Making the Output RF Spectrum (ORFS) Measurement
Figure 3-2 Output RF Spectrum (ORFS) Due To Modulation: Multiple
Offset Measurement
Figure 3-2 above shows offset measurements taken during an ORFS
due to modulation (multiple offset) measurement.
Figure 3-3 Output RF Spectrum (ORFS) Due To Modulation: Swept
Measurement
Figure 3-3 above shows a swept trace taken during an ORFS due to
modulation measurement. If averaging is turned on, the display is
averaged over successive sweeps until the required number of sweeps
has been reached. It then starts again with a fresh display.
