Commands Listed in Alphabetical Order
Arguments
TTL specifies a p
reset TTL high level of 1.4 V.
SEARCH:SEARCH<x>:TRIGger:A:LOWerthreshold:REF<x>
This command specifies the reference waveform lower threshold to determine
where to plac
e a mark. This setting is applied to all reference searches that use a
lower threshold.
SEARCH<x> is the search number, which is always 1, and REF<x> is the reference
channel number, which is 1–4.

Syntax
SEARCH:SEARCH<x>:TRIGger:A:LOWerthresh old:REF<x> {TTL}
SEARCH:SEARCH<x>:TRIGger:A:LOWerthresh old:REF<x>?
Arguments
TTL specifies a preset TTL high level of 1.4 V.
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.
(To specify the upper threshold for runt and transition searches, use the command
SEARCH:SEARCH<x>:TRIGger:A:UPPerthreshold:RF_AMPlitude.)
Conditions
MDO4000/B/C models only.

Syntax
SEARCH:SEARCH<x>:TRIGger:A:LOWerthresh old:RF_AMPlitude
{<NR3>}
SEARCH:SEARCH<x>:TRIGger:A:LOWerthresh old:RF_AMPlitude?
Related Commands
TRIGger:A:LOWerthreshold:RF
Arguments
<NR3> is a floating point number that specifies the lower threshold for the RF
Amplitude vs. Time trace, in Volts.
