The Keysight (Agilent) 41501A is an SMU and Pulse Generator Expander designed to extend the capabilities of the 4155A/B and 4156A/B Semiconductor Parameter Analyzers. It is not a standalone system, but rather a mainframe expansion unit that can house high-current SMUs, medium-power SMUs, and Pulse Generator Units (PGUs) to handle more complex semiconductor device characterization tasks.
