Cesium Standards

Many complex electronic systems require a stable, highly accurate timebase. Communication, automatic test and measurement, and precision time-measurement systems all require accurate frequency standards. Traditionally, users have looked to atomic clocks (cesium or rubidium) for high stability and accuracy. With the FS700 LORAN-C Frequency Stan ...more

The Quartzlock range of distribution amplifiers are intended for use when multiple outputs from a single frequency standard/generator are required. This may be encountered in engineering labs, national standards labs, research and development, calibration labs and production. This is vital for the distribution of signals from other precision fr ...more

Traditionally, users have looked to atomic clocks (cesium) for high stability and accuracy. With the FS700 LORAN-C Frequency Standard, cesium-clock stability is now available at a fraction of the cost of atomic standards. The FS700 serves as a NIST traceable frequency reference in the US, Europe and Asia. ...more

Symmetricom's MHM 2010™ is the only commercially available active hydrogen maser with stand-alone cavity switching auto tuning manufactured in the USA. This technique enables the MHM 2010 to deliver long-term stability normally only attributed to the most stable of cesium atomic standards. ...more
