The Rohde and Schwarz NGPS32 is a dual-channel bipolar voltage source engineered for precision test and measurement applications requiring independent, galvanically isolated positive and negative outputs. Each channel operates in constant voltage or constant current mode, with integrated overvoltage, overcurrent, and overtemperature protection. The instrument delivers fast transient response and low noise performance across demanding R&D, quality assurance, and automated test environments.
