Source Spur Avoidance Tracking Adjustment

Source Spur Avoidance Tracking Adjustment
This adjustment optimizes tracking between the YO (YIG oscillator) and the cavity
oscillator when they are frequency offset to avoid spurs. Optimizing YO-cavity oscillator
tracking reduces potential phase-locked loop problems.
Analyzer warmup time: 30 minutes.
