Symmetricom Announces Fourth-Generation Cesium Frequency Standard; New Platform Provides Superior Levels of Accuracy and Stability.Business Editors/High-Tech Writers SANTA ROSA Santa Rosa, city, Argentina Santa Rosa, city (1991 pop. 80,629), capital of La Pampa prov., central Argentina. It is a modern city and road junction surrounded by a rich agricultural and cattle-raising area. , Calif.--(BUSINESS WIRE)--July 8, 2003 Symmetricom's (Nasdaq:SYMM SYMM Synchronized Multimedia (W3C Working Group) ) Timing Test and Measurement division today announced the introduction of its fourth generation Cesium cesium (sē`zēəm) [Lat.,=bluish gray], a metallic chemical element; symbol Cs; at. no. 55; at. wt. 132.9054; m.p. 28.4°C;; b.p. 669.3°C;; sp. gr. 1.873 at 20°C;; valence +1. frequency standard platform, the Symmetricom Cs4000. The Cs4000 is ideally suited for and meets the stringent requirements of laboratory standards, satellite communications terminals, military communications Military communications, or Signals, is a field of military activities, tactics and equipment dealing with communications. First of all, military communications are battlefield (combat) communications, including intercommunication with a higher command or country's and a wide variety of metrology, test and measurement applications. 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 National Institute of Standards and Technology, governmental agency within the U.S. Dept. of Commerce with the mission of "working with industry to develop and apply technology, measurements, and standards" in the national interest. ), it acts as a highly accurate master clock that provides signals in timing systems and for international timescales. "The Cs4000 will provide our customers with a versatile cesium instrument that delivers best in class performance," says Lisa Withers withers the region over the backline where the neck joins the thorax and where the dorsal margins of the scapulae lie just below the skin. fistulous withers see fistulous withers. , Symmetricom executive vice president and general manager. "Standalone reliability, ease of use and ease of installation make the Cs4000 ideal for our diverse customer base. As we push our technology forward, we are able to continue to provide even greater performance, higher reliability and lower costs to our customers." Advanced Cesium III digital technology is at the core of the Cs4000 and is a result of Symmetricom's ongoing research and development efforts which have led to performance improvements in long term stability and accuracy, key elements for this class of instruments. The accuracy and stability achievable with this technology is commensurate with any cesium standard available in the world today. "The Cs4000 design is an evolutionary step in our development of more precise and more stable atomic frequency standards," said Dr. R. Michael Garvey, chief technical officer of Symmetricom's Technology Realization Center. "We have improved our microwave interrogation interrogation In criminal law, process of formally and systematically questioning a suspect in order to elicit incriminating responses. The process is largely outside the governance of law, though in the U.S. of the atomic resonance, and we have incorporated adaptive software algorithms in a reliable, cost-effective platform designed to provide a long service life. Our design team has much to be proud of." The Cs4000 base configuration provides a well-equipped and versatile array of precision signal outputs that include 100kHz, 1MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. , 5MHz, 10MHz and 1 pulse per second A Pulse per second (PPS) is an electrical signal that very precisely indicates the start of a second. PPS signals are output by various types of precision clock, including some models of GPS receivers. (PPS (Packets Per Second) The measurement of activity in a local area network (LAN). In LANs such as Ethernet, Token Ring and FDDI, as well as the Internet, data is broken up and transmitted in packets (frames), each with a source and destination address. ). It can be configured for standard frequency stability performance or high frequency stability performance. Other standard features include remote interface with Symmetricom's custom software for monitoring and controlling the instrument, as well as redundant AC and DC power inputs. The Cs4000 also has an internal battery back-up that can power the unit for up to an hour in the event of a main power loss, providing a third layer of power redundancy. Finally, the back panel and internal chassis structure include areas designated for customer-defined special options.
