PM Display

The Phase Modulation Display shows Phase vs. Time. The vertical axis units are degrees and the
horizontal axis units are seconds. When taking measurements, only the first burst in the Analysis period is
analyzed. No trace points are shown for data outside the first detected burst, nor are measurements made
on data outside the first detected burst.

Description
Shows or hides the graticule.
Shows or hides the readout for the selected marker in the graph area.
The trace in the FM display can be set to a maximum of 100,000 points (however, the
actual number of trace points can extend up to 500,000 points if Max trace points is
set to Never Decimate). If the Analysis Length includes more than the selected Max
trace points value, the trace is decimated (using the method specified with the Detection
control) to be equal to or less than the Max trace points setting (except when Max trace
points is set to Never Decimate). This decimated (or undecimated) trace is what is used
for marker measurements and for results export.
