Abstract

In this paper, we determine the formation peculiarities of a microwave excitation signal in the quantum frequency standard on cesium-133 atoms. To improve the characteristics of the microwave excitation signal, a method for optimizing the parameters of blocks and schemes of a quantum frequency standard with allowance for the established features is proposed. The studies showed that the use of this method can improve the spectral characteristics of the microwave excitation signal and reduce the step of tuning its output frequency. The experimental results allowed establishing that the use of this method improves the output frequency stability of the quantum standard by 20%. The established peculiarities create conditions for new research aimed at developing methods and techniques for improving the characteristics of the microwave excitation signal.
