Abstract

The atomic clock clean-up system aims at improving the short term frequency stability while maintaining the good long term frequency stability of the atomic clock itself. A simulation model for the atomic clock clean-up system is established, which is paramount importance for design, simulation, and selection of the suitable equipments for atomic clock clean-up system. Based on the phase locked loop(PLL) structure, the phase noise of oscillator, phase detector noise and voltage controlled oscillator(VCO) quantization noise which influence the performance of the system are modeled respectively in this simulation model. Then, a clean-up experiment has been designed for a widely used cesium atomic clock to test the performance of the atomic clock clean-up system. The experiment results show that the short term frequency stability of the cesium atomic clock under test is improved with the reasonable selection of the system parameters, and its short term frequency stability which is not inferior to the hydrogen maser. This simulation model can also be applied to the simulation of other types of PLL systems by changing the corresponding noise model.
