DEVICE FOR PRODUCING A REFERENCE FREQUENCY SIGNAL

摘要

The invention relates to a device (1) for producing a reference frequency signal (Se) from the response of an atomic resonator (R) to a pumping signal (Fat) transmitted thereto, comprising: a first oscillator for production of a first signal (S1) of frequency (F0) as a function of the response signal (E1) from the resonator (R); a second oscillator (13) for production of a second signal (S2) at a frequency (NF0) which is equal to a whole multiple of that of the first signal (S1). According to the invention, the second oscillator is selected to produce a second signal (S2) close in frequency to the frequency of resonance for the resonator (R).
