FREQUENCY STANDARD


Symmetricom’s 5071A primary frequency standard delivers unsurpassed accuracy, stability and reliability for the most demanding laboratory and field applications.
Metrology and Calibration Labs
The 5071 offers exceptional frequency stability which is a key specification that directly affects a laboratory's ability to deliver timekeeping and calibration services to its clients. With a stability specification for 30-day averaging time, the 5071A can keep extremely predictable time and phase for long periods. Further, the 5071A can be used for long-term averaging of noisy signals such as GPS.
The Symmetricom Cs4000 is a new cesium frequency standard platform that provides exceptional performance in a configurable 3U rack mount chassis. The Cs4000 is designed for high precision timing and frequency applications requiring high stability, low noise RF and 1PPS reference signals. Symmetricom's advanced Cesium III digital technology is the engine that drives this exceptional performance.

Designed for portability, the CSIII is a functional, versatile Cesium Reference Standard that performs as a primary reference standard and calibration standard in applications including satellite tracking stations, positioning and navigation, and broadcast communications.
