Agilent / Keysight N3301A Series Modular DC Electronic Loads with 16-bit measurements

The Keysight/Agilent N3301A is a modular DC electronic load mainframe engineered for precision testing and characterization of power sources across diverse applications. This half-rack width mainframe accommodates up to two load modules, delivering configurable power dissipation up to 600 W with stable operation down to zero volts—essential for modern low-voltage power supply verification. The N3301A supports user-installable N330xA series modules, enabling customized test setups that scale with evolving requirements. Built-in 16-bit measurement capabilities provide simultaneous output monitoring, while programmable control via GPIB (IEEE-488), RS-232, analog ports, and list programming accommodates both automated and manual testing workflows.
