Agilent/Keysight 85055A

The Agilent/Keysight 85055A is a precision Type-N, 50-ohm verification kit engineered to calibrate and verify network analyzer performance across the RF and microwave spectrum. It delivers factory-measured calibration standards with NIST-traceable measurement data, enabling repeatable and accurate characterization of high-frequency test equipment from 300 kHz to 18 GHz.

– Technical Specifications

• Connector Type: Type-N with precision slotless connectors (PSC)
• Impedance: 50 ohms
• Frequency Range: 300 kHz to 18 GHz
• Type-N Pin Depth Offset: Approximately 5.26 mm (0.207 inch)

– Key Features

The kit includes four calibration standards: 20 dB attenuator, 50 dB attenuator, 25 ohm mismatch airline, and 50 ohm airline (10 cm length). Precision slotless connectors eliminate calibration traceability loss from male pin diameter variation and deliver enhanced measurement repeatability through non-changing connector characteristics.

Factory verification data arrives with the kit for direct use in network analyzer verification processes. All measurement uncertainties are traceable to NIST standards. Environmental qualification follows Keysight Environmental Test Manual methodology with type testing aligned to IEC 60068-2 and MIL-PRF-28800F Class 3, covering temperature, humidity, shock, vibration, and altitude stresses.

Operating temperature stability is critical before measurement due to component dimensions; instruments must reach thermal equilibrium prior to use.

– Typical Applications

• Network analyzer calibration and performance verification
• RF and microwave measurement system validation
• High-frequency test equipment characterization
• Traceable standard deployment in metrology labs

– Compatibility & Integration

The 85055A integrates with Keysight PNA Series analyzers, Agilent 8510, 8719, and 8720 network analyzers, Agilent spectrum analyzers, and Agilent scalar network analyzers.
