The Keysight N1297B is a banana-to-triaxial adapter that enables 4-wire (Kelvin) measurements for precision low-current applications. It accommodates measurements below 1 nA by leveraging high-performance triaxial cable characteristics, eliminating the parasitic effects inherent in standard 2-wire connections. The adapter bridges banana connectors to triaxial outputs, supporting direct integration with triaxial test fixtures and wafer probers used in semiconductor characterization and low-level signal measurement.
