Frequency Stability measurements are accessed manually by pressing the front-panel Measurement selection key. NOTE In some test set applications it is necessary to select an analog System Type (for example, AMPS) or an analog Operating Mode (for example, AVC Test or CW) to access the Frequency Stability measurement. Handbook of Frequency Stability Analysis W.J. Riley Under contract with: Time and Frequency Division Physics Laboratory National Institute of Standards and Technology Broadway Boulder, CO July U.S. Department of Commerce Carlos M. Gutierrez, Secretary National Institute of Standards and Technology James M. Turner, Deputy Director. Yoshimura, ). Box-Jenkins-type models have been applied for the interpretation of frequency stability measurements [Barnes, ; Percival, and reviewed by Winkler ). Lindsey and Chie  have generalized the r.m.s. fractional frequency deviation and the two-sample. The analyzer frequency accuracy is based on an internal 10 MHz frequency oscillator. See Technical Specifications for stability and aging specifications. If your measurement application requires better frequency accuracy and stability, you can override the internal frequency standard and provide your own high-stability external frequency source.

Programming a Frequency Stability Measurement. Janu This section provides an example of how to make Frequency Stability measurements via GPIB.. The following program example assumes that a signal within the measurement range in connected to the RF IN/OUT connector (see Input Signal Requirements)..

The Allan variance (AVAR), also known as two-sample variance, is a measure of frequency stability in clocks, oscillators and amplifiers, named after David W. Allan and expressed mathematically as ().The Allan deviation (ADEV), also known as sigma-tau, is the square root of the Allan variance, ().. The M-sample variance is a measure of frequency stability using M . Handbook of Frequency Stability Analysis W.J.

Model-free data interpretation methods involve analyzing measurement data and tracking changes in a structure without use of geometrical and material information. This section describes two model-free data interpretation methods, MPCA and RRA. Cited by: Radio Frequency Performance Parameters – Frequency Stability The Frequency Stability of a Transmitter is a measure of how close the actual frequency transmitted is to the wanted. Frequency Stability is directly determined by the Crystal Oscillator, as all frequencies produced in the Synthesizer are locked to this reference.
