Portable Real-Time Clock.

Abstract

In June of 1978, Frequency Electronics was awarded a contract to perform the necessary research and development to advance the state of the art in Cesium beam tube technology and applications to a point that would make it feasible to design and fabricate a portable Cesium Beam Frequency Standard having performance characteristics equivalent to that of the existing non-portable units. The current production model of the Cesium Beam Standard is Model FE-5440A which is presently used in the 616A program and other airborne, shipboard, and ground support systems. The frequency and time signals produced by the Cesium Standard are extremely accurate with tolerances for accuracy and stability being on the order of several parts per 10 to the minus 11th power.
