Rohde & Schwarz NGU Series SMUs

The Rohde & Schwarz NGU Series Source Measure Units are precision instruments designed for testing and development applications that require both sourcing and sinking of power. Key features include two or four quadrant operation, high-speed data acquisition, and a wide range of voltage and current outputs up to 60W. These units are known for minimal residual ripple, low noise, and high-resolution touch screen interfaces. The NGU Series are particularly effective in semiconductor testing and other industries requiring precise power control and analysis.
