The Keysight (Agilent) 6655A is a 480W, single-output DC power supply offering 0–120V and up to 4A, designed for fast, low-noise output in automated test systems. With analog control of voltage and current, it achieves programming accuracy of ±0.06% + 51 mV (voltage) and ±0.15% + 4 mA (current). Ripple is limited to 700 µV RMS and 2 mA RMS. Fan-speed control ensures quieter operation, while fast up/down programming reduces test cycle time for higher throughput.
Ideal for system integration and test automation, the 6655A combines precision, speed, and quiet operation in high-voltage testing environments.
