Keysight (Agilent) 16143B Mating Cable for HP 4338A/B

The Keysight (Agilent) 16143B is a mating cable assembly designed to interface test leads with HP 4338A and 4338B Milliohmmeters. This accessory enables connection of various Kelvin clip, IC clip, probe, and alligator clip leads to precision resistance measurement instruments, maintaining signal integrity across low-ohm measurements. The cable features a 4-Terminal BNC connector and measures approximately 0.6 m in length.

The 16143B was discontinued effective May 1, 2006, with end-of-support life on May 1, 2011.

Technical Specifications

• Connector Type: 4-Terminal BNC


• Cable Length: 0.6 m


• Supported Test Lead Types: Kelvin Clip Leads (16005B), Kelvin IC Clip Leads (16005C/D), Pin-Type Probe Lead (16006A), Alligator Clip Leads (16007A/B)


• Lead Configuration: Accommodates any combination of two test lead types

Key Features

• Dual lead-type compatibility allows flexible test configurations without multiple cables


• 4-Terminal BNC connector ensures reliable impedance matching for low-resistance applications


• Compact 0.6 m length suitable for benchtop and field measurement setups

Typical Applications

• Low-ohm resistance measurements with Kelvin clip leads on PCB test points


• Contact resistance verification using IC clip leads on integrated circuits


• Production test environments requiring rapid lead reconfiguration


• Maintenance and troubleshooting of electrical contacts and interconnects

Compatibility & Integration The 16143B pairs directly with HP 4338A and HP 4338B Milliohmmeters. It accepts all standard Keysight test lead accessories in the 16005/16006/16007 series, enabling custom measurement setups for resistance ranges typically spanning the milliohm scale. Original equipment context indicates this cable was engineered specifically for the milliohmmeter architecture of the 4338 series.
