SEARCH:SEARC
H<x>:TRIGger:A:UPPerthreshold:REF<x>
This command specifies the reference waveform upper threshold to determine
where to place a mark. This setting is applied to all reference waveform searches
that use an up
per threshold.
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:UPPerthresh old:REF<x> {TTL}
SEARCH:SEARCH<x>:TRIGger:A:UPPerthresh old:REF<x>?
Arguments
TTL specifies a preset TTL high level of 1.4 V.
SEARCH:SEARCH<x>:TRIGger:A:UPPerthreshold:RF_AMPlitude
For a runt or transition search using the RF Amplitude vs. Time
trace, this command specifies the upper threshold to be used by the
search engine. (To specify the lower threshold, use the command
SEARCH:SEARCH<x>:TRIGger:A:LOWerthreshold:RF_AMPlitude.)
Conditions
MDO4000/B/C models only.

{<NR3>}
SEARCH:SEARCH<x>:TRIGger:A:UPPerthresh old:RF_AMPlitude?
Related Commands
TRIGger:A:UPPerthreshold:RF
Arguments
<NR3> is a floating point number that specifies the threshold for the time domain
trace, in volts.
Examples
SEARCH:SEARCH1:TRIGger:A:UPPerthreshol d:RF_AMPlitude 1 sets the
upper threshold to 1V.
SEARCH:SEARCH1:TRIGger:A:UPPerthreshol d:RF_AMPlitude? might
return 1.000E+0, indicati
ng that the upper threshold has been set to 1V.
