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. Basic concepts and definitions, time prediction, confidence limits when estimating the variance from a finite data set, and confidence limits for frequency domain measures are covered in the annexes. The annexes also cover translation between the frequency-domain and time-domain measures, examples on how to calculate the time-domain measures of frequency fluctuations, and an extensive bibliography of the relevant literature. Systematic instabilities, such as environmental effects and aging, are discussed in IEEE Std 1193-1994 .

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. Basic concepts and definitions, time prediction, confidence limits when estimating the variance from a finite data set, and confidence limits for frequency domain measures are covered in the annexes. The annexes also cover translation between the frequency-domain and time-domain measures, examples on how to calculate the time-domain measures of frequency fluctuations, and an extensive bibliography of the relevant literature. Systematic instabilities, such as environmental effects and aging, are discussed in IEEE Std 1193-1994 .

Systematic instabilities, such as environmental effects and aging, are discussed in IEEE Std 1193™-2003.<br />\n
          The purpose is to update the existing standard on physical quantities for frequency and time metrology. New measures (quantities) of frequency stability need to be added to the document and some sections defining quantities need to be expanded.

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. Basic concepts and definitions, time prediction, confidence limits when estimating the variance from a finite data set, and confidence limits for frequency domain measures are covered in the annexes. The annexes also cover translation between the frequency-domain and time-domain measures, examples on how to calculate the time-domain measures of frequency fluctuations, and an extensive bibliography of the relevant literature. Systematic instabilities, such as environmental effects and aging, are discussed in IEEE Std 1193-1994 .
