By receiving and demodulating the Beidou (or GPS) signal to tame the cuckoo clock, the frequency accuracy of the 10 MHz output signal of the Rb Clock can be improved, and the aging phenomenon of the Rb clock can be weakened to some extent.
The XHTF3316N8 (series) Taming Atomic Frequency Standard is a high precision atomic frequency standard device. By receiving and demodulating the Beidou (or GPS) signal to tame the cuckoo clock, the frequency accuracy of the 10 MHz output signal of the Rb Clock can be improved, and the aging phenomenon of the Rb clock can be weakened to some extent. At the same time, the 10MHz signal of the Rb clock is locked by the phase-locked loop circuit to the high-intensity crystal oscillator with high instantaneous stability and low phase noise, thus obtaining a 10MHz clock reference with high accuracy, high instantaneous stability and low phase noise. Can be applied to communication base stations, electronic countermeasures, laboratory and deep space exploration.
Features
■ Double clock double redundant hot backup;
■ Low phase noise;
■ High instantaneous stability.
