an ORFS due to switching transients 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.

Troubleshooting Hints

The Output RF Spectrum measurement, along with the Phase and
Frequency Error measurement, can reveal numerous faults in the
transmit chain, such as the I/Q baseband generator, filters & modulator.
