The Keysight 6622A is an 80 W dual-output DC power supply engineered for automated test systems and benchtop applications. Each of its two isolated outputs operates across dual voltage and current ranges, delivering precise control with low noise and excellent regulation. GPIB programmability enables full remote automation of all power supply functions except GPIB address assignment, making integration into complex test environments straightforward. The unit excels at fast voltage and current programming, supported by an active down-programmer capable of sinking full rated current for rapid voltage reduction without load dependency.
