The HP/Agilent 66319B is a dual-output DC source purpose-built for mobile communications device testing with integrated battery emulation. It characterizes battery operating life and detects product failures early by simulating real-world battery conditions in cellular phones, PDAs, Bluetooth devices, and wireless LAN equipment. Dual outputs enable simultaneous testing of main battery and charger circuits, optimizing bench space and eliminating the need for multiple supplies.
