The Keysight M9111A is a PXIe high-speed source/measure unit (SMU) that combines voltage source, current source, ammeter, and voltmeter functions in a single 1-slot module. Engineered for rapid characterization and production testing of RF power amplifiers and front-end modules, it delivers complete voltage changes, stabilization, and current measurements in under 1 ms—dramatically accelerating test throughput compared to traditional benchtop instruments.
