In the modern world, information transmission systems, telecommunication and satellite navigation systems, as well as metrological services play an important role in our lives. However, the development of these systems leads to the constant need to upgrade the currently used quantum frequency standards. To improve the short-term stability of the frequency standard, a new method has been developed to upgrade the oscillator unit and the frequency standard output amplifiers. In the course of experimental studies of the metrological characteristics of the quantum frequency standard based on rubidium-87 atoms, the effectiveness of the new development was shown.
