The Agilent/Keysight N3304A is a 300 W electronic load module engineered for insertion into N3300A or N3301A mainframes. It delivers precise DC load simulation across constant current, constant voltage, and constant resistance operating modes, enabling comprehensive characterization of power supplies, batteries, and regulated DC sources. The module performs simultaneous voltage and current measurements with waveform digitization to 4096 data points, capturing ripple and noise content from 20 Hz to 10 MHz for detailed power source analysis.
