摘要： A digital communications test system and method for testing a plurality of devices under test (DUTs) in which multiple sets of a single vector signal analyzer (VSA) and single vector signal generator (VSG) can be used together to perform error vector magnitude (EVM) measurements for one or more DUTs in parallel, including one or more of composite, switched and multiple input multiple output (MIMO) EVM measurements. This allows N pairs of a VSA and VSG to test N DUTs with N×N MIMO in substantially the sane time as a single VSA and VSG pair can test a single DUT, thereby allowing a substantial increase in testing throughput as compared to that possible with only a single VSA and VSG set.

摘要： A system and method for initiating testing of a plurality of communication devices. The tester and devices under test (DUTs) are first synchronized as a way of confirming test readiness on the part of the DUTs, Following that, a test sequence is initiated by the tester. The synchronization and test initiation can be accomplished using signals with differing signal magnitudes or device identifiers. The test sequence can be a DUT transmit signal test in which each DUT transmits data packets in accordance with one or more predefined test sequences. Alternatively, the test sequence can be a DUT receive signal test in which the tester transmits data packets to the DUTs with differing signal frequencies or signal magnitudes.

摘要： A test equipment for testing a wireless communication device includes a wireless transceiver, memory, and a controller. The wireless transceiver transmits a first and second series of packets. The wireless transceiver receives a power level indicator that is based on at least one of the first series of packets. The memory stores the power level indicator. The controller performs a signal strength test. More specifically, the controller controls the transceiver to transmit the first series of packets at a first power level. The controller stores the power level indicator in memory when the power level indicator is received by the transceiver. The controller controls the transceiver to transmit the second series of packets at a second power level.
