Abstract: A system and method of providing driver software to a test controller to facilitate testing by a wireless transceiver tester of a device under test (DUT).

Further accessed are executable driver instructions, including a plurality of executable driver program instructions for driving at least one of the wireless transceiver tester and the DUT, which are communicated to the test controller.

Abstract: A system and method for testing a data packet signal transceiver in which multiple network addresses (e.g., media access control, or MAC, addresses) are used to establish synchronization of the device under test and the test equipment controlling the test. In accordance with an exemplary embodiment, synchronization is established using a first MAC address, following which testing is conducted using a second MAC address.

Abstract: 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.

Abstract: 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.

Abstract: A test equipment for testing a wireless communication device includes a wireless transceiver and a controller. The wireless transceiver transmits a first series of packets while operating in a first mode. The wireless transceiver transmits a second series of packets while operating in a second mode. The wireless transceiver receives acknowledgment packets. The controller controls the transceiver to transmit the first series of packets. The controller counts the acknowledgment packets received by the transceiver in response to transmitting each of the first series of packets. The controller controls the transceiver to transmit the second series of packets when the count exceeds a predetermined count.
