Agilent E3649A — 100 W Dual-Range Dual-Output DC Power Supply
A refurbished Agilent E3649A supplies two independent channels that can each switch between a 35 V / 1.4 A low-voltage range and a 60 V / 0.8 A high-voltage range, delivering 100 W of clean power for mixed-signal prototypes or rack systems. Millivolt-level programming resolution and sub-8 mV peak-to-peak noise keep analogue and RF rails stable, while built-in remote sense removes lead-loss errors. GPIB / RS-232 interfaces and SCPI commands slot straight into automated benches, and on-board memory, tracking mode and full OVP/OCP protection simplify repetitive test setups.
Buying used slashes capital cost and lead-time yet ships ISO-17025-calibrated with Keysight reliability and documentation intact.
