The General Radio 1607-A Transfer-Function and Immittance Bridge was introduced in Catalog P (1959) and remained available through Catalog U (1970).
The Type 1607-A is a null-type instrument designed to measure transfer-functions and immittance at frequencies from 25 MHz to 1.2 GHz using separate indicator units. It can measure passive devices as well as active devices such as semiconductors and vacuum tubes.
An example transfer-function measurement would be the alpha of a transistor at 500 MHz or the immittance of a resistor or network at 1 GHz. Other uses are the measurement of reflection coefficient and VSWR of antennas and transmission lines.
As a bridge instrument, the 1607-A requires an oscillator and DNT or heterodyne type detector operating at the frequency of interest. The theory of operation of the Type 1607-A is similar to the 1602-B.
Specifications
