The 2Z-073 from Maury Microwave are 2.92 mm VNA Calibration Kits that operate from DC to 40 GHz. These kits support Fixed Load SOLT and Characterized Device (CD) SOLT calibration methods. They are designed for 1-port and 2-port VNA calibration validation for well-matched and mismatched DUTs by comparing the S-parameters of user-characterized and factory-characterized verification standards, with or without measured uncertainty boundaries. The precision 2.92mm connectors on the components in these kits are miniature, instrument grade, air-interface connectors that comply with IEEE standard 287 general precision connector, instrument grade GPC2.92.
