Commands Listed in Alphabetical Order
SEARCH:SEARC
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.
Conditions
MDO4000/B/C models only.

Syntax

SEARCH:SEARCH<x>:TRIGger:A:LOGIc:INPut:RF_PHASe?
Related Commands
TRIGger:A:LOGIc:INPut:RF
Arguments
HIGH specifies a high logic level.
LOW specifies a low logic level.
X specifies a “don't care” condition.
Examples
SEARCH:SEARCH1:TRIGger:A:LOGic:INPut:RF_PHASe HIGH specifies
to set a mark when the waveform goes above the logic threshold specified by
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:THReshold:RF_PHASe.
SEARCH:SEARCH1:TRIGger:A:LOGic:INPut:RF_PHASe? 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_PHASe.
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:PATtern:INPut:CH<x>
This command specifies the logic condition to be used in a logic search when the
input is an analog channel.
SEARCH<x> is the search number, which is always 1,
and
CH<x> is the analog channel number, which can be 1– 4.

{TRUe|FALSe|LESSthan|Than|EQual|UNEQual}
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:PATtern:WHEn?
Arguments
TRUe places a mark when the pattern becomes true.
FALSe places a mark when the pattern becomes false.
LESSthan placesamarkifthespecificpattern is true less than the time set by
the SEARCH:SEARCH<x>:TRIGger:A:LOGIc:PATtern:WHEn:LESSLimit
command.
Than places a mark if the specific pattern is true longer than the specified time set
by the SEARCH:SEARCH<x>:TRIGger:A:LOGIc:PATtern:WHEn:MORELimit
command.
EQual places a mark if the specific pattern is true longer than the time set by
the SEARCH:SEARCH<x>:TRIGger:A:LOGIc:PATtern:WHEn:LESSLimit
command, but less than the specified time set by the SEARCH:SEARCH<x>:
TRIGger:A:LOGIc:PATtern:WHEn:MORELimit command.
UNEQual places a mark if the specific pattern is true less than the time set by
the SEARCH:SEARCH<x>:TRIGger:A:LOGIc:PATtern:WHEn:LESSLimit
command, or longer than the specified time set by the SEARCH:SEARCH<x>:
TRIGger:A:LOGIc:PATtern:WHEn:MORELimit command.
