摘要： An electronic device may include wireless circuitry such as cellular telephone transceiver circuitry and wireless local area network (WLAN) transceiver circuitry. The telephone transceiver may be used to establish long-range wireless connectivity, whereas the WLAN transceiver may be used to establish short-range wireless connectivity. The performance of the WLAN transceiver may suffer in the presence of heat-generating operations. The performance of the WLAN transceiver may be tested using test equipment while the electronic device is configured in a test mode and a normal user mode. During testing, the WLAN transceiver may be directed to transmit radio-frequency signals while the telephone transceiver is toggled on and off. The test equipment may be used to analyze the radio-frequency signals to measure the transmit power level, transmitter constellation error, transmit spectrum mask, and other performance parameters to determine whether that device under test satisfies design criteria.

摘要： A system for performing wireless local area network testing of wireless devices may include a wireless local area network tester and a device under test. The tester and device under test may communicate over a wireless link. To ensure that the tester accurately analyzes test data, a data rate table is used that specifies fixed data transmission rates to be used by the device under test under both high-quality link conditions and low-quality link conditions. This forces the device under test to transmit control packets at the same high data rate during packet loopback testing, regardless of link quality. When the captured control packets are analyzed at the tester, both low-link-quality data and high-link-quality data may be analyzed using a common test template, ensuring accurate results.

摘要： An offshore firefighting apparatus for subduing an offshore fire includes a vessel; a jet engine coupled to the vessel; and a dynamic positioning system for positioning the vessel. One or more vessels are placed in the vicinity of an offshore fire with the exhaust side of the jet engines pointed toward the fire. As the jet engines are operated, exhaust from the jet engines subdues the fire. The dynamic positioning system on the vessel controls vessel movement during the fire fighting operation.

摘要： A test system for calibrating wireless electronic devices is provided. The test system may include a test host, a radio communication tester, and a temperature chamber in which an electronic device under test (DUT) may be tested. The DUT may include a temperature sensor for monitoring an internal temperature of the DUT and may include power amplifier circuitry for outputting radio-frequency test signals. The tester may be used to measure output power levels of the radio-frequency test signals when the DUT is operating at a given reference temperature and when the DUT is operating at target operating temperature levels other than the given reference temperature. Power amplifier output level offset compensation values may be computed by comparing output power levels measured at each of the target operating temperatures to output power levels measured at the given reference temperature and may be stored in the DUT prior to normal operation.

摘要： Wireless communications circuitry such as radio-frequency power amplifiers may be tested using a test station. A test station may include a test host and a test unit coupled to the test host. The power amplifiers may be configured to transmit radio-frequency signals in allocated resource blocks within a particular radio channel. The power amplifier circuits may be configured to transmit signals utilizing only an allocated portion of its total available resource blocks so that the transmitted signals are output at maximum power levels. The power amplifiers may transmit in resource blocks near a low channel edge during a first time period and may transmit in resource blocks near a high channel edge during a second time period. The test unit may receive the signals generated from the power amplifiers and may perform desired radio-frequency measurements (e.g., test unit may measure adjacent channel leakage radio, signal-to-interference ratio, error vector magnitude, etc.).

摘要： A portable user device may provide Global Positioning System (GPS) services. The device may include a GPS receiver. The GPS receiver may provide accurate information about the current location of the device. A user may use the device to perform tasks. Certain tasks may generate excess heat or de-generate heat that causes the GPS receiver to perform unsatisfactorily. Methods are provided that can test GPS receiver performance during acquisition mode and during tracking mode. During testing, the GPS receiver may be given a predetermined amount of time to acquire a GPS fix. The GPS receiver may be tested repeatedly to acquire successive GPS fixes. After a desired number of tests are performed, a success rate may be calculated. If the success rate is satisfactory, the GPS receiver satisfies design criteria. If the success rate is not satisfactory, the GPS receiver may be reconfigured with new settings.
