Development of a Highly Stable Crystal Controlled Oscillator-Exciter

Abstract

To meet the need for standardized crystal oscillator, a highly stable circuit has been developed for use from 2 to 6 megacycles. The circuit consists of a Pierce-Electron Coupled Oscillator of special design, followed by two stages of amplification. Under the combined effects of extreme temperature variation, supply and cathode heater voltage variation, stabilization, tube change and change in loading, the stability is 0.0012 percent or better. This permits a crystal unit tolerance of 0.0013 percent, if a 0.0025 percent overall tolerance limit is to be attained.
