Excerpt from The Measurement of Frequency and Frequency Stability of Precision Oscillators The specification and performance of precision oscillators is a very important topic to the owners and users of these oscillators. This paper presents at the tutorial level some convenient methods of measuring the frequencies and/or the frequency stabilities of precision oscillators - giving advantages and disadvantages of these methods. Conducting such measurements, of course, gives additional understanding into the performance of the given pair of oscillators involved. Further it is shown that by processing the data from the frequency measurements in certain ways, one may be able to state more general characteristics of the oscillators being measured. The goal in this regard is to allow the comparisons of different manufacturers' specifications and more importantly to help assess whether these oscillators will meet the standard of performance the user may have in'a particular application. The methods employed for measuring frequency are designed for state - of the-art oscillators, and an effort has been made to allow for fairly simple, inexpensive, and/or commonly available components to be used in the measurement systems. The method for measuring frequency stability is basically that recommended by the ieee subcommittee on Frequency Stability of the Technical Committee on Frequency and Time of the ieee Group on Instrumentation Measurement. Keywords: Accurate frequency measurement; Accurate time measurement; Frequency; Frequency stability; Frequency stability analysis; Models of frequency stability; Picosecond time difference measurements.
