The HP/Agilent 6114A is a precision DC voltage source engineered for calibration, standards work, and high-performance laboratory applications. It delivers 0–20 V at 2 A or 20–40 V at 1 A through automatic dual-range operation, eliminating manual switching. Voltage control is achieved via pushbutton settings and fine-adjust knob with 200 µV resolution, while front-panel current control enables constant-current operation with 2 mA resolution.
