Agilent / Keysight 85033E Calibration Kit, DC to 9 GHz, 3.5 mm

The Keysight 85033E is a precision calibration kit for 3.5 mm connectors, enabling accurate network analyzer calibration from DC to 9 GHz. This kit maintains measurement integrity across RF and microwave frequencies by supplying metrology-grade calibration standards - offset opens, shorts, and 50 ohm loads - each engineered for repeatable connections and minimal drift. The single-piece offset short and sapphire-substrate loads deliver excellent return loss and stability to 9 GHz.

Two OSL holders, a torque wrench, hex key, and calibration data disk complete the kit, designed specifically for Keysight and Agilent network analyzers.
