Description
The sampling oscillator tank circuit is adjusted for a tuning voltage of
5.05 V dc when the sampling oscillator is set to 297.222 MHz. The
voltage monitored is actually the tuning voltage divided by 4.05. The
setting is then checked at other frequencies for the full tuning range of
the sampling oscillator.
