ROHDE & SCHWARZ NGU401 Source Measure Unit SMU, 1-Channel, 4-Quadrant, 40V, 3A, 60W » NGU401 is a four-quadrant source measure unit. It provides up to 60W of output power and sink power, respectively. The channels are floating, galvanically isolated and protected against overload and short circuits. With six measurement ranges for current and a resolution of up to 6½ digits when measuring voltage, current and power, the R&S®NGU source measure units are perfect for characterizing devices that work from extremely low power consumption to high currents in the ampere range. Using ammeters with feedback-amplifier technology increases accuracy and widens the sensitivity down to the nA range. With an acquisition rate of up to 500000 samples per second, even extremely fast variations in voltage or current can be captured. The instruments provide fast load recovery time of < 30µs combined with minimum overshoot even during a demanding load change. Newark.com
