Abstract
The design of both narrow band high stabilization and broad band lower stabilization spectrum line discriminators is developed in a generalized form applicable to various spectrum lines and cavity designs. Comparison with experiment is made for two broad band discriminators utilizing the NH3 3,3‐absorption line at 23,870 megacycles as the frequency determining element. These discriminators used with an amplifier of 2000 gain, reduce drifts by factors of 250 and 1000, respectively, compared to an unstabilized tube.Keywords
