An automatic tuning system for a cavity in a passive hydrogen frequency standard is considered, which uses the excitation signal with phase modulation. Numerical and experimental tests have shown that the performance of this system is dependent on the extent of spectrum distortion resulting from the signal and asymmetry of the resonance curve in the UHF cavity.
