ABSTRACT:
In one embodiment, a method of automatically calibrating a network analyzer for measuring devices under test (DUTs) using a test fixture comprises generating a stimulus signal on a respective port that is coupled to the test fixture; measuring reflection of the stimulus signal on the respective port to generate measurement data, wherein the measurement data reflects a phase response of the test fixture; processing the measurement data to compensate for ripples generated by impedance mismatch at a coupling associated with the network analyzer and the test fixture; and adjusting a port extension setting of the network analyzer according to the processing.
