1606-A
The General Radio 1606-A RF Bridge was introduced in Catalog O (1956) and remained available through Catalog S (1965).
The Type 1606-A is null-type instrument for measuring relatively low impedances. Its frequency range is 400 kHz to 60 MHz but that can be expanded with reduced accuracy. Any oscillator delivering 0.1 to 10 V at the frequency of interest can be used as a generator.
The detector often used is a radio receiver of the proper frequency with adjustable gain and AVC. The recommended detectors are of the heterodyne or DNT type. Applications for the 1606-A include analysis of antennas, components and networks of relatively low impedance.
