The Rohde & Schwarz NGU411 is a four-quadrant source measure unit (SMU) delivering 20 W of source and sink power in a single-channel instrument. It sources and measures voltage from −20 V to +20 V, with maximum output current of 2 A (≤10 V) and 1 A (>10 V). The unit captures voltage and current data with 6.5-digit display resolution—1 µV voltage resolution and 100 pA current resolution—at acquisition rates up to 500,000 samples/second, enabling real-time characterization of dynamic behavior.
