Frequency and Timing System at the National Institute for Standards (NIS)

S. Samuel

Abstract: The National Institute for Standards (NLS), 1s charged with the responsibility of establishing and maintaining the nations standards of physical measurements and providing means for the effective utilization. Time and Frequency division of Egypt makes the international comparison to relate NIS frequency standard to UTC. Traceable frequency calibrations to NIS of standard clocks kept in other Egyptian scientific organizations, military and industrial laboratories are provided by means of daily television measurements and common-view monitoring of Loran-C signals by the user and by NIS. This paper describes the Frequency and Tinning system used at the NIS and the methods of comparing NIS frequency standard with UTC. Diagrams and specifications of today's system and plans for future work will be presented.
