Methods and apparatus for calibrating a vector network analyzer (VNA) and characterizing a device under test. In one example, a device fixture including a pair of embedded device adapters provides an interface between a device under test (DUT) with non-coaxial connectors and the coaxial connectors of the VNA, and moves the calibration reference plane from the coaxial connectors of the VNA to a DUT reference plane at the leads/connectors of the DUT. A through fixture having a pair of similar through adapters 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.
