Abstract: The disclosure relates to an apparatus and a method for vector scattering parameter (s-parameter) measurements, and more particularly, to an apparatus and a method for providing a simple, low cost solution for tests requiring vector s-parameter measurements. The apparatus includes a source which provides an input signal, a divider which splits the input signal to a reference signal and a testing signal, a phase shifter which shifts the reference signal by a first phase and outputs a phase shifted signal, a device under test (DUT) which shifts the testing signal by a second phase and outputs a DUT shifted signal, a combiner which combines the phase shifted signal and the DUT shifted signal into a combined signal, and a detector which detects a product of the phase shifted signal and the DUT shifted signal.
