Abstract
A six-port network for characterizing a microwave or R.F. device includes a signal source (1) capable of generating three signals of the same frequency but relative phase differences, and combines each of the signals with a signal reflected or transmitted by the device. Two three-phase sources may be used in a dual six-port network device.
