Description and Procedure
he unleveled status indicator is displayed when the instrument is unleveled
as the synthesizer sweeps over speci c frequency ranges in fast continuous
sweep, and fast and slow single sweep operation. Because of the synthesizer's
power accuracy and atness performance, a power meter is not required for
this measurement. he following procedure tests the most likely worst case
situations for maximum leveled power.

synthesizer and let it warm up for at least one hour.

output. If the synthesizer has a step attenuator, you can
simulate a good match by decoupling the step attenuator from
the ALC and setting the attenuator to 20 dB.
