The HP/Agilent 6629A is a 50 W precision DC power supply delivering four fully isolated, programmable outputs in a compact 3U rackmount package. Each output operates in dual ranges: 0–16 V / 0–200 mA (low range) or 0–50 V / 0–1 A (high range), with selectable 0–16 V / 0–2 A configuration. Programming accuracy reaches 0.016% + 3 mV (voltage, low range) and 0.04% + 185 µA (current, low range). Ripple and noise specifications are 500 µV RMS and 3 mV peak-to-peak across the 20 Hz to 20 MHz bandwidth, with 0.1 mA RMS current ripple. The instrument features remote sensing to 10 V drop per load lead, active current sinking capability at rated output current, and very fast CV/CC crossover protection. Output programming response time is 6 ms.
