Agilent / Keysight 85051B Verification Kit, 7 mm

The Keysight 85051B Verification Kit is a precision standard set designed to verify the calibration performance and measurement accuracy of 7 mm network analyzers. This kit contains mechanical and electrical standards with known characteristics traceable to the U.S. National Institute of Standards and Technology (NIST), enabling independent validation of analyzer performance across the full operating bandwidth.

Technical Specifications

Connector Type: 7 mm Frequency Range: 300 kHz to 18 GHz Traceability: NIST-traceable measurement data and uncertainties

Key Features The kit comprises ten precision standards selected to thoroughly characterize network analyzer performance. Components include 10 cm and 50 Ω airlines, stepped impedance airline, 20 dB and 50 dB attenuators, 25 Ω mismatch airline, and open-end wrench. Mechanical characteristics are verified through specialized gaging processes; electrical characteristics are confirmed through rigorous testing. All factory-measured verification data is provided on USB drive and individual datasheets, with anti-virus scan report included. Each standard exhibits known electrical behavior traceable to Keysight reference standards and NIST. The kit arrives in a foam-lined storage box with protective caps and comprehensive user and service documentation.

Typical Applications Use this kit to independently verify network analyzer calibration integrity and measurement system performance. Validation can be performed at any point during analyzer operation, serving as a confidence check on calibration accuracy without requiring analyzer recalibration. The kit functions as a transfer standard for measurement traceability chains.

Compatibility & Integration Designed for use with Keysight 7 mm calibration kits (85050B/C/D series). Compatible with Keysight PNA series network analyzers and legacy Agilent 8510, 8719, 8720, and 8722 series instruments. Installation requires selection of the appropriate calibration kit definition within analyzer memory or external media prior to use. Recertification of the verification kit itself requires return to Keysight Technologies, as specialized measurement equipment is not commercially available.
