Cesium Frequency Standard

Dependable, reliable, accurate and stable frequency standards for navigation, communications and timing applications.

Cesium beam frequency and time standard instruments from Symmetricom meet the most stringent requirements demanded by commercial, military and space applications. Our Cesium instruments are built to provide stand-alone dependability, ease of use, and ease of installation. A three decade legacy of reliability makes them the preferred choice in the critical time or frequency systems found in telecommunications timing, calibration and metrology laboratories, satellite tracking stations and spaced-based master time standards.
