Vibration Compensation of the Seektalk Rubidium Oscillator,

Abstract

In the past, atomic oscillators have not been designed to operate in the presence of severe vibration. In recent years some have been designed to allow some vibration but now they are being called on to accommodate sinusoidal vibration up to 14 'g's' peak and random vibration spectra up to 0.5g2/Hz or more. These levels perhaps required only survival a few years ago, but are now the operating environment of atomic oscillators. Efforts to improve the acceleration-susceptibility of the rubidium oscillator have been successful in the rubidium portion, but vibration-induced sidebands in the quartz-crystal oscillator cause a great deal of difficulty when multiplied to 6.8 GHz to interrogate the rubidium. Of course, the quartz oscillator frequency is also the output available to the user who has similar difficulties in multiplying to UHF or microwave.
