Agilent/Keysight 6265B DC Power Supply

The Agilent/Keysight 6265B is a DC power supply delivering 0–40 V and 0–3 A output across 0–55 °C operation. It operates in both constant voltage and constant current modes, providing load regulation of 0.01% + 200 µV (CV) and 0.02% + 2 mA (CC), with line regulation matching those specifications. Output ripple and noise measure 1 mV rms / 5 mV peak-to-peak in CV mode and 25 mA rms in CC mode, spanning 20 Hz to 20 MHz.
