The Keysight N7973A Advanced Power System is a 2000 W dynamic DC power supply engineered for automated test equipment applications requiring high-speed dynamic sourcing and precision measurement. Built on the VersaPower architecture, this single-output 60 V, 33 A system delivers test speeds up to 100 times faster than standard power supplies, with command processing in less than 2 ms and programming speeds reaching 500 µs. The N7973A performs voltage and current measurements with 18-bit precision and DMM-like accuracy, while advanced measurement functions include power, peak power, watt-hour, and amp-hour calculations. Two-quadrant operation enables smooth transitions between positive and negative currents—full capability requires the optional N7909A power dissipater, though standalone units support 10% rated current two-quadrant operation. Arbitrary waveform generation and list programming facilitate complex power simulations and sequential test sequencing. The 2U rack-mount chassis connects via LAN (LXI Core), USB, and GPIB, accepting 240 VAC, 1-phase input. Multiple units can be paralleled to reach 10 kW with equal current sharing. Optional N7908A black-box recorder tracks power events, measurement data, triggers, and status bits during operation.
