This article presents “Compass” TOKAMAK microwave diagnostics calibration and results accuracy enhancing experiment methodology. Main subject is microwave diagnostic system phase measurements description. Additional interest is mistakes, attendant to phase measurement. Emphasis is put on phase detectors measurements mistakes correction methodology; two different phase meter configurations are described. Phase detectors, based on AD8302 CPLD, results processing methodology are presented.
