Adjustments and Correction Constants

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.
