The measurement of voltage at centimetre wavelengths

The paper describes apparatus for the measurement of voltage at centimetre wavelengths. The equipment includes a gold-leaf electroscope for establishing a standard of voltage; test connectors by means of which connection is made to the circuit to be measured; broad-band crystal holders by which the voltage is actually measured; and amplifying equipment for use with the crystal holders when small voltages have to be measured. Two sets of equipment are described, one for the range 8.5 to 11.0 cm and the other for the range 3.0 to 3.5 cm.
