The Agilent/Keysight 6051A is a mainframe DC electronic load system designed to house modular load cards for power source evaluation and component testing. It supports up to 600 watts of total maximum power and accommodates two 60501B, 60502B, or 60503B modules, or one 60504B or 60507B module. The instrument delivers precise control across constant current, constant voltage, and constant resistance operating modes with integrated GPIB command interface for both manual benchtop operation and automated test integration.
