Selecting a Primary Frequency Standard for a Calibration

rubidium frequency slowly over time Manufacturers typically specify the aging rate of rubidiums as 510-11 per month but this specification is often conservative as the frequency of a well behaved rubidium standard typically changes by less than 110-11 over the course of a month [6] Even so the frequency change can still exceed 1Get price
