Keithley 2304A

The Keithley 2304A is a 100 W precision power supply engineered for automated testing of battery-powered devices. It sources 0-20 V DC at 0-5 A while simultaneously sinking up to 3 A, making it ideal for simulating battery behavior and characterizing power consumption during dynamic load transients. Fast transient response - recovery within 100 mV in 40 µs or less - combined with 100 nA DC current measurement sensitivity and 0.2% basic accuracy enables comprehensive analysis of wireless communication devices and portable electronics experiencing rapid current fluctuations. The instrument measures current pulses from 60 µs to 833 ms duration, capturing peak, average, and baseline values with 33.3 µs resolution. Load regulation of 0.01% + 2 mV and line regulation of 0.5 mV ensure stable voltage delivery across test scenarios.
