5. Sampler Assembly

Description and Procedure
No test equipment is required for this procedure.
here are three sampler assembly adjustments:
In the sampler match adjustment, as the internal DVM monitors the loop
input to the sampler, trim capacitors are adjusted to optimize the sampler
match over the full frequency range of the loop.
he 200 MHz loop gain adjustment is automatic. When this adjustment
is selected in the A6 adjustment menu, the synthesizer selects internal
calibration constants for optimum loop gain over the full frequency range of
the loop.
In the IF gain adjustment, the IF ampli er gain is adjusted as the internal
DVM monitors the IF output level to the YO loop.
1. urn the synthesizer to standby. At FL2 (see Figure 3-7), disconnect the
semi-rigid cable between FL2 and the A6 assembly.
