Abstract

The theoretical analysis of the hydrogen maser cavity autotuning step system produced by the atom line duality modulation method is performed. The expressions for a random error due to the maser frequency fluctuations are obtained. The experimental data of the frequency measurements of CH1-75 masers, operating in the cavity autotuning mode, are given. The optimal parameters choice of a cavity servo system has allowed to improve the CH1-75 hydrogen maser frequency stability by 3-4 times and achieve Allan deviation (0.7-1.5)·10^-15 per 1 d
