Syntax
SEARCH:SEARCH<x>:TRIGger:A:LEVel:RF_PHASe {<NR1>|ECL|TTL}
SEARCH:SEARCH<x>:TRIGger:A:LEVel:RF_PHASe?
Arguments
<NR3> is a floating point number that sets the threshold level, in Volts, to use
when searching on the RF Phase vs. Time trace.
ECL sets the threshold level to a preset ECL high level of -1.3V.
TTL sets the threshold level to a preset TTL high level of 1.4V.
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:FUNCtion
This command specifies the logic operator to be used in a logic search. <x> is
the search number, which is always 1.

Syntax
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:FUNCtion {AND|NANd|NOR|OR}
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:FUNCtion?
Arguments
AND places a mark if all conditions are true.
NANd places a mark if any of the conditions are false.
NOR places a mark if all conditions are false.
OR places a mark if any of the conditions are true.
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:INPut:CH<x>
This command specifies the logic condition to be used in a logic search w
hen the
input is an analog channel.
SEARCH<x> is the search number, which is always 1,
and
CH<x> is the channel number, which can be 1–4.

Arguments
HIGH specifies t
he logic high.
LOW specifies the logic low.
X specifies a "don't care" state.
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:INPut:CLOCk:EDGE
This comman
d specifies the clock edge condition (rising or falling) to be used in a
logic search. <x> is the search number, which is always 1.

Syntax
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:INPut:CLOCk:EDGE
{FALL|RISe}
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:INPut:CLOCk:EDGE?
Arguments
RISe specifies a rising edge.
FALL specifies a falling edge.
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:INPut:CLOCk:SOUrce
This command specifies the clock source to be used in a logic search. <x> is the
search number, which is always 1. If a clock source is defined, then the logic
search is determined by the state of the other inputs at the clock transition. If
no clock source is defined, then the logic search is determined only by the state
of the inputs.
