A Direct-Reading Six-DECADE Precision Frequency Generator

摘要

The development of a direct-reading six-decade frequency genera-tor to be used in conjunction with a previously reported direct-reading frequency meter has been satisfactorily completed. This new frequency generator has been made with unitized construction to overall dimen¬sions of 12-3/4 x 14-1/2 x 5-3/4 in., or 0.615 cu ft, and utilizes minia¬ture tubes, but the size could be reduced appreciably in a subsequent model. Each of 6 plug-in decade chassis has 3 tubes, for a total of 18 tubes, and the reference-frequency section, composed of 11 small plug-in chassis, has a total of 29 tubes. In the next model the number of tubes could be reduced to 6 and 20, respectively.
