The Keysight 6253A is a dual-output DC power supply delivering independent, simultaneously adjustable voltage and current from two identical sections. Each output section provides 0–20 VDC at 0–3 ADC with 120 W maximum power per section, suitable for benchtop and rack operation. The instrument supports constant voltage/constant current (CV/CC) modes and offers auto-series, auto-parallel, and auto-tracking capabilities for flexible power configurations. Floating outputs enable use as positive and negative sources, and auto-tracking capability permits opposite-polarity voltages up to ±20 V. Front and rear output terminals provide convenient access, while remote sensing and remote programming via rear panel external voltage or resistance control enhance system integration. Ripple and noise performance reaches 200 µV rms in CV mode (20 Hz–20 MHz) with load regulation of 0.01% + 4 mV for voltage and 0.01% + 250 µA for current.
