Rohde and Schwarz NGU401 Four-quadrant source measure unit, 60 W

The Rohde & Schwarz NGU401 is a single-channel, four-quadrant Source Measure Unit (SMU) rated for 60 W total power output. It delivers precise voltage and current sourcing and sinking capabilities across both quadrants, enabling accurate characterization of semiconductors, power management circuits, and discrete components. The four-quadrant topology supports bidirectional power flow—sourcing current in both voltage polarities and sinking current in both directions—making it essential for battery simulation, device I-V curve tracing, and dynamic load testing in laboratory and production environments.
