Agilent / Keysight 85053B Verification Kit, 3.5 mm 300 kHz to 26.5 GHz.

The Keysight 85053B Verification Kit is a calibration standard set designed to verify network analyzer performance and accuracy across 300 kHz to 26.5 GHz. Equipped with 3.5 mm connectors, this kit delivers NIST-traceable measurement data and uncertainties, ensuring instruments operate within specified parameters. It is the verification companion to Keysight PNA series analyzers and works alongside the 85033E and 85052B calibration kits.

Technical Specifications

• Frequency Range: 300 kHz to 26.5 GHz


• Connector Type: 3.5 mm (mode-free operation to 34 GHz; mates with standard SMA connectors)


• Impedance: 50 Ohms nominal


• Return Loss: Greater than 46 dB (3.5 mm beadless airline)


• Traceability: NIST

Key Features

• 7.5 cm airline (50 Ohm)


• Stepped impedance airline (25 Ohm nominal, coefficient = 0.60)


• 20 dB attenuator


• 40 dB attenuator


• Factory-measured verification data on USB drive and data sheets


• Anti-virus scan report included


• Storage box and user/service guide The precision 3.5 mm beadless airline delivers exceptional return loss performance. All calibration standards include factory-measured data formatted for direct PNA system verification workflows. Electronic verification data and accompanying documentation must be backed up immediately upon receipt; Keysight maintains these files for one year only.

Typical Applications

• Network analyzer performance verification post-calibration


• Keysight PNA series instrument validation


• S-parameter measurement confidence assessment


• Periodic calibration kit verification

Compatibility & Integration Designed for Keysight PNA series network analyzers. Integrates with 85033E and 85052B 3.5 mm calibration kits. The 3.5 mm connector requires careful handling to prevent damage, particularly when mated with lower-grade SMA connectors.
