Agilent / Keysight 85031B Calibration Kit, DC to 6 GHz, 7 mm

The Keysight 85031B is a DC to 6 GHz calibration kit engineered for precise one-port and two-port calibration of network analyzers and RF test equipment using 7 mm connectors. This metrology-grade kit delivers the fixed standards necessary for reliable coaxial measurements and includes broadband load terminations and a combination open/short circuit standard, all optimized for repeatable performance across its operating frequency range.

Technical Specifications

• Frequency Range: DC to 6 GHz


• Connector Type: 7 mm


• Characteristic Impedance: 50 Ω


• Return Loss: ≥52 dB (DC to 5 GHz); ≥46 dB (5 to 6 GHz)

Kit Components

• Two 50 Ω broadband load terminations with distributed resistive element on sapphire substrate


• One combination open/short circuit standard with precision-machined construction

Key Features The broadband loads feature a rugged internal structure designed for repeatable connections and stable return loss performance to 6 GHz. The combination open/short standard uses precision-machined parts that control pin depth to minimize phase errors during calibration. The 7 mm connector interface is a precision standard where mechanical characteristics - including center conductor protrusion and pin depth - are verified by Keysight to ensure electrical performance.

Typical Applications Calibration of Keysight and Agilent network analyzers for measurement of devices with 7 mm connectors. Suitable for one-port and two-port calibration procedures in coaxial measurement systems.
