A full reversing millimeter test set comprising a pair of test head assemblies which are connected to an analyzer by means of coaxial cables enclosed within a sheath. Microwave signals are sent to the test head assemblies and therein frequency-multiplied so as to provide the necessary millimeter test signals required for testing microwave devices in the W band of 75-110 GHz. By placing the millimeter wave components in the test head assemblies, the phase distortions which would otherwise be encountered in flexing or movement of the interconnecting coaxial cables and the bulk, signal loss and phase distortions associated with long waveguide are eliminated.
