FREQUENCY SHIFTS IN A RUBIDIUM FREQUENCY STANDARD DUE TO COUPLING TO ANOTHER STANDARD

Abstract:	Highly reliable timing systems, such as used on board satellites, may incorporate a hot standby atomic clock besides the active one. RF couplings between them may affect the performance of the active clock. We have investigated the effect of such couplings between two rubidium atomic clocks, and found that they will add an oscillatory term to the Allan Variance of the active clock, degrading its frequency stability, and that under certain circumstances they may also shift the active clock's operating frequency.
