Tracking Adjustment Range
Description
The centering of the tracking oscillator range is adjusted in the factory to ensure that
the tracking adjustment functions properly. Over a period of 5 years, however, the center frequency of the tracking oscillator range may drift outside of acceptable limits. These limits are tested in the Tracking Adjustment Range performance test. This adjustment should only be performed if the Tracking Adjustment Range performance test has failed.
This adjustment recenters the tracking oscillator range. The A10 Tracking Generator is partially removed from the spectrum analyzer to perform this adjustment. A synthesized sweeper is used as the first local oscillator signal. A frequency counter is used to measure the output frequency.
