Product overview
The SYN3204 GPS Beidou domesticated rubidium atomic frequency standard is a high-precision frequency standard independently developed and manufactured. It receives the GPS Beidou satellite signal, so that the output frequency of the rubidium oscillator is synchronized with that of the GPS Beidou satellite cesium atomic clock. It improves the long-term stability and accuracy of the frequency signal, and provides the high precision time and frequency standard of the cesium clock magnitude. It is a cost-effective time-frequency product replacing the cesium clock by communication, broadcasting and other departments.
Key word: Rubidium frequency standard, GPS tame rubidium clock, GPS atomic clock, rubidium atomic frequency standard, time base rubidium clock
