摘要： A test system for testing a device under test (DUT) is provided. The test system may include a DUT receiving structure configured to receive the DUT during testing and a DUT retention structure that is configured to press the DUT against the DUT receiving structure so that DUT cannot inadvertently shift around during testing. The DUT retention structure may include a pressure sensor operable to detect an amount of pressure that is applied to the DUT. The DUT retention structure may be raised and lowered vertically using a manually-controlled or a computer-controlled positioner. The positioner may be adjusted using a coarse tuning knob and a fine tuning knob. The positioner may be calibrated such that the DUT retention structure applies a sufficient amount of pressure on the DUT during production testing.

摘要： A test system for characterizing an antenna tuning element is provided. The test system may include a test host, a radio-frequency tester, and a test fixture. The test system may calibrate the radio-frequency tester using known coaxial standards. The test system may then calibrate transmission line effects associated with the test fixture using a THRU-REFLECT-LINE calibration algorithm. The antenna tuning element may be mounted on a test socket that is part of the test fixture. While the antenna tuning element is mounted on the test socket, scattering parameter measurements may be obtained using the radio-frequency tester. An equivalent circuit model for the test socket can be obtained based on the measured scattering parameters and known characteristics of the antenna tuning element. Once the test socket has been characterized, an equivalent circuit model for the antenna tuning element can be obtained by extracting suitable modeling parameters from the measured scattering parameters.

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 chamber with multiple antennas, and radio-frequency (RF) cables that connect the test unit to the multiple antennas within the test chamber. Reference devices under test (DUTs) may be used to calibrate the OTA path loss of each test station while switching one of the multiple antennas into use one at a time at desired frequencies. A preferred antenna list indicating the preferred antenna that provides the optimal path loss for each desired frequency may be generated. Once calibrated, the test stations may be used during product testing to test factory DUTs to determine whether a particular production DUT satisfies pass/fail criteria. During product testing, a selected one of the multiple antennas is enabled based on the preferred antenna list to perform desired measurements.
