          Revision Standard - Active.<br />\n
          Guidelines for the measurement and specification of environmental sensitivities of frequency standards and references are presented, including considerations specific to a variety of atomic and mechanical frequency sources.<br />\n
          \t\t\t\t<br />\n
          The basic principle governing the physical measurement of time is demarcation of equal time intervals by observation of a repeating process such as oscillations of a quartz crystal or of the electromagnetic field that excites a transition in an atom (e.g., cesium). Such a repeating periodic process can be used as a frequency standard. Frequency standards include atomic frequency standards, laser and cavity resonators, and mechanical oscillators [including, e.g., quartz, dielectric resonator (DROs), cryogenic sapphire, micro-electro-mechanical system (MEMS), and thin-film resonator (TFR) oscillators]. All types of frequency standards can be influenced by environmental sensitivities. The following three different areas of concern exist for the environmental testing and specifications of frequency standards: a) Fitness of a frequency standard for actual user needs in specific environments (tests attempt to mimic the anticipated environments) b) Characterization of a frequency standard's environmental sensitivities (tests attempt to provide distinct sensitivity coefficients for variations in independent environmental parameters) c) Reliability and survival (tests attempt to stress the unit by either going to extremes of operating ranges or by repeated application of stimuli, e.g., cycling) This document puts emphasis on item b). It provides guidance and a conceptual framework rather than a prescription of procedures that must be followed. It emphasizes proper methodology and practice and cautions against pitfalls. In summary, this IEEE guide is not a specification document but a resource document for deriving specification statements. This document often refers to the influence of random frequency fluctuations on the measurement and characterization of environmental sensitivities. Readers unfamiliar with frequency fluctuations, phase noise, and Allan deviations should refer to IEEE Std 1139.<br />\n
          This document describes the nature of the environmental effects, as well as the test methods to evaluate, quantify, and report (i.e., in specifications) the sensitivity of a frequency standard's output frequency to environmental influences such as magnetic fields, atmospheric pressure, humidity, vibration, acceleration, temperature, ionizing radiation, and intermittent operation. Its primary purpose is to aid in defining specifications and to verify specified performance through measurement. In addition, this document will help to assure consistency and repeatability of environmental sensitivity measurements, as well as the use of consistent methods across the various segments of the time and frequency community.

Frequency standards include atomic frequency standards, laser and cavity resonators, and mechanical oscillators [including, e.g., quartz, dielectric resonator (DROs), cryogenic sapphire, micro-electro-mechanical system (MEMS), and thin-film resonator (TFR) oscillators]. All types of frequency standards can be influenced by environmental sensitivities. The following three different areas of concern exist for the environmental testing and specifications of frequency standards: a) Fitness of a frequency standard for actual user needs in specific environments (tests attempt to mimic the anticipated environments) b) Characterization of a frequency standard's environmental sensitivities (tests attempt to provide distinct sensitivity coefficients for variations in independent environmental parameters) c) Reliability and survival (tests attempt to stress the unit by either going to extremes of operating ranges or by repeated application of stimuli, e.g., cycling) This document puts emphasis on item b). It provides guidance and a conceptual framework rather than a prescription of procedures that must be followed. It emphasizes proper methodology and practice and cautions against pitfalls. In summary, this IEEE guide is not a specification document but a resource document for deriving specification statements. This document often refers to the influence of random frequency fluctuations on the measurement and characterization of environmental sensitivities. Readers unfamiliar with frequency fluctuations, phase noise, and Allan deviations should refer to IEEE Std 1139.<br />\n
          This document describes the nature of the environmental effects, as well as the test methods to evaluate, quantify, and report (i.e., in specifications) the sensitivity of a frequency standard's output frequency to environmental influences such as magnetic fields, atmospheric pressure, humidity, vibration, acceleration, temperature, ionizing radiation, and intermittent operation. Its primary purpose is to aid in defining specifications and to verify specified performance through measurement. In addition, this document will help to assure consistency and repeatability of environmental sensitivity measurements, as well as the use of consistent methods across the various segments of the time and frequency community.

          Revision Standard - Inactive-Reserved.<br />\n
          Standard frequency generators that include all atomic frequency standards and precision quartz crystal oscillators are addressed.<br />\n
          \t\t\t\t<br />\n
          This project is a revision of the existing guide for measurements of environmental sensitivities of standard frequency generators. It includes effects and metrology of acceleration; temperature, humidity, and pressure; electrical and magnetic fields; ionizing and particle radiation; and aging, warm-up time and retrace.<br />\n
          The purpose is to update effects and metrology of environmental conditions of relevance to frequency generators. The intended audience are manufacturers and users of time and frequency technology. Benefits include information on environmental effects, guide in the measurements of these effects, and aid with the specifications of generators.

          Revision Standard - Active.<br />\n
          Guidelines for the measurement and specification of environmental sensitivities of frequency standards and references are presented, including considerations specific to a variety of atomic and mechanical frequency sources.<br />\n
          \t\t\t\t<br />\n
          The basic principle governing the physical measurement of time is demarcation of equal time intervals by observation of a repeating process such as oscillations of a quartz crystal or of the electromagnetic field that excites a transition in an atom (e.g., cesium). Such a repeating periodic process can be used as a frequency standard. Frequency standards include atomic frequency standards, laser and cavity resonators, and mechanical oscillators [including, e.g., quartz, dielectric resonator (DROs), cryogenic sapphire, micro-electro-mechanical system (MEMS), and thin-film resonator (TFR) oscillators]. All types of frequency standards can be influenced by environmental sensitivities. The following three different areas of concern exist for the environmental testing and specifications of frequency standards: a) Fitness of a frequency standard for actual user needs in specific environments (tests attempt to mimic the anticipated environments) b) Characterization of a frequency standard's environmental sensitivities (tests attempt to provide distinct sensitivity coefficients for variations in independent environmental parameters) c) Reliability and survival (tests attempt to stress the unit by either going to extremes of operating ranges or by repeated application of stimuli, e.g., cycling) This document puts emphasis on item b). It provides guidance and a conceptual framework rather than a prescription of procedures that must be followed. It emphasizes proper methodology and practice and cautions against pitfalls. In summary, this IEEE guide is not a specification document but a resource document for deriving specification statements. This document often refers to the influence of random frequency fluctuations on the measurement and characterization of environmental sensitivities. Readers unfamiliar with frequency fluctuations, phase noise, and Allan deviations should refer to IEEE Std 1139.<br />\n
          This document describes the nature of the environmental effects, as well as the test methods to evaluate, quantify, and report (i.e., in specifications) the sensitivity of a frequency standard's output frequency to environmental influences such as magnetic fields, atmospheric pressure, humidity, vibration, acceleration, temperature, ionizing radiation, and intermittent operation. Its primary purpose is to aid in defining specifications and to verify specified performance through measurement. In addition, this document will help to assure consistency and repeatability of environmental sensitivity measurements, as well as the use of consistent methods across the various segments of the time and frequency community.

          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.

          This standard covers the fundamental metrology for describing random instabilities of importance to frequency and time metrology. Quantities covered include frequency, amplitude, and phase instabilities; spectral densities of frequency, amplitude, and phase fluctuations; and time-domain deviations of frequency and phase fluctuations. In addition, recommendations are made for the reporting of measurements of frequency, amplitude, and phase instabilities, especially with regard to calculation techniques, but also including experimental parameters. The annexes cover basic concepts and definitions, time prediction, and confidence limits when estimating deviations and spectral densities from a finite data set. The annexes also cover translation between the frequency domain and time domain instability measures, examples on how to calculate the time-domain measures of frequency and phase fluctuations, and an extensive bibliography of the relevant literature. Systematic instabilities, such as environmental effects and aging, are discussed in IEEE Std 1193 [B39]<br />\n
          This standard defines and formalizes the techniques and physical quantities used to measure and characterize frequency, phase, and amplitude instabilities in time and frequency instruments and systems.
