    摘要: A method is disclosed for improving the effective frequency stability of a frequency reference source, wherein an algorithm utilizing parameters determined from frequency and temperature sensing measurements of the source or a similar source over a number of temperature excursions of different magnitude is used in conjunction with temperature history to correct the frequency reference output accounting for effects of hysteresis in the frequency-temperature characteristic of the source. Devices and manufacturing systems are also claimed.
