Agilent/Keysight 6234A DC Power Supply

The Agilent/Keysight 6234A is a dual-output linear DC power supply delivering 75 W total across two independently adjustable, isolated channels. Each output provides continuously variable voltage (0–25 VDC) and current (0–200 mA) with automatic CV/CC limiting and low-noise performance suitable for bench-level circuit development and testing.

Technical Specifications

Each output channel operates across 0–25 VDC and 0–200 mA with independent voltage adjustment. Load regulation measures 0.01% + 1 mV; source regulation is equally tight at 0.01% + 1 mV. Output noise remains minimal at 200 µVrms (PARD RMS) or 1 mV peak-to-peak (PARD pk-pk). The supply draws 35 W input power from a 104–127 VAC, 47–63 Hz mains connection at 0.26 A. Total unit weight is approximately 10 lbs.

Key Features

• Dual independent outputs with isolated voltage and current control


• Constant voltage / constant current limiting protects against overload conditions


• Short-circuit proof design


• Low output noise (200 µVrms PARD RMS, 1 mV peak-to-peak)


• Tight load and source regulation (0.01% + 1 mV)


• Linear topology for stable power delivery to sensitive circuits

Typical Applications The 6234A supports general-purpose electronic testing, component characterization, and circuit development where dual independent supplies and low-noise operation are required. Current-limited outputs prevent damage to prototype circuits during design iteration.

Compatibility & Integration This is a standalone benchtop instrument with standard output terminals. Suitability for specific test setups depends on matching the 0–25 VDC and 0–200 mA per-channel capability to your circuit requirements. The 6234A is discontinued; availability of support documentation may be limited.
