Prs10 rubidium atomic oscillator is a high-performance rubidium atomic oscillator product produced by SRS company in the United States. It has the characteristics of low phase noise, low drift and high stability. It can be widely used in telecommunications, time series, radar, measurement standards and other fields. Prs10 is an ultra-low phase noise (- 130dbc)/ Hz@10Hz )10MHz rubidium atomic oscillation device. The extremely low monthly aging rate (< 5e-11) makes it very suitable for precise frequency measurement as a time-based component. The oscillator has a 1PPS input port, which can be used for phase locking of external reference standards (such as GPS) and has the holding capacity of 72 hours strautm 1 level. The service life of rubidium lamp is expected to be up to 20 years, and the device is equipped with a standard RS-232 computer interface.
