Wave Meter Class C No 1 Crystal Unit and Vibrator Power Supply

General description

Purpose and facilities


The Wavemeter, Class C, No. 1 is a portable heterodyne wavemeter for use with field wireless sets for adjusting the senders and receivers to particular frequencies and for checking the frequency calibration of these sets.

The overall accuracy (±0.1 %) without a crystal unit is not sufficiently high for it to be used as a check of absolute frequency, so that, where inter-group working is required, the wavemeters checking the frequencies of each group should be checked against a crystal unit or mutually against each other.
