The Keysight (Agilent/HP) 6650 Series comprises 500W high-performance, single-output programmable DC system power supplies. Designed for design verification and automated production testing, these units feature fast, low-noise outputs, built-in measurements, and standard overvoltage/overcurrent protection for DUT safety. The series supports standard GPIB and RS-232 interfaces with SCPI command programming, as well as an advanced serial link feature that allows up to 16 supplies to be controlled through a single GPIB address.
