Methods and apparatus for calibrating a vector network analyzer (VNA) and characterizing a device under test. In one example, a device fixture (110) including a pair of embedded device adapters (150,155) provides an interface between a device under test (DUT) with non-coaxial connectors and the coaxial connectors of the VNA (170), and moves the calibration reference plane from the coaxial connectors of the VNA to a DUT reference plane (190a,190b) at the leads/connectors of the DUT. A through fixture (510) having a pair of similar through adapters (520,525) is used to establish the DUT reference plane and to facilitate characterizing the device adapters such that they can be de-embedded from measurements of the device fixture.
