The single-channel Model 2302 Battery Simulator and Model 2306 Dual Channel Battery/ Charger Simulator were designed specifically for development and test applications for portable, batteryoperated products, such as cellular and cordless telephones, mobile radios, and pagers. These precision power supplies have ultra-fast transient response so they can have output characteristics identical to actual batteries. These supplies employ a unique variable output resistance so the voltage output can emulate a battery's response (U.S. Patent No. 6,204,647). They provide stable voltage outputs, even when a device-under-test (DUT) makes the rapid transition from the standby (low current) state to the RF transmission (high current) state. In addition, they can monitor DUT power consumption by measuring both DC currents and pulse load currents. The Model 2302 and the Model 2306's battery-simulator channel can be programmed to operate like a discharged rechargeable battery, sinking current from a separate charger or the Model 2306's charger-simulator channel. * Ultra-fast response to transient load currents * Choice of single- or dualchannel supplies * Optimized for development and testing of battery-powered devices * Variable output resistance for simulating battery response (U.S. Patent No. 6,204,647) * Pulse peak, average, and baseline current measurements * 100nA DC current sensitivity * Current step measure function * Sink up to 3A * Open sense lead detection * Built-in digital voltmeter Maximize Test Throughput with Accurate Battery Simulation The battery-output channels of the Models 2302 and 2306 are designed to simulate the output response of a battery. This capability, combined with their fast transient response, makes it possible to power the device during testing in exactly the same way as a battery will Battery 2302/2306 power the device during actual use. The output resistance of the Model 2302 and the Model 2306's RINT ROUT battery channel can be programmed (with 10m resolution) over the range from 0 to 1 so + + that the output resistance can be V V - - set to the same level as the output resistance of the battery that powers the device.

This allows Test Development Software TestPoint wireless device manufacturers to test their products under the same power conditions that they will encounter in actual use. (See Figure 2.)

CS-846) Conventional Power Supplies and Wireless Device Testing During production testing, supplying power to a device that undergoes large, instantaneous load current changes can be extremely difficult. Changes like this force a conventional power supply's output voltage to fall instantaneously. When the power supply's control circuitry senses the error condition (the difference in voltage between the programmed level and the actual level), it attempts to correct or restore the voltage to the programmed level. During this time, the voltage will fall or droop substantially, with the amount of the droop depending on the size of the load current change. The recovery time depends on the transient response of the power supply's control loop. Conventional power supplies will have transient voltage drops of >1V when confronted with load current changes of up to 1000%, and take up to a millisecond to recover to the programmed voltage. For portable devices such as cellular phones that operate at full power for only short intervals, the full power event is over before the conventional power supply can recover. For example, a cellular phone designed to the GSM cellular phone standard transmits and receives information in 576s pulses. If the power supply used to test these types of phones cannot recover quickly enough, the performance of the phone during testing will be compromised by the power supply. If the power supply voltage drops below the threshold of the phone's low battery detection circuitry for long enough, then the phone will turn off during testing, giving a false indication of a failed device. 1.888.KEITHLEY Battery Simulator Battery Charger/Simulators In response to large load changes, the Model 2302 and the battery channel of the Model 2306 have transient voltage droops of less than 100mV and transient recovery times of less than 60s, even when the test leads between the power supply and the DUT are long. This fast transient response, combined with the supplies' variable output resistance, allows engineers to test their portable products under the most realistic operating conditions and eliminate false failures due to conventional power supplies with slow response times (See the sidebar titled "Conventional Power Supplies and Wireless Device Testing".) These supplies also eliminate the large stabilizing capacitors needed at the DUT to compensate for the large droop that occurs when testing with conventional power supplies. By varying the output resistance, which can be done while the output is turned on, test engineers can simulate the operation of different battery types, as well as batteries nearing the end of their useful lives.

Measure Load Currents for Power Consumption Verification or Analysis As manufacturers of portable devices strive to extend their products' battery life, measuring load currents accurately has become increasingly essential in both design and production test in order to ensure the product meets its demanding specifications. Comprehensive testing of these devices requires measuring peak currents, average currents, and baseline currents in various operation modes. When testing these devices, these measurements are complicated by the pulsating nature of load currents, such as the transmit and receive load currents of digital cellular phones. The Models 2302 and 2306 can measure the peak and average currents of pulses as short as 60s and as long as 833ms. (See Figure 3.) Measure Long-Period Waveform Currents For pulse trains with periods longer than 850ms, the Models 2302 and 2306 offer a unique, long integration current measurement mode. This mode can provide an average measurement of a current waveform from 850ms up to 60 seconds long. Measure Low Currents Accurately The Models 2302 and 2306 are based on Keithley's expertise in low current measurement technologies, so they're well-suited for making fast, accurate measurements of sleep and standby mode currents. With 100nA resolution and 0.2% basic accuracy, they provide the precision needed to monitor the low sleep mode currents of both today's battery-operated products and tomorrow's.

Built-in pulse current measurement functions allow test engineers to measure peak, average, and baseline load currents. Simulate a Discharged Battery for Charger Testing The Models 2302 and 2306 can sink up to 3A continuously, just like an electronic load. This allows these supplies to simulate a discharged rechargeable battery for use in testing the performance of battery chargers or battery charger control circuitry. The Model 2306 Battery/Charger Simulator combines the functionality of both the charging current source (the charger channel) and the current sinking to simulate the recharging of a discharged battery (the battery channel) in a single enclosure. (See Figure 5). Fast Turn-On Response for Switchover Simulation When their output is switched on, the Models 2302's and 2306's channels stabilize at the programmed output voltage within 10s. As a result, test engineers can use the Model 2306 to test a battery-operated device's power source control circuitry to verify the device switches from battery power to charger power when the charger is connected. This is particularly important for cellular phone manufacturers who must confirm that the charger can be connected into the phone to power the phone without turning it off during the switchover and inadvertently dropping a call. The Models 2302's and 2306's channels have a high impedance output state when turned off, so external relays are not required in the test system to switch a DUT from the simulated battery to the simulated charger.

To ensure the output voltage does not change from the programmed level, which could cause production devices to be improperly calibrated, the user can set high and low limits around the desired voltage level. Two selectable protection alternatives are available if an overcurrent failure occurs due to a defective DUT or a short in external wiring. The Models 2302 and 2306 can be programmed either to reach a pre-set current limit and stay at that current limit or to turn off the output. 1.888.KEITHLEY (U.S. only) www.keithley.com A Fast transient response power supplies Verify Load Currents in All Operating States The Models 2302 and 2306 employ a unique function (a synchronized step) for measuring the load current at each level of a device's operational states. (See Figure 4). For example, if a cellular phone is ramped up and down through as many as 20 discrete power consumption states, the Models 2302 and 2306 can measure the load currents in synchronization with the current steps. This capability allows a test engineer to verify performance at each operational state and simultaneously acquire power consumption information. The fast current measure capability is another way the Models 2302 and 2306 power supplies save test time and production costs.

Both instruments allow measuring signals from -5V to +30V anywhere in the test system with the same rated accuracy as the voltage readback. The Model 2306 has two sets of DVM inputs; the Model 2302 has one. The DVMs and the power sources can operate simultaneously. For many applications, these built-in DVMs eliminate the expense and space required to add a separate voltage measurement instrument. ROUT + + - Big Functionality in a Small Package For high volume production environments where floor and test rack space are at a premium, the Model 2306 packs two power supplies into one half-rack enclosure.

The front panel display of each unit displays the user's choice of either the output voltage and output current, the average, peak, and baseline pulse current levels, long integration currents, or DC DVM measurements.
