HP / Agilent 16095A Probe Test Fixture

The HP/Agilent 16095A Probe Test Fixture enables precise 4-terminal pair impedance measurements on discrete components and surface mount devices. This specialized accessory delivers accurate, repeatable connections across laboratory and production environments. Multiple connection methods—standard probe, alligator clip adapter, and BNC adapter—accommodate diverse DUT geometries and mounting configurations. Operating to 110 MHz, the fixture integrates with leading impedance analyzers to minimize lead and contact impedance errors while supporting DC bias levels to ±40 V.

– Compatibility & Integration

Primarily designed for the HP/Agilent 4192A LF Impedance Analyzer. Compatible with other 4-terminal pair LCR meters and impedance analyzers, including the 4285A. When using with analyzers other than the 4192A, ensure the probe ground lead is not connected to the instrument’s ground terminal. Verify compatibility with your specific impedance analyzer before deployment. Electrical length compensation should be entered into the instrument when supported for improved measurement accuracy.
