Keithley Model 2306 Dual-Channel Battery Charger/Simulator The dual-channel Model 2306 Battery/Charger Simulator was designed specifically for development and test applications of portable, battery-operated products, such as cellular and cordless telephones, mobile radios, and pagers Includes Accessories As Listed Above! Working Condition: Excellent Condition: Refurbished Calibrated: Yes Warranty: 90 Day Exchange Warranty Keithley 2306 Battery Charger/Simulator The dual-channel Model 2306 Battery/Charger Simulator was designed specifically for development and test applications of portable, battery-operated products, such as cellular and cordless telephones, mobile radios, and pagers. These precision power supplies have ultrafast 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 2306’s battery-simulator channel can be programmed to operate like a discharged rechargeable battery, sinking current from a separate charger or from the Model 2306’s charger-simulator channel. Maximize Test Throughput with Accurate Battery Simulation The battery-output channels of the 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 power the device during actual use. The output resistance of the Model 2306’s battery channel can be programmed (with 10m? resolution) over the range from 0? to 1? so that the output resistance can be set to the same level as the output resistance of the battery that powers the device. Portable wireless devices make great demands on their battery power sources. The battery must source load currents that can jump virtually instantaneously from a standby current level (100–300mA) to a full-power RF transmission current level (1–3A). In other words, the load current on the battery can increase rapidly by a factor of 700–1000%. As a result, the battery voltage drops by an amount equal to the value of the current change multiplied by the battery’s internal resistance. The Model 2306 power supplies enable test systems to duplicate this voltage drop by programming their output resistance to be equivalent to that of the battery that will power the device. This allows wireless device manufacturers to test their products under the same power conditions that they will encounter in actual use. In response to large load changes, the battery channel of the Model 2306 have transient voltage droops of less than 100mV and transient recovery times of less than 60µs, 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 reaistic 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. The Model 2306 ensures maximum production throughput when testing portable devices by minimizing false failures, minimizing the number of test setups by performing multi devices by minimizing false failures, minimizing the number of test setups by performing multiple tests with the same power supply, and minimizing test fixture complexity by eliminating the need for voltage-stabilizing capacitors 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, aveage currents, and baseline currents in various operation modes. When testing these devices, these measurements are complicated by the pusating nature of load currents, such as the transmit and receive load currents of digital cellular phones. The Model 2306 can measure the peak and average currents of pulses as short as 60µs and as long as 833ms. Measure Long-Period Waveform Currents For pulse trains with periods longer than 850ms, the Model 2306 offers 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 Model 2306 is 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. Verify Load Currents in All Operating States The Model 2306 employs a unique pulse current step function for measuring the load current at each level of a device’s operational states. For example, if a cellular phone is ramped up and down through as many as 20 discrete power consumption states, the Model 2306 can measure the load currents in synchronization with the current steps. This capability allows a test engineer to verify peformance at each operational state and simultaneously acquire power consumption information. The fast current measure capability is another way the Model 2306 power supply saves test time and production costs. Simulate a Discharged Battery for Charger Testing The Model 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. Open-Sense Lead Detection The Model 2306 has an automatic open–sense lead detection capability, which indicates if there is a broken remote sense lead or an open connection from a remote sense lead to the test fixture. 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. Independent Digital Voltmeter Inputs Many programmable power supplies offer output readback capabilities, but the Model 2306 also offers DVM inputs. Both instruments allow measuring signals from –5V to +30V DC 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. 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. In addition to power control, the 2306 provides extensive measurement capabilities in the same half-rack case. The front panel 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. A minimum of front panel buttons ensures that operation is simple and straight-forward. For additional control requirements, the Model 2306 has four digital relay control outputs and a 5V DC output to power a relay coil.
