Agilent/Keysight 16442B

The Keysight 16442B is a modular test fixture that interfaces semiconductor parameter analyzers and device analyzers with packaged electronic components for precise DC characterization. The fixture accommodates a broad range of component types through interchangeable socket modules, supporting both laboratory and production measurement environments. Its design includes a safety interlock system that prevents electrical hazards when operating with high-voltage instruments, blocking voltage output when the fixture lid is open.
