One kind of reproducing apparatus and method for atomic clock output frequency

The present invention discloses an apparatus and method for reproducing the output frequency of the atomic clock, belonging to the field of atomic clocks. Means: acquisition module, for collecting atomic clock output frequency after the reboot; Comparative adjustment module for outputting the output frequency is compared with a predetermined frequency, to obtain a comparison result, and the result of the comparison, adjusting the magnetic field in the resonant cavity atomic clock size, so that the atomic clock to recover the predetermined output frequency after the output frequency reboot. Method: collect atomic clock output frequency re-boot; the output frequency is compared with a predetermined output frequency, to obtain a comparison result, and the result of the comparison, adjusting the magnetic field magnitude atomic resonant cavity, so that the atomic clock output after rebooting the restored to the predetermined frequency of the output frequency. The present invention is applicable to an atomic clock output frequency very demanding applications.
