Agilent/Keysight 6824A DC Power Supply

The Agilent/Keysight 6824A is a dual-function DC power supply and power amplifier engineered for precision testing, product development, and R&D applications requiring stable, programmable output. The instrument operates as a bipolar ±50 V source with sink/source capability and functions as a variable-gain amplifier with 100 V peak-peak output, all integrated into a compact 7.7 kg package.
