Keysight 85065A Dielectric Probe Kit 200 MHz to 50 GHz with 7mm APC-7 Connector for VNA Material Characterization Pre-Owned Fully Tested

The Keysight 85065A Dielectric Probe Kit is a precision measurement accessory designed for material characterization using Keysight vector network analyzers (VNA). Covering a broad frequency range from 200 MHz to 50 GHz, this probe kit enables accurate measurement of dielectric properties including permittivity (εr') and loss factor (εr''). The 7mm (APC-7) precision connector ensures reliable, repeatable RF connections for high-accuracy measurements.

• Food and agricultural product moisture/quality analysis
• Material science R&D for new dielectric materials and coatings
• Radio frequency (RF) absorber and shielding material evaluation

The 85065A coaxial probe method is a non-destructive, broadband technique for measuring dielectric properties. The probe tip is placed in direct contact with the material under test. The VNA measures the reflection coefficient (S11), and the companion 85071E software computes the complex permittivity. Calibration is performed using open, short, and reference liquid (deionized water) standards before measurement.
