The Agilent/Keysight 66321B is a single-output DC power supply engineered for battery-powered device testing, mobile communication validation, and automated test environments. It delivers 0–15 V at 0–3 A continuous current, with 5 A peak capability (7 ms maximum), up to 50 W output power. The instrument combines precise voltage and current programming with advanced battery emulation, dynamic current measurement, and transient compensation to replicate real-world battery behavior under load.
