General Radio 1602B

The 1602B UHF Admittance Meter is a null-type instrument that measures complex impedance and admittance in coaxial systems and, as a reflectometer, will determine SWR, impedance magnitude, and reflection coefficient magnitude. The unit covers the frequency of 20MHz to 1.5GHz. Direct-reading conductance and susceptance. Can also be used to adjust a network to a predetermined admittance, to match one network to another, and to match antennas and other networks to 50-ohm circuits.
