At the recent SATELLITE 2006 show in Washington, DC, Symmetricom unveiled a brand new Cs4000 Cesium Frequency Standard equipped with a new color front panel Graphical User Interface (GUI) and many new features. The Cs4000 is ideally suited for the stringent requirements of a wide array of applications, including test and measurement, military communications, satellite ground stations, military test ranges, television broadcast and many others needing a primary frequency reference.

“The front panel graphical user interface and Ethernet connectivity allow for monitor and control functionality that is unrivaled in the industry,” commented Doug Lowrie, product marketing manager for Symmetricom. “The ability to have continual access to mission critical instrumentation is a major issue for our customers; the Ethernet interface on the Cs4000 will provide continual access to vital cesium operating parameters.”

The Cs4000 is a 3U rack mount master clock that provides stable and accurate Radio Frequency (RF) signals that are derived from an atomic resonance in the cesium atom. This resonance in the cesium atom serves as the international definition of the duration of the second. When the Cs4000's time is synchronized to a National Measurement Institute (such as the U.S. National Institute of Standards and Technology), it acts as a highly accurate master clock that provides signals in timing systems.

The Cs4000 provides multiple standard outputs, optional outputs that can be user configured and an internal options area for custom specials. The front panel display and Ethernet interface provide a customer interface and ease of use capability unique for this style of instrument. It is the only cesium available with Ethernet connectivity for remote monitoring and easy to use menu driven front panel interface.

Advanced Cesium III digital technology is at the core of the Cs4000 and is a direct result of Symmetricom's ongoing research and development efforts which have led to performance improvements in long term stability and accuracy. For more information on the Cs4000 II, click here.
