Interference Suppression of Passive Hydrogen Frequency Standards

  • TIME AND FREQUENCY MEASUREMENTS
  • Published:
Measurement Techniques Aims and scope

The influence of harmonic interference on the metrological characteristics of the output signal of a passive hydrogen frequency standard is analyzed. It is shown that the additional signals in the control circuit generated by the interference lead to the appearance of a frequency shift or parasitic modulation of the frequency of the standard. Results of an experimental investigation of interference suppression of passive hydrogen frequency standards are presented and methods of increasing interference suppression are also considered. The results obtained confirm a theoretical analysis.
