Abstract

Digitally-controlled tracking impedances and an automatic standing wave ratio measuring instrument employing digitally-controlled tracking impedances to cause a voltage representing the forward voltage in a radio frequency transmission system to track a fixed voltage and to output a voltage with which the standing wave ratio can be directly displayed independently of the power characteristics of the transmission system.
