Keithley 2308 Portable Device Battery/Charger Simulator

The Keithley 2308 Portable Device Battery/Charger Simulator is meticulously engineered for the testing and evaluation of mobile phones and various other portable, battery-powered devices. A standout feature of this simulator is its remarkable speed, allowing for rapid transitions from sleep or standby modes to full power transmit states. With the Keithley 2308, minimal transient voltage drop occurs from the programmed output voltage due to its swift response to load changes, ensuring that the output recovers quickly. This critical capability is vital for effectively testing portable devices that operate in pulsed modes, enabling them to perform accurately throughout the testing process. In stark contrast, conventional power supplies tend to have slower response times, leading to improper device performance and potential production yield issues, resulting in costly re-evaluations.
