Following is an
example command sequence showing how to generate a single
search mark on the RF_PHASe waveform when the waveform is logic 0 (less
than 45 degrees):

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.)

To find all pulses in the waveform record with durations (widths) that fall outside
of the range of 100 nanoseconds to 110 nanoseconds:

This command specifies the lower limit, in seconds, when searching the record
for pulses whose widths are within or outside of a specified range of two values.
