Figure 3-1 Output RF Spectrum (ORFS) Due To Modulation: Single Offset
Measurement
Figure 3-1 above shows a single offset trace taken during an ORFS due
to modulation measurement. The vertical bars show the portion used to
measure power due to modulation. If averaging is turned on, the trace
is averaged with previous traces using video averaging. The displayed
value is the average of points within the vertical bars.
