Agilent/Keysight AC6906L

The Keysight AC6906L is a 6 kVA three-phase AC power source that combines AC/DC output capability with integrated measurement and analysis functions. It is a power source, multimeter, harmonic analyzer, and power analyzer in a single compact instrument. The AC6906L generates variable-frequency AC power up to 320 Vrms (or 452 V DC), with maximum output current of 60 A across single-phase, three-phase four-wire, and mixed AC+DC configurations.

Built-in harmonic analysis extends to the 50th harmonic for both voltage and current, enabling detailed characterization of power quality and equipment response across diverse operating conditions.
