Abstract	In this paper, we describe a novel vector measurement system for the characterization of Gaussian beams and present test results for mm-wave, 211-275 GHz, receiver optics alignment. The measurement setup allows a simpler design without any PLLs and employs a combination of a single frequency source, comb-generator, and direct multiplication LO and signal sources. The system takes advantage of different harmonics to generate the required RF and LO signals yielding the desired IF frequency while obtaining perfect phase-coherence and initial phase-noise cancellation. One of the additional advantages of the suggested measuring scheme is that it allows such design that it has the potential to cover different mm and sub-mm bands by only replacing two filters and the LO multiplication unit. For example, we plan to use the same setup, with mentioned modifications, for the frequency bands 275-370 GHz and 385-500 GHz.
