Low phase noise rubidium clock, which can be tamed quote

Product Description:

The PRS10 Rubidium Atomic Oscillator is a high-performance product manufactured by SRS (Signal Recovery Systems), USA. It features low phase noise, low drift, and high stability, making it suitable for a wide range of applications in telecommunications, timing and synchronization, radar, and metrology standards.

The PRS10 is an ultra-low phase noise (-130 dBc/Hz@10Hz) 10 MHz rubidium atomic oscillator. Its extremely low aging rate (<5E-11) makes it ideal as a timebase component for precise frequency measurements.

The oscillator includes a 1pps input port for external reference standards such as GPS for phase locking and has a holdover capability of 72 hours at Strautm 1 Level. The rubidium lamp's expected lifespan is up to 20 years, and the device features a standard RS-232 computer interface.
