SAN JOSE, Calif., Dec. 13, 2005 (PRIMEZONE) -- Symmetricom, Inc. (Nasdaq:SYMM), a worldwide leader in precise time and frequency products and services, today announced the 20th anniversary of its Active Hydrogen Maser MHM 2010(tm), one of the world's finest commercially available active hydrogen maser and offering the highest in atomic frequency standard performance and reliability. The first commercially available maser shipped from Symmetricom in 1985, and since that time, 85 have been deployed throughout the world to institutions at the forefront of time and frequency excellence, including the U.S. Naval Observatory (USNO), U.S. National Radio Astronomy Observatory, U.S. National Institute of Standards and Technology (NIST), National Physical Laboratory (NPL) and many others. The company also announced a new extended 7-year warranty for the maser, emphasizing the proven, field-tested reliability for the most stable, longest life hydrogen maser in the MHM2010 product family.
"Symmetricom's Hydrogen Maser with stand-alone cavity auto-tuning enables it to deliver long-term stability normally only attributed to the most stable of cesium atomic standards," commented Doug Lowrie, product marketing manager at Symmetricom. "With an estimated life in excess of twenty years and a track record for reliability and performance that has been proven over the decades of successful operation, we now translate this tried and true performance by extending our standard warranty to 7 years. This is unmatched in the industry."
As one of Symmetricom's largest customers, the USNO maintains the Master Clock for the United States. The Department of Defense, together with NIST, provides the official time for the nation. The USNO atomic clock timescale utilizes a dozen Symmetricom hydrogen masers. Each maser is a critical element for precise time determination and dissemination. The exceptional reliability of the MHM2010 helps ensure the robustness of this mission critical system.
The MHM2010 Hydrogen Maser contains a number of features that contribute to the excellent performance over other units, including:
- Patented Magnetic Quadrapole providing superior atomic beam Focusing
- Very low Hydrogen usage (less than 0.01 mole per year) for extended maintenance-free operation
- Cavity Auto-Tuning
- Proprietary Teflon coating technique eliminates re-coating requirement, extending maintenance free life
Each MHM 2010 is manufactured to the most precise quality standards and carefully checked at each stage to insure a top quality product. Once built, the units are subjected to extensive performance testing, verifying all aspects of operation. Before shipment, each unit goes through rigorous testing and performance monitoring to insure that the unit meets or exceeds all specifications.
For demanding applications in radioastronomy, fundamental research and the realization of international timescales, the short and medium term stability of Symmetricom's hydrogen maser is unsurpassed, with less than 2 parts in 10E+13 at 1 second. Long term drift rates typically exceed less than one part in 10E+16 per day.
