摘要： Calibration equipment for calibrating multiple test stations in a test system is provided. Each test station may include a test unit, a test fixture, and a radio-frequency (RF) cable that connects the test unit to the test fixture. A control test setup may be used to calibrate uplink and downlink characteristics associated with each test station (e.g., to determine path loss associated with the RF cable and test fixture and variations associated with the test unit). The control test setup may calibrate each test station at desired frequencies to generate a test station error (offset) table. The test unit of each test station may be individually configured based on the test station error table so that offset is minimized among the different stations and so that the test stations may reliably measure hundreds or thousands of wireless electronic devices during product testing.

摘要： A test station may include a test host, a tester, and a test chamber. Multiple devices under test (DUTs) may be placed in the test chamber during device characterization operations. Radio-frequency signals may be conveyed from the tester to the multiple DUTs using a radiated arrangement through an antenna in the test chamber. The tester may broadcast downlink test signals in parallel to the multiple DUTs. The DUTs may simultaneously synchronize with the downlink test signals and measure radio-frequency performance levels while receiving the downlink test signals. The test host may direct the tester to gradually lower its output power level. The DUTs may be used to determine downlink sensitivity by monitoring the measured radio-frequency performance levels as the output power level of the tester is lowered. Simultaneously downlink sensitivity testing may be performed for multiple modulation schemes and data rates for any communications protocol.

摘要： A test system may include multiple test stations. Electronic devices may be tested using the test system. Each test station may include a test unit such as a radio-frequency tester that can make wireless and wired radio-frequency signal measurements on devices under test. The test stations may be configured to perform pass-fail testing on devices under test during manufacturing. One or more selected devices under test that have passed the pass-fail tests may be retested using the test stations. Multiple tests may be performed at a given test station using the same selected device under test. Gathered test data may be analyzed to determine whether the test stations have sufficient accuracy and precision or need to be recalibrated or taken offline.

摘要： Wireless electronic devices may include wireless communications circuitry such as a transceiver, antenna, and other wireless circuitry. The transceiver may be coupled to the antenna through a bidirectional switch connector. The switch connector may mate with a corresponding radio-frequency test probe that is connected to radio-frequency test equipment. When the test probe is mated with the switch connector, the transceiver may be decoupled from the antenna. During transceiver testing, radio-frequency test signals may be conveyed between the test unit and the transceiver using the test probe. During antenna testing, radio-frequency test signals may be conveyed between the test unit and the antenna using the test probe. Transceiver testing and antenna testing may, if desired, be conducted in parallel using the test probe.

摘要： A test station may include a test host, a signal generator, and a test chamber. Multiple devices under test (DUTs) may be placed in the test chamber during production testing. Radio-frequency signals may be conveyed from the signal generator to the multiple DUTs using a conducted arrangement through a radio-frequency signal splitter circuit or using a radiated arrangement through an antenna in the test chamber. The signal generator may broadcast initialization downlink signals. The multiple DUTs may synchronize with the initialing downlink signals. The signal generator may broadcast test downlink signals at a target output power level. The multiple DUTs may receive the test downlink signals and compute a corresponding downlink transmission performance level based on the received downlink signals. A given DUT is marked as a passing DUT if the downlink performance level is satisfactory. A given DUT may be retested if the downlink performance level fails design criteria.
