Tracking Oscillator Adjustment (Option 002) - HP 8560A Service Manual

20. Tracking Oscillator Adjustment (Option 002)

Note This is not a routine adjustment. This adjustment should only be performed if
the Tracking Adjustment Range performance test has failed.
Assembly Adjusted
A10 Tracking Generator Assembly
Related Performance Test
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.
