Cesium Frequency Standard - 5071A - Symmetricom - #1

Text version of the page

5071A Primary Frequency Standard The 5071A primary frequency standard has the accuracy and stability you need for both laboratory and field applications. A stability specification for 30-day averaging time means the 5071A will 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. The 5071A is easy to use. No more manual start-up steps or complicated adjustments— everything is automatic. A logical menu structure simplifies front panel operations, selections, and status reporting. Remote control features tailor the 5071A for complete operation and manageability in virtually any location. The 5071A is a direct descendant of and replacement for the veteran 5060A, 5061A and 5061B cesium standards. This innovative product is the result of more than 35 years of experience in the precision frequency standard business.

A standard’s accuracy and reliability determine the quality of service these timekeeping labs provide. Of even greater concern is the stability of a standard. Stability directly affects a laboratory’s ability to deliver timekeeping and calibration services to its clients. The 5071A offers exceptional stability and is the first cesium standard to specify its stability for averaging times longer than one day. The instrument takes into account environmental conditions that can heavily influence a cesium standard’s long-term stability. Digital electronics continuously monitor and optimize the instrument’s operating parameters. TIMING, TEST & MEASUREMENT 5071A Primary Frequency Standard
