5071A Primary Frequency Standard Symmetricom's 5071A primary frequency standard delivers unsurpassed accuracy, stability and reliability for the most demanding laboratory and field applications. Metrology and Calibration Labs The 5071 offers exceptional frequency stability which is a key specification that directly effects a laboratory's ability to deliver timekeeping and calibration services to its clients. With a stability specification for 30-day averaging time, the 5071A can keep extremely predictable time and phase for long periods. Further, the 5071A can be used for long-term averaging of noisy signals such as GPS. Performance suited to advanced communications and tracking systems Stable frequency generation and frequency flexibility are required to transmit and receive signals properly between ground terminals and communication satellites. The 5071A's state-of-the art technology produces offset and primary frequencies with the same guaranteed stability.
Cs4000 Cesium Frequency Standard The Symmetricom Cs4000 is a new cesium frequency standard platform that provides exceptional performance in a configurable 3U rack mount chassis. The Cs4000 is designed for high precision timing and frequency applications requiring high stability, low noise RF and 1PPS reference signals. Symmetricom's advanced Cesium III digital technology is the engine that drives this exceptional performance. The Cs4000 includes a new color front panel Graphical User Interface (GUI) that provides easy to use monitoring and control of the instrument. All functional control of the cesium and optional output cards are managed via the front panel GUI. The GUI is a touch panel LCD screen that provides easy at a glance access to cesium health, control and configuration data. Remotely, you now have two methods of interfacing with the Cs4000. A new Ethernet interface provides monitoring capability via an embedded web page server. Both static IP and DHCP are supported. The Cs4000 also provides an RS-232 port that allows the user comprehensive monitor and control access via ASCII commands or via Symmetricom's Monitor 3 windows based utility program. The Cs4000 meets the challenges of laboratory standards, satcom terminals, mobile communications systems and a wide variety of test and measurement applications.
CsIII Cesium Frequency Standard Symmetricom's CsIII™ is a lightweight, compact, economical cesium frequency standard. The technology developed for the CsIII is an evolutionary step forward in the quest for higher stability, lower phase noise and longer life. An ever-increasing base of demanding users in communications, timing, synchronisation and other applications take advantage of this performance. Packaged in a 2U, 19" rack mounted chassis; the CsIII weighs less than 30 lbs. Standard features include 5 and 10Mhz sine wave outputs, a 1 PPS output and an RS-232 interface used to monitor and control the unit. Optional T1/E1 telecom outputs and a portability kit are also available. The portability kit replaces the rack mounting brackets with a movable handle and hard shell carrying case making it ideal as a remote calibration standard.
