Command Description
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:PATtern:WHEn:
LESSLimit
This command specifies the maximum time that the selected pattern
may be true.
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:PATtern:WHEn:
MORELimit
This command specifies the minim um time that the selected pattern
may be true.
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:THReshold:CH<x> This command specifies the channel threshold level for a logic
search.
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:THReshold:MATH This command specifies the math waveform threshold level for a
logic search.
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:THReshold:
REF<x>
This command specifies the reference waveform threshold level
for a logic search
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:THReshold:
RF_AMPlitude
This command specifies the threshold to use when searching the
RF Amplitude vs. Time waveform. (Same as the command
SEARCH:SEARCH<x>:TRIGger:A:LO Werthreshol d:RF_AMPlitude.)
This command is used together with
SEARCH:SEARCH< x>:TR IGger:A:LOG Ic:IN Put:RF _AM Plitude to
search for an instance when the RF Amplitude vs. Time waveform
goes higher or lower than the specified threshold.
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:LO Werthreshol d:RF_FREQuency.)
This command is used together with
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:INPut:RF_FREQuency
to search for an instance when the R F Frequency vs. Time
waveform goes higher or lower than the specified threshold.
SEARCH:SEARCH<x>:TRIGger:A:LOGIc:THReshold:
RF_PHASe
This command specifies the threshold, in degrees, to use when
searching the RF Phase vs. Time waveform. (It does the same thing
as
SEARCH:SEARCH<x>:TRIGger:A:L OWerthresho ld:RF_PHASe.)
This command is used together with
SEARCH:SEARCH< x>:TR IGger:A:LOG Ic:IN Put:RF _PH ASe to
search for an instance when the RF Phase vs. Time waveform goes
higher or lower than the specified threshold.
SEARCH:SEARCH<x>:TRIGger:A:LOWerthreshold:CH<x> This command specifies the lower waveform threshold level for
all channel waveform searches
SEARCH:SEARCH<x>:TRIGger:A:LOWerthreshold:MATH This command specifies the lower waveform threshold level for all
math waveform searches
SEARCH:SEARCH<x>:TRIGger:A:LOWerthreshold:REF<x> This command specifies the lower waveform threshold level for all
reference waveform searches
SEARCH:SEARCH<x>:TRIGger:A:LOWerthreshold:
RF_AMPlitude
This command specifies the threshold for RF Amplitude vs.
Time trace searches. For runt and transition searches, this
level is the lower threshold. For other search types, this is
the single threshold. This command is used together with
SEARCH:SEARCH< x>:TR IGger:A:LOG Ic:IN Put:RF _AM Plitude to
search for an instance when the waveform goes higher or lower
than the specified threshold.
