Laboratory NPL, New Delhi, these rubidium standards are transported to NPL for frequency calibration. The method of frequency calibration used at NPL consists of tracking the phase of the 5 MHz output of the rubidium device relative to the frequency standard at NPL for about 10 days. The slope of this variation then gives the frequency offset.

Laboratory NPL, New Delhi, these rubidium standards are transported to NPL for frequency calibration. The method of frequency calibration used at NPL consists of tracking the phase of the 5 MHz output of the rubidium device relative to the frequency standard at NPL for about 10 days. The slope of this variation then gives the frequency offset.
