Battery Testing

The 2302 is a fast transient response battery simulating Power Supply with built-in digital voltmeter. This precision DC power supply product has ultrafast transient response so they can have output characteristics identical to actual batteries. This supply employs an unique variable output resistance so the voltage output can emulate a batterys response. It 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. Ultrafast response to transient load currents Optimized for development and testing of battery-powered devices Variable output resistance for simulating battery response (US patent no. 6,204,647) Pulse peak, average and baseline current measurements 100nA DC current sensitivity Current step measure function Sink up to 3A Open sense lead detection Built-in digital voltmeter

The dual channel Battery/Charger Simulator was designed specifically for development and test applications of portable, battery-operated products, such as cellular and cordless telephones, mobile radios, and pagers. This precision DC power supply product 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 batterys response. It 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, they can monitor DUT power consumption by measuring both DC currents and pulse load currents. The battery-simulator channel can be programmed to operate like a discharged rechargeable battery, sinking current from a separate charger.

The Model 2308 Portable Device Battery/Charger Simulator is optimized for use in testing mobile phones and other portable, battery-operated devices. When a device-under-test (DUT) transitions nearly instantaneously from a sleep or standby mode to the full power transmit state, the Model 2308s rapid response to load changes means theres little transient voltage drop from the programmed output voltage and the output recovers quickly. This fast response is particularly critical when testing portable devices with a pulsed mode of operation because it allows the device to perform properly while its being tested. In contrast, the slow-responding source voltage typical of conventional power supplies causes the DUT to perform improperly, leading to production yield problems and costly retesting.
