APPARATUS AND METHOD FOR SIMULTANEOUS TESTING OF MULTIPLE ORTHOGONAL FREQUENCY DIVISION MULTIPLEXED TRANSMITTERS WITH SINGLE VECTOR SIGNAL ANALYZER

摘要

the present invention includes a plurality of orthogonal frequency division multiplexing (OFDM) signal of at the same time to for an apparatus and method for inspection relates, vector signal analyzer 600 may include a plurality of a plurality of OFDM signals to provide the converted data signal and converting the received composite signal through the signal communication path, wherein the data signal includes a plurality of composite signals associated comprises a number of data packets transmitted from a remote signal source having a transmission process, and each having a respective portion of each of the plurality of transmission data of a plurality of preamble data, wherein each portion of the plurality of transmission data is each corresponding to a respective portion of the plurality of signal data related to the number of known signals and each one of the transfer process, the communication path (m), each of the plurality of the converted data signal of the plurality of data packets containing each of, the present invention is the number of known data in order to provide a plurality of inspection data that indicates the size of the error vector associated with the complex data signal, wherein at least respective portions of the plurality of preamble data, the number of The process to receive the at least respective portions of the transmission data.
