The single-channel 2302 Battery Simulator was designed specifically for development and test applications of portable, battery-operated products, such as cellular phones, wireless devices and wearables. This precision power supply has ultrafast transient response so it can have output characteristics identical to actual batteries. This supply employs a unique variable output resistance so the voltage output can emulate a battery’s response (U.S. Patent No. 6,204,647).

This power supply provides stable voltage outputs, even when a device-under-test (DUT) makes the rapid transition from the standby (low current) state to the RF transmission (high current) state. In addition, it can monitor DUT power consumption by measuring both DC currents and pulse load currents. The 2302’s battery-simulator channel can be programmed to operate like a discharged rechargeable battery, sinking current from a separate charger.
