Maintenance of HP 5071A Primary Frequency Standards at USNO

Abstract

The US. Naval Observatory (USNO) has been operating Hewlett-Packard model 5071A cesium-beam frequency standards for over five years. During that period, there have been a variety of failures and these devices have shown frequency and phase changes. The HP 5071A model primary frequency standard offers a very useful troubleshooting tool by outputting the status of 22 different operating parameters. This paper will present an explanation of the parameters and show any correlation of them with the time, frequency, and environmental changes. This paper will also offer some indicators to predict future device problems.
