Rohde & Schwarz NGM-COM2a DC Power Supply

Overview

Rohde & Schwarz NGM202 is a programmable dual-output bench power supply for testing and characterizing electronic circuits and systems. Each of its two channels provides continuously adjustable output from 0–20V with current limiting, delivering up to 6A per channel for a total of 120W. The galvanically isolated, floating output stages protect the device under test while enabling two-quadrant operation—functioning as both source and sink to simulate batteries and dynamic load conditions.
