The Keysight (Agilent) N6951A Advanced Power System is a 1 kW, single-channel DC power supply engineered for demanding automated test equipment (ATE) applications. Built on Keysight’s VersaPower architecture, it delivers accelerated test throughput—up to 100 times faster than standard system power supplies—with precise voltage and current control across 0 to 20 V DC and 0 to 50 A DC. The instrument combines high-resolution measurement capabilities, programmable waveform generation, and flexible triggering to meet the rigorous demands of R&D, manufacturing, and complex test environments.
