Cleveland, Ohio Keithley Instruments, Inc. has introduced the Model 2308 portable device battery/charger simulator, a dual-channel battery- and charger-simulating power supply designed to provide low-cost testing of mobile phones with complex transmission schemes and other types of portable devices that consume extremely low amounts of power.
The Model 2308 contains two power supply channels, a DVM for voltage measurements on the DUT and digital control ports for relay control. The total package combines a number of instruments needed in production and saves bench space in the R&D lab.
The Model 2308 is particularly well-suited for design and test of low-power, battery-operated devices such as 3G mobile phones, smart phones, MP3 players, Bluetooth headsets, PDAs, and portable GPS receivers. It is also optimized for components and sub-systems such as baseband/power control chipsets, RF power amplifiers, RF power transistors, transmitters, and transceivers.
The instrument's fast transient output response maximizes production yields by maintaining a stable voltage level under dynamic loading conditions. In addition, its measurement engine enables more accurate characterization of both full power operation and low current sleep modes for quantifying power consumption, said Keithley. The Model 2308 is optimized for ultra-fast test times, allowing manufacturers to lower their cost of test, Keithley said.
Unlike conventional power supplies, the Model 2308 features extremely fast recovery even when load currents change by a factor of 10 or greater, and saves valuable test time by making fast load current measurements. The instrument can change range and make a power line cycle measurement in 27 ms. With four current ranges spanning from 5 A to 5 mA, and resolutions from 100 uA to 0.1 uA, test engineers can monitor small changes in load current measurements for tight quality control on production runs. In addition, load currents, even pulses as narrow as 50 us, are measured with integrating A/D technology, which is said to generate the most stable current readings.
Availability: Three weeks.
