Agilent/Keysight 6825A Power Supply/Amplifier

The Agilent/Keysight 6825A is a dual-range power supply/amplifier combining precision voltage sourcing with current sink capability for ATE and benchtop test applications. It delivers stable DC outputs across two selectable ranges with exceptional load and line regulation, supported by low noise performance and rapid transient recovery. The instrument integrates sourcing and sinking functions in a compact form factor, making it suitable for component characterization, circuit validation, and systems-level testing where programmable control and signal integrity are critical.
