The Keysight 6624A is a 40 W quad-output DC power supply engineered for precision testing and development of noise-sensitive electronics. Four independently programmable outputs deliver flexible voltage and current ranges across a compact 3U package. Dual-range capability on each output pair allows engineers to optimize between voltage and current delivery—outputs 1 and 2 switch between 0–7 V/5 A or 0–20 V/2 A, while outputs 3 and 4 range from 0–20 V/2 A to 0–50 V/0.8 A. Low-noise architecture maintains 500 µV RMS and 3 mV peak-to-peak ripple across the 20 Hz to 20 MHz bandwidth, meeting the stringent requirements of analog circuit characterization and sensitive device testing.
