Agilent/Keysight 6216B DC Power Supply

The Agilent/Keysight 6216B is a benchtop DC power supply delivering 0–25 V at 0–400 mA with 10 W output power. It operates in constant voltage and constant current modes with automatic crossover when preset limits are exceeded. Front-panel coarse and fine voltage controls and a switchable meter enable precise voltage or current monitoring. Binding post output terminals suit standard lab configurations.

– Technical Specifications

Output Power and Range
• Output voltage: 0–25 V DC
• Output current: 0–400 mA
• Output power: 10 W

Regulation Performance
Load regulation in constant voltage mode is better than 0.01% + 4 mV across full to no-load current changes. Constant current mode achieves less than 0.03% + 250 µA for zero to maximum output voltage swings. Line regulation holds less than 0.01% + 4 mV in constant voltage and 0.01% + 250 µA in constant current for input variations within rated range.

Output Quality
Ripple and noise in constant voltage mode measures less than 200 µV rms or 1 mV peak-to-peak (DC to 20 MHz). Constant current mode exhibits less than 500 µA peak-to-peak noise. Stability after 30-minute warm-up is better than 0.10% + 5 mV (CV) or 0.10% + 5 mA (CC) drift over 8 hours.

Temperature and Impedance
Temperature coefficient is less than 0.02% + 1 mV per °C in constant voltage mode. Internal impedance as a constant voltage source is less than 0.02 Ω (DC to 1 kHz), less than 0.5 Ω (1 kHz to 100 kHz), and less than 3.0 Ω (100 kHz to 1 MHz). Transient recovery to within 10 mV follows a full load current step in under 50 µs.
