Agilent Technologies N1254-61001 Adapter Module

Agilent Technologies N1254-61001 Adapter Module is a GNDU-to-Kelvin adapter in the N1254A family that provides a dedicated Kelvin interface for precise test measurements. The module is designed to connect GNDU signals to a Kelvin path in compatible instrument stacks, a configuration widely described for the N1254A family and used with instruments such as the B1500A Semiconductor Device Analyzer. Official configuration guides reference the GNDU-to-Kelvin adapter variants in this series (for example, N1254A-100) and note that these adapters are furnished for integration with a mainframe in test setups that require accurate GNDU connections. The N1254A family commonly employs a dual-triaxial connector arrangement to facilitate the Kelvin-style interface between the instrument and the device under test. Typical applications include semiconductor device characterization and calibration workflows where GNDU-to-Kelvin connectivity is essential for reliable measurement of device parameters. When paired with appropriate GNDU-to-Kelvin cables and a supported mainframe, this adapter enables a stable GNDU-to-Kelvin connection within a test stack, aligning with the precise, four-terminal sensing philosophy that Kelvin adapters support.
