Adjustment procedure 13, "Sweep, DAC, and Main Coil Driver
Adjustments" should be performed prior to this procedure,
particularly if the Al6 Scan Generator Assembly, A19 DAC Assembly,
A20 Main Coil Driver Assembly, or AllA YTO are adjusted, repaired,
or replaced. The YTX TUNE/YTO TUNE 1 (-3 V/GHz) signal from
A19 DAC Assembly directly affects the tuning of both the AllA YTO
and A6A8 YTX. Adjustments
A19 DAC Assembly, and A20 Main Coil Driver Assembly have a direct
affect on YTX/YTO tracking in
frequency bands.
1. Set the spectrum analyzer LINE switch to STANDBY. Turn the
