The Keithley 2306 is a dual-channel precision battery/charger simulator designed specifically for testing portable, battery-operated devices such as cellular phones, IoT hardware, and RFIC power amplifiers. Featuring ultra-fast transient voltage response, variable output resistance (on Channel 1), and high-resolution pulse current measurements, the 2306 simulates a real battery's behavior under dynamic pulsed-load conditions while also providing an auxiliary charger simulator or power supply on its second channel.
