Agilent/Keysight E4356A

The Agilent/Keysight E4356A is a dual-range DC power supply engineered for telecommunications testing, delivering clean, low-noise power for sensitive equipment validation. It combines 2100 W maximum output with integrated voltage and current measurement, eliminating the need for external instrumentation. The unit sources and sinks current, accelerating test cycles on capacitive loads while protecting devices through active voltage clamping and current limiting. Standard SCPI programming and VXIplug&play drivers streamline system integration across multi-supply configurations.
