N3301A

Keysight Technologies (Agilent HP)Electronic Loads

The Keysight N3301A (formerly Agilent N3301A) is a compact, 2-slot programmable DC electronic load mainframe designed for high-density, high-speed test systems. Operating with up to two single-slot modules or one double-slot module, it provides a flexible and modular load solution with built-in GPIB and RS-232 control, making it ideal for high-volume automated testing of power supplies and power components.
