A Greater Measure of Confidence www.keithley.com 1.888.KEITHLEY (U.S. only) The Model 2303/2304A P ower Supplies provide both voltage control and power consumption moni to ring for automated testing of portable, battery-operated devices . These power supplies are optimized for testing battery-operated, wire - less communication devices such as cellular phones that undergo substantial load changes for very short time intervals These power sup- plies exhibit outstanding voltage stability during pulse load changes and can simultaneously measure load currents, even if they are short pulses In addition, this family of power supplies can sink current and, thus, take on the charac - teristics of a discharged, rechargeable battery for testing chargers and charger-control circuitry 5a ou tput Capacity Both the 100W M odel 2304A and the 45W M odel 2303 can supply 5A at 20V for the Model 2304A a nd 9V f or the Model 2303) to serve the peak pulse loading requirements of battery-oper- ated devices . In both instruments, the maximum current of 5A c an be delivered continuously . The Model 2304A can supply up to 20V DC while the Model 2303 can supply up to 15V fa st r esponse to lo ad Changes Keithley’s High Speed Power Supplies are designed to simu l ate the current drive capacity of a battery . The power supplies simulate a bat- tery’s re s ponse d uring a large load change by minimizing the maximum drop in voltage and recover - ing to within 100mV of the original voltage in 40µs or less . W hen a portable device such as a cellular phone switches from standby mode to the full power mode of operation, the current draw on the power supply can change by as much as 1000% . While a bat- tery’s voltage will de c rease by the value of the voltage drop across the battery’s low internal resist - ance, a con v en t ion a l power supply will have a significant voltage drop (more than one volt) and take milli s econds to recover to the original voltage level . For portable devices that operate at full power only for short intervals, the full power event is over before a conventional power supply can recover . F or example, cellular phones designed in ac c or d ance with the GSM cellular phone standard transmit and receive information in 576µs pulses . If the power supply used to test them cannot re c ov e r quickly enough, the per f or m ance of the device- under-test will be c ompro m ised by the power supply . If the power supply voltage drops below the threshold of the phone’s low- b attery detec- tion circuitry for a sufficient amount of time, the phone will turn off during testing, giving a false indication of a failed device T he Models 2303/2304A’s fast transient response to large load changes will enable test engineers to test their portable products properly and eliminate false failures due to conventional power supplies with slow re s ponse times . In this way, the power supplies ensure maximum production throughput when testing portable devices

www.keithley.com 1.888.KEITHLEY (U.S. only) A Greater Measure of Confidence The Models 2303/2304a perform a continu- ous integration to make peak, average, and baseline measurements on complex load current waveforms. Integra t ion times can be programmed with 33.3µs resolution. Trigger Level 33.3µs is the narrowest (shortest) time interval High Low Average Low High Average I= i dt i t fas t Measurements for Power C onsumption an alysis As manufacturers of portable devices strive to extend battery life and the length of time between recharges, power consumption has become an im p or t ant performance indicator . T herefore, in production testing, accurate peak power and average power measurements are criti- cal . These mea s ure men ts are complicated by the fact that wireless tele c om m unication devices draw full load current in short pulses . The Mo d els 2303/2304A’s pulse readback mea s ure men t mode makes it possible to capture peak and average values on pulses as short as 60µs This allows the power supply to power a device-under-test and determine its current con s ump t ion to qualify the device for its specified power consumption . In addition to making measurements on short pulses, the 2303/2304A power supplies can measure a current pulse peak or a current pulse train that is as long as 833ms For random pulse trains that have periods longer than 833ms, the power supplies have a s pecial long integration mode that can make an average current meas - urement on up to 60s of data . To capture low current pulses from very low power devices, the Model 2303-PJ provides pulse measurement on both the 5A and 500mA r anges . ac curate l ow Current Measurements The Models 2303/2304A are well-suited for m aking fast, accurate measurements of sleep and standby mode currents because they are based on Keithley’s ex p er t ise in low current measurement tech n ol o g ies . With 100nA resolution, the power supplies offer the precision needed to monitor the low sleep mode currents in today’s products and in future products They can also measure these low currents with 0 .2 % basic accuracy . High Current sinking Capacity K eithley’s power supplies can act as an electron- ic load and sink as much as 3A (Model 2304A) and 2A Model 2303), so they can simu l ate a discharged rechargeable battery . Therefore, they can be used to verify the performance of a portable device’s charger The power supplies’ cur r ent dissipation capacity allows them to test even high-current fast chargers . I ndependent Digital Voltmeter Inputs While many programmable power supplies offer output readback ca p a b ilities, Keithley’s power supplies are the only instruments available that also of f er a set of DVM inputs . These inputs allow the Model 2304A to measure signals from 0 to +20V (0 to +15V for the Model 2303) anywhere in the test system with the same rated accuracy as the voltage readback The DVM and the power source can operate simul t aneously . For many applications, the power supplies’ built-in DVM elimi n at e s the expense and space that a separate voltage measurement in s tru men t would require . rem ote Display op tion If the Model 2303 or 2304A must be mounted in a location in which the display is not readily visible, an optional Model 2304-DISP Display Module can be mounted at a more convenient point, then plugged into the power supply unit T he display module also includes all in s tru men t controls, so that the power supply can be oper- ated remotely from the more ac ce s s ible location . or dering Information 2304a H igh sp eed Precision re adback Power su pply (100W) 2303 H igh sp eed Precision re adback Power su pply (45W) 2303-PJ H igh sp eed Precision re adback Power su pply (45W, 500ma range replaces 5ma range) a ccessories s upplied us er and service manuals, Cs- 846 output connectors mating terminal aC CE ssorI E s aVaIl ablE 2304-DISP R emote Display CS-846 M ating Output Connector CablEs 7007-1 S hielded IEEE-488 Cable, 1m (3 .3 f t) 7007-2 S hielded IEEE-488 Cable, 2m (6 .6 f SC-182 L ow-Inductance Coaxial Cable (42nH/ft) raCK M ouNT KITs 4288-1 S ingle Fixed Rack Mount Kit 4288-2 D ual Fixed Rack Mount Kit IEEE-488 I NTE rfaCEs KPCI-488LPA I EEE-488 Interface/Controller for the PCI Bus KUSB-488B I EEE-488 USB-to-GPIB I nterface Adapter sEr VICEs aVaIl ablE 2303-3Y-EW 1 -year factory warranty extended to 3 years from date of shipment 2303-PJ-3Y-EW -year factory warranty extended to 3 years from date of shipment 2304A-3Y-EW -year factory warranty extended to 3 years from date of shipment C/2303-3Y-ISO 3 ( ISO-17025 accredited) calibrations within 3 years of purchase for Models 2303, 2303-PJ* C/2304A-3Y-ISO 3 ( ISO-17025 accredited) calibrations within 3 years of purchase for Model 2304A* *Not available in all countries Model 2303/2304a bl ock Diagram showing DC D VM measurement capability DVM Vout Vin 0–20V DC 2303, 2304a High Speed Power Supplies Fast transient response power supplies Fast transient response power supplies
