Characterized Device (CD) Calibration Verification Kits are designed for 1-port and 2-port VNA calibration validation for well-matched and mismatched DUTs. Each kit comes with individually characterized verification standards and is used for calibration validation by comparing the S-parameters of the appropriate verification standard measured by the user and the S-parameters measured at the factory. When combined with Insight™, users will be able to use overlapping uncertainty boundaries to validate a VNA calibration with increased confidence. Verification kits are available with Type N, 7mm, 3.5mm, 2.92mm and 2.4mm connectors.
