    摘要： Wireless test equipment may be used to perform over-the-air testing of user equipment. The user equipment may contain an antenna and a receiver. The wireless test equipment may contain a call box that performs network-level testing by sending and receiving protocol-compliant network messages. The call box may transmit a radio-frequency test signal at a predetermined power. The antenna in the user equipment may receive the radio-frequency test signal and may provide the received radio-frequency test signal to the input of the receiver. The call box may send a network message such as a code-division-multiple-access intercode handover command to the user equipment to direct the user equipment to measure the received radio-frequency test signal power at the input of the receiver. The measured power may be transmitted to the call box as part of a pilot measurement message indicator, using an intercode handover command, or using other network messages.

    摘要： A test station may include a test host, a test unit, and a test chamber. Multiple devices under test (DUTs) may be placed in the test chamber during wireless testing. Radio-frequency signals may be conveyed between the test unit and the multiple DUTs using a conducted arrangement through a splitter-combiner circuit or using a radiated arrangement through a test antenna in the test chamber. The multiple DUTs may be synced to the test unit one DUT at a time (in series) or in parallel. The test host may direct the test unit to broadcast downlink signals at a given channel. The test host my direct a selected DUT to transmit uplink signals at the given channel or at a selected channel that is different from the given channel. The test unit may be used to perform desired measurement on the uplink signals transmitted from the selected DUT.

    摘要： A device under test (DUT) may be tested using a test station having a test host, a non-signaling tester, and a test cell. During testing, the DUT may be placed within the test cell, and the DUT may be coupled to the test host and the tester. In one suitable arrangement, the DUT may be loaded with a predetermined test sequence. The predetermined test sequence may configure the DUT to transmit test signals using different network access technologies without synchronizing with the tester. The tester may receive corresponding test signals and perform desired radio-frequency measurements. In another suitable arrangement, the tester may be loaded with the predetermined test sequence. The predetermined test sequence may configure the tester to generate test signals using different network access technologies without establishing a protocol-compliant data link with the DUT. The DUT may receive corresponding test signals and compute receive signal quality.
