The Keysight E36313A is a high-performance, 160 W triple-output programmable DC power supply designed for benchtop and automated test applications. Featuring low output ripple and noise, excellent programming and readback accuracy, and standard USB/LAN interfaces (with optional GPIB), it provides highly reliable clean power. The instrument is equipped with advanced features such as low-range current measurement, data logging, output sequencing, auto-series/parallel configurations, and remote sensing to satisfy rigorous device-under-test (DUT) characterization requirements.
