TSP #211 - Rohde & Schwarz NGU401 500kS/s Source Measure Unit Review, Teardown & Experiments

In this episode Shahriar reviews the latest edition to the R&S SMU family, the NGU401. https://www.rohde-schwarz.com/us/prod... This instrument offer four-quadrant operation, 60W total output power, 6.5 digit resolution as well as 500kS/s digitizers on both voltage and current readbacks. The instrument also offers a verity of output control and arbitrary waveform generation.
