Selection and Use of Precise Frequency and Time Systems


image of Selection and Use of Precise Frequency and Time Systems

This Handbook consists of ten chapters which describe basic concepts, frequency and time sources, measurement techniques, characteristics of various frequency standards, operational experience, problems and future prospects. The contents include detailed explanations and many references that can be consulted for additional details.



Introduction to the Handbook

Over the last few decades atomic clocks have moved from laboratory novelties to large scale usage. The improvement in quartz oscillator technology and in satellite timing systems has augmented the decades of improvement in atomic clocks. Navigation, communication and power systems have all benefited greatly from these improvements. Precise timing has moved from a novelty to a necessity, and we are seeing many other applications benefit as well. One of the reasons being that frequency is not only the most accurate measurement known to man, but it is also the most cost effective of the metrology units. Hence, many applications depend on precise timing elements.
