SEARCH:SEARCH
1:TRIGger:A:LOWerthreshold:RF_FREQuency?
might
return 100.0E+6, indicating that the lower threshold has been set to 100 MHz.
Following is a
n example command sequence showing how to generate a single
search mark on the RF_FREQuency waveform when the waveform is logic 0
(less than 1 MHz):

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:LOWerthresh old:RF_PHASe {<NR3>}
SEARCH:SEARCH<x>:TRIGger:A:LOWerthresh old: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:LOWerthreshol d:RF_PHASe 15 sets the
lower threshold for the RF Phase vs. time trace to 15 degrees.
SEARCH:SEARCH1:TRIGger:A:LOWerthreshol d:RF_PHASe? might return
0.0e+0, indicating that the trace is not turned on.
