Agilent/Keysight 6823A DC Power Supply

The Agilent/Keysight 6823A is a dual-function DC power supply and power amplifier designed for precision power delivery in laboratory and R&D environments. It operates in two distinct modes: as a regulated power supply with tight load regulation, or as a linear amplifier with extended frequency response. The instrument combines stable DC output with low-noise amplification, making it suitable for applications requiring both static bias and dynamic signal conditioning.

Rear barrier strip terminals provide direct access to control points, enabling expanded operational flexibility and integration into custom test setups.
