IEEE Standard Definitions of Physical Quantities for Fundamental Frequency and Time Metrology–Random Instabilities
Published By | Publication Date | Number of Pages |
IEEE | 2009 | 45 |
Revision Standard – Active. Methods of describing random instabilities of importance to frequency and time metrology are covered in this standard. 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 as regards the recording of experimental parameters, experimental conditions, and calculation techniques.
