Low-noise oscillator rubidium PRS10-深圳加泰晶体科技有限公司

The PRS10 Rubidium Atomic Oscillator is a high-performance Rubidium Atomic Oscillator produced by SRS in the United States. It has the characteristics of low phase noise, low drift, and high stability. It can be widely used in fields such as telecommunications, time system, radar, and measurement standards.

The PRS10 Rubidium Atomic Oscillator is a high-performance Rubidium Atomic Oscillator produced by SRS in the United States. It has the characteristics of low phase noise, low drift and high stability. It can be widely used in fields such as telecommunications, time system, radar, and measurement standards. PRS10 is an ultra-low phase noise (-130dBc/Hz@10Hz) 10MHz rubidium atomic oscillator device. The extremely low monthly aging rate (<5E-11) makes it very suitable as a time base component for precise frequency measurement. The oscillator has a 1pps input port that can be used for external reference standards (such as GPS) for phase lock and has a 72-hour Strautm 1 Level retention capability. The lifetime of the rubidium lamp is expected to reach 20 years and the device is equipped with a standard RS-232 computer interface.

1pps input for time stamping or phase lock

72-hour Strautm 1 Level retention ability

Can use RS232 interface for testing, control and calibration

Life span can reach twenty years
