PM/AM convertion tests

Question asked by sneruson on May 7, 2015
How can I tested convertion PM/AM signal in resonator of ESR spectrometer Varien 7800 with microwave bridge E102. This device have klystron generator on 9.5GHz with frequency modulation of this signal on 70KHz. This frequency modulated signal converted in amplitude modulation signal in waveguide resonator. In this resonator I put my samples for investigation. Than this amplitude modulated signal go on semiconductor's detector and i must measure amplitude and phase of this signal And I must compare this signal with the first signal with the best posible accuracy. Thanks to all.
