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. This adjustment
should only be performed if there is insufficient tracking adjustment
range.
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.
