    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 for testing a communication device includes a testing module, a measurement module, and a control module. The testing module transmits one or more first test signals based on a first test sequence. The measurement module acquires test data by receiving one or more second test signals that are based on the one or more first test signals. The control module initiates the first test sequence in response to receiving a start test signal from an analysis system. The control module transfers the test data to the analysis system in response to a transfer data request. The control module initiates a second test sequence while the analysis system is analyzing the test data. The testing module generates and transmits one or more third test signals based on the second sequence when the second test sequence has been initiated.

    摘要: A system and method for facilitating comparison of radio frequency (RF) data signals transmitted by a device under test (DUT) and received by a test system. A RF data signal received from a DUT is analyzed to provide analysis data indicative of conformance of the DUT operation with one or more applicable signal standards. The RF data signal is also converted to related conversion data that can be stored with state machine data corresponding to states of the signal testing subsystem. This state machine data can then be processed as needed with the analysis data and conversion data for off-line tasks such as debugging new test programs and procedures.

    摘要: A method and system for testing a wireless data packet transceiver as a device under test (DUT) adapted to operate in conformance with a wireless signal standard such that a transmitted signal, when received by an intended receiver, is to result in a responsive signal transmission acknowledging such signal reception. During testing, responsive signal transmissions, e.g., acknowledgement signals, are withheld by the test system until after a predetermined number of data packets have been captured from the DUT, until a predetermined time interval has passed, or until data packets at a predetermined number of data rates have been captured from the DUT.

    摘要: A method and system for testing multiple data packet transceivers together during a predetermined time interval. A sequence of downlink data packets are generated and distributed as corresponding sequences of downlink data packets for reception by multiple data packet transceivers each one of which is responsive during at least a respective portion of a predetermined time interval to a respective one of the corresponding sequences of downlink data packets by transmitting a respective one of multiple corresponding sequences of uplink data packets. At least a portion of each of the corresponding sequences of uplink data packets are combined to provide a sequence of test data packets of which at least one signal parameter is measured.
