The Keysight N7977A is a 2000W, 160V, 12.5A Dynamic DC Power Supply designed for automated test equipment (ATE) applications that require high-speed dynamic sourcing and measurement capabilities. It is part of the Keysight N7900 Series Advanced Power System (APS) family, which is built on the VersaPower architecture. This architecture is engineered to deliver accelerated test throughput and precise measurements, aiming to reduce ATE development time and cost. The N7977A offers significant speed improvements over standard system power supplies, with command processing speeds under 2 ms and fast up/down programming speeds up to 500 µs. It also features an adjustable measurement rate to balance speed and accuracy, enabling detailed characterization of a device under test’s (DUT) power profile.
