Key Features

• Offset Opens and Shorts. Precision-machined reflection standards with tight tolerances minimize phase error and ensure repeatable connector mating across the frequency band.


• Metrology-Grade Terminations. 50 Ω loads optimized to 50 GHz using distributed resistive elements on sapphire substrate. High internal repeatability and stable return loss performance.


• 2.4 mm Adapters. Precision adapters with matched electrical lengths for gender conversion and non-insertable device calibration. Built to tight tolerances for broadband stability and repeatable connections.


• Torque Control. Included torque wrenches (5/16 in, 90 N-cm / 8 in-lb) and open-end wrench ensure consistent standard connections and proper mechanical engagement.


• NIST Traceability. Calibration measurements traceable to United States National Institute of Standards and Technology standards.

Typical Applications Two-port calibration of network analyzers for DC to 50 GHz component characterization. Calibration of test ports equipped with 2.4 mm connectors for S-parameter measurements in microwave and millimeter-wave systems.

Compatibility & Integration Designed for Keysight (formerly Agilent/HP) network analyzers operating up to 50 GHz. Calibration kit definition files (.xkt) are available and typically pre-loaded in Keysight VNA firmware for plug-and-play operation.
