SEARCH:SEARCH<x>:TRIGger:A:LOWerthreshold:RF_PHASe
This command specifies the lower threshold, in degrees, for searching the RF
Phase vs. Time waveform. For runt and transition searches, this level is thelower
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_PHASe.)
Conditions
MDO4000/B/C models only.

Syntax
SEARCH:SEARCH<x>:TRIGger:A:LOWerthreshold:RF_PHASe {<NR3>}
SEARCH:SEARCH<x>:TRIGger:A:LOWerthreshold:RF_PHASe?
Related Commands
TRIGger:A:LOWerthreshold:RF
Arguments
<NR3> is a floating point number that specifies the threshold for the time domain
trace, in degrees.
Examples
SEARCH:SEARCH1:TRIGger:A:LOWerthreshold:RF_PHASe 15 sets the
lower threshold for the RF Phase vs. time trace to 15 degrees.
SEARCH:SEARCH1:TRIGger:A:LOWerthreshold:RF_PHASe? might return
0.0e+0, indicating that the trace is not turned on.

SEARCH:SEARCH<x>:TRIGger:A:PULSEWidth:HIGHLimit
This command specifies the upper limit, in seconds, when searching the record
for pulses whose widths are within or outside of a specified range of two values.
(Use SEARCH:SEARCH<x>:TRIGger:A:PULSEWidth:LOWLimit to specify
the lower limit of the range.)

Arguments
POSITIVe places a mark only when the polarity of the pulse is positive.
NEGative places a mark only when the polarity of the pulse is negative.
