Frequency standard — A frequency standard is a stable oscillator used for frequency calibration or reference. A frequency standard generates a fundamental frequency with a high degree of accuracy and precision. Harmonics of this fundamental frequency are used to… … Wikipedia
Secondary frequency standard — In telecommunications, a secondary frequency standard is a frequency standard that does not have inherent accuracy, and therefore must be calibrated against a primary frequency standard. Secondary standards include crystal oscillators and… … Wikipedia
Rubidium standard — A rubidium standard is a frequency standard in which a specified hyperfine transition of electrons in rubidium 87 atoms is used to control the output frequency. A rubidium standard consists of a gas cell, which has an inherent long term… … Wikipedia
