2308 Portable Device Battery/Charger Simulator
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) transi-
tions nearly instantaneously from a sleep or
standby mode to the full power transmit state,
the Model 2308's rapid response to load changes
means there's little transient voltage drop from
the programmed output voltage and the output
Fast transient response power supply
Fast transient response power supply
recovers quickly . This fast response is particu-
larly 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 power supplies
causes the DUT to perform improperly, lead-
ing to production yield problems and costly
retesting .
The Model 2308 offers a complete solution for portable device sourcing and load current measure-
