax
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:INPut:REF<x> {HIGH|LOW|X}
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:INPut:REF<x>?
Arguments
HIGH specifies a high logic level.
LOW specifies a low logic level.
X specifies a “don't care” condition.
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:INPut:RF_AMPlitude
This command specifies the logic criteria to search for when searching using
the RF Amplitude vs. Time trace. This command is used together with
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:THReshold:RF_AMPlitude to
search for an instance when the waveform goes higher or lower than the specified
threshold. “LOW” specifies to only set a mark when the RF_AMPlitude
waveform drops below the logic threshold; likewise, “HIGH
” specifies to set a
mark when the waveform goes above the logic threshold. “X” specifies “don’t
care”.
SEARCH<x> is the search number, which is always 1.
Conditions
MDO4000/B/C models only.

SEARCH:SEARCH
1:TRIGger:A:LOGic:INPut:RF_AMPlitude HIGH
specifies to set a mark when the waveform goes above the logic threshold specified
by SEARCH:SEARCH<x>:TRIGger:A:LOGIc:THReshold:RF_AMPlitude.
SEARCH:SEARCH1:TRIGger:A:LOGic:INPut:RF_AMPlitude? might
return HIGH, indicating that the search engine has been set to set a
mark when a waveform goes above the logic threshold specified by
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:THReshold:RF_AMPlitude.
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:INPut:RF_FREQuency
This comm
and specifies the logic criteria to search for when searching using
the RF Frequency vs. Time trace. This command is used together with
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:THReshold:RF_FREQuency to
search for an instance when the waveform goes higher or lower than the specified
threshold. “LOW” specifies to only set a mark when the RF_FREQuency
waveform drops below the logic threshold; likewise, “HIGH” specifies to seta
mark wh
en the waveform goes above the logic threshold. “X” specifies “don’t
care”.
SEARCH<x> is the search number, which is always 1.

H<x>:TRIGger:A:LOGIc:INPut:RF_PHASe
This command specifies the logic criteria to search for when searching
using the RF Phase vs. Time trace. This command is used together with
SEARCH:SEAR
CH<x>:TRIGger:A:LOGIc:THReshold:RF_PHASe to search for
an instance when the waveform goes higher or lower than the specified threshold.
“LOW” specifies to only set a mark when the RF_PHASe waveform drops below
the logic threshold; likewise, “HIGH” specifies to set a mark when the waveform
goes above the logic threshold. “X” specifies “don’t care”.
SEARCH<x> is the
search number, which is always 1.
