The Agilent Technologies E3648A is a 100 W dual-output programmable DC power supply engineered for laboratory testing, circuit development, and automated measurement systems. Each output operates independently with dual-range capability: 0–8 V at 5 A or 0–20 V at 2.5 A per channel. The unit delivers exceptional load and line regulation of 0.01% and combines constant voltage and constant current operation modes, making it suitable for both precision analog circuits and power-hungry device characterization.
Output stability is a defining strength. Voltage ripple and noise measure less than 5 mVpp / 0.5 mVrms across 20 Hz to 20 MHz, while transient recovery occurs in under 50 µsec following load step changes. Programming accuracy for voltage reaches ±(0.05% + 10 mV) in the low-range configuration and ±(0.1% + 25 mV) in the high-range. Current programming accuracy stands at ±(0.2% + 10 mA) and ±(0.15% + 10 mA) respectively.
