The single-channel Keithley 2302 Fast Transient Response battery simulator and dual-channel Model 2306 battery/charger simulator were designed specifically for development and test applications of portable, battery-operated products, such as cellular and cordless telephones, mobile radios, and pagers. Keithley 2302 is a precision power supply that has ultra-fast transient response so they can have output characteristics identical to actual batteries.

These supplies employ a unique variable output resistance so the voltage output can emulate a battery's response (U.S. Patent No. 6,204,647). They provide 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, they can monitor DUT power consumption by measuring both DC currents and pulse load currents. The Keithley 2302's battery-simulator channel can be programmed to operate like a discharged rechargeable battery, sinking current from a separate charger or from the Model 2306's charger-simulator channel.

The battery-output channels in the Keithely 2302 are designed to simulate the output response of a battery.
This capability, combined with their fast transient response, makes it possible to power the device during test in exactly the same way as a battery will power the device during actual use.
