The Keysight (Agilent) 6644A is a 200 W programmable DC power supply delivering 0–60 V at 0–3.5 A (at 40°C) for automated test systems, design verification, and production line integration. Built-in GPIB interface with SCPI command support enables remote voltage and current control, real-time measurement feedback, and serial linking of up to 16 units to a single GPIB address for multi-supply test configurations.
