This command specifies the maximum time that the selected pattern
may be true.

This command specifies the minimum tim e that the selected pattern
may be true.

This command specifies the threshold to use when searching the
RF Amplitude vs. Time waveform. (Same as the command
SEARCH:SEARCH<x>:TRIGger:A:LOWerthreshold: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 s pecifi ed threshold.

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

waveform goes higher or lower than the specified threshold.

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:LOWerthreshold:RF _PHASe.)
This command is used together with

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.
