ABSTRACT:
A method and apparatus for measuring the voltage standing wave ratio on a radio frequency transmission line. The bandwidth of radio frequency signals over which the apparatus accurately operates is improved by the use of a filter to unload terminating resistors at low frequencies and by the use of an inductive element in the measuring circuit to compensate for phase lag induced by elements of the measuring circuit.
