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 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.

摘要： A system, method and article of manufacture are provided for facilitating user interface roaming in an interface roaming network framework. Received from a wireless link is a list of usable interface clients in proximity to the wireless link. Each usable interface client has functional capabilities associated with it. One of the interface clients is selected from the list and the wireless link is notified of the selected interface client. A connection is then initiated with the selected interface client and an application is executed based on the capabilities of the selected interface client in order to generate content. The generated content is then transmitted to the interface client so that the content may be displayed using the interface client.

摘要： A method for improving accuracy of power measurements of low power radio frequency (RF) signals received by a RF signal receiver in which power measurement accuracy taken at a low resolution is compensated with use of multiple RF signal attenuations at a finer resolution. In accordance with exemplary embodiments, incremental RF signal attenuations are applied to the received RF signal. An average of the power measurements, including those with the applied signal attenuations, has a net measurement error less than that of a direct power measurement.
