Description

IEEE P1139 – IEEE Approved Draft Standard Definitions of Physical Quantities for Fundamental Frequency and Time Metrology–Random Instabilities

Revision Standard – Active – Draft.Methods of describing random instabilities of importance to frequency and time metrology are covered. Quantities covered include frequency, amplitude, and phase instabilities; spectral densities of frequency, amplitude, and phase fluctuations; and time-domain deviations of frequency fluctuations. In addition, recommendations are made for the reporting of measurements of frequency, amplitude, and phase instabilities, especially in regard to the recording of experimental parameters, experimental conditions, and calculation techniques.
