Agilent/Keysight 85057A

The Agilent/Keysight 85057A is a 2.4 mm verification kit that validates network analyzer calibration and RF measurement accuracy across extended frequency ranges. This 50 Ohm standard provides NIST-traceable measurement data to confirm system performance and maintain metrological integrity in production and service environments.

– Technical Specifications

Connector Type: 2.4 mm

Impedance: 50 Ohm

Frequency Range: 45 MHz to 50 GHz

– Key Features

The 85057A delivers factory-measured verification data with full traceability to NIST standards. Each kit includes measurement uncertainty documentation supplied on disk or printed form. The standard set comprises four precision elements: 50 Ohm airline, stepped impedance airline, 20 dB attenuator, and 40 dB attenuator. These components enable rapid verification of calibration drift, system repeatability, and connector repeatability across the full operating band.

– Typical Applications

This verification kit serves to confirm network analyzer measurement calibration before critical device characterization. It validates the integrity of calibration kits—particularly the 85056A and 85056D—and detects performance degradation in production test systems. The kit is also used to verify measurement uncertainty budgets and document system traceability during compliance audits.

– Compatibility & Integration

The 85057A integrates with Keysight PNA series network analyzers and legacy Agilent instruments including the 8510, 8719, 8720, and 8722 series. It works in conjunction with Keysight 2.4 mm calibration kits to complete the full calibration and verification workflow. The kit requires compatible 2.4 mm connectors on network analyzer test ports.
