Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
1139-1999
IEEE Standard Definitions of Physical Quantities for Fundamental Frequency and Time Metrology-Random Instabilities
Methods of describing random instabilities of importance to frequency and time metrology is covered in this standard. Quantities covered include frequency, amplitude, and phase instabilities; spectral densities of frequency, amplitude, and phase fluctuations; and time-domain variances 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.
1139-1999
Standard Definitions of Physical Quantities for Fundamental Frequency and Time Metrology - Random Instabilities
Affects all documents dealing with the reporting or specification of time and frequency measurements and instrumentation.
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
1139-1988
IEEE Standard Definitions of Physical Quantities for Fundamental Frequency and Time Metrology
Methods of describing random instabilities of importance to frequency and time metrology is covered in this standard. Quantities covered include frequency, amplitude, and phase instabilities; spectral densities of frequency, amplitude, and phase fluctuations; and time-domain variances 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.
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
1139-2008
IEEE Standard Definitions of Physical Quantities for Fundamental Frequency and Time Metrology--Random Instabilities
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.
1193-2003
IEEE Guide for Measurement of Environmental Sensitivities of Standard Frequency Generators
Standard frequency generators that include all atomic frequency standards and precision quartz crystal oscillators are addressed.
