Keithley Instruments: Model 2308 Battery/Charger Simulator

Overview   The Model 2308 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 2308 2308 's rapid response to load changes means there's 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 it's being tested. In contrast, the slow-responding source voltage typical of conventional DC power supply products causes the DUT to perform improperly, leading to production yield problems and costly retesting.   The Model 2308 2308 offers a complete solution for portable device sourcing and load current measurement. It has two independent power supply channels: one is optimized to simulate a battery; the second channel is optimized to perform like a charger for a rechargeable battery. The battery channel’s variable output resistance can be used to simulate the internal resistance of a battery so design and test engineers can simulate a battery’s output for testing devices under realistic operating conditions. This channel also sinks current to simulate a discharged battery. The charger channel can supply a voltage to test a portable device’s battery charge control circuitry, with the battery channel acting as the discharged battery load.   Key Applications: Automated test applications, ATE systems in R&D, design validation, and manufacturing.
