The Keysight N7972A Advanced Power System is a 2000 W dynamic DC power supply engineered for automated test equipment (ATE) platforms requiring high-speed dynamic sourcing and precision measurement. Operating at 40 V and 50 A maximum output, this single-output unit delivers command processing under 2 ms and fast programming speeds to 500 µs, enabling rapid device characterization without sacrificing measurement accuracy. Built on Keysight’s VersaPower architecture, the N7972A combines 18-bit measurement resolution with two-quadrant operation capability, arbitrary waveform generation, and programmable slew rates—making it ideal for power storage testing, transient response analysis, and dynamic load profiling.
