RF I & Q vs Time Display
This is a plot of the baseband In-Phase (I) and Quadrature (Q) components of a modulated carrier. The plot
is in the time domain, with I and/or Q values the Y-axis.
Note that the trace(s) in the RF I & Q vs. Time display can be set to a maximum of 100,000 points
(however, the actual number of trace points can extend up to 1,000,000 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 speci
fi
ed 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. You can set the Max
trace points on the
