The Keysight N1254A GNDU to Kelvin Adapter Module converts Ground Unit connections to four-wire Kelvin configurations, eliminating measurement errors from lead resistance and thermal electromotive forces. This precision adapter enables accurate low-resistance and low-level signal measurements in semiconductor testing and parametric characterization. Compact construction and triaxial-to-BNC connector configurations integrate directly with Keysight’s parameter analyzers and switching mainframes.
