A method for contemporaneously testing multiple digital data packet transceivers using predefined UL test sequences of synchronized data packets by pre-configuring test measurements, and multiplexing and interleaving portions of the data packets from the devices under test (DUTs).

System and method for testing multiple digital signal transceivers in parallel

Apparatus and method for testing signals from two or more OFDM transmitters simultaneously with a single VSA.

Apparatus and method for simultaneous testing of multiple orthogonal frequency division multiplexed transmitters with single vector signal analyzer

A signal analyzer and method for measuring signal compression levels of one or more individual orthogonal frequency division multiplexed (OFDM) signals among a plurality of OFDM signals within a composite signal.

Power line communication ('PLC') signals are transmitted between a head-end PLC transceiver coupled to multiple remote PLC transceivers over a electric power and communications distribution network in accordance with a timing controlled PLC data frame which determines how much bandwidth is allocated to downstream transmission from the head-end to the remotes and to upstream transmissions from one or more of the remotes to the head-end. The configuration of the timing controlled data frame can be dynamically modified to achieve higher bandwidth for the downstream traffic and to satisfy changing bandwidth needs of each remote.

Method and system for timing controlled signal transmission in a point to multipoint power line communications system

Data throughput rate in a power line communications ('PLC') system is controlled by generating PLC carrier signals in accordance with a PLC signal frame structure containing payload symbols where the payload symbol length is selected based on at least one of a PLC system channel quality and node configuration data. The selected payload symbol length determines the processing operations that a source PLC transceiver performs for generating PLC signals or that a destination PLC transceiver performs for extracting information content from received PLC signals. The payload symbol lengths can be selected to maximize the data throughput rate while maintaining compatibility with prior art PLC system protocols and standards that require a PLC signal frame structure and its payload portion to have fixed, predetermined lengths.

Method and system for maximizing data throughput rate in a power line communications system by modifying payload symbol length

Fault detection and power network quality monitoring are performed for a power line network using power line communications ('PLC') signal transceiving and data processing capabilities. Power line signals are continuously received and processed to obtain signal data representative of power line network operating conditions that are expressed in the received power line signals. The harmonic content and noise signature of the signal data are evaluated with reference to known fault signature data and power line network topology properties for detecting and identifying the location of an existing or anticipated fault in the power line network and assessing power transmission quality of the network.
