Method and system for electron density measurement

A method of controlling a diagnostic system, said diagnostic system comprising a multi-modal resonator to produce a cavity resonance, a power source to produce an output frequency, a detector to produce a transmission signal, and a controller coupled to said power source and said detector, said method comprising:

• activating said controller;
• selecting a varactor voltage control in order to control a varactor voltage of said power source;
• selecting a detector voltage monitor in order to monitor said transmission signal from said detector;
• and
• adjusting said varactor voltage for said power source using said controller.
