The Keysight N6755A (formerly Agilent) is a 500 W high-performance, autoranging DC power module designed for use with the N6700 Low-Profile Modular Power System and the N6705 DC Power Analyzer. It features low noise, high-speed programming up to 10 to 50 times faster than other programmable power supplies, and optional high-speed test extensions including a digitizer and arbitrary waveform generator.
