Abstract:
1. A method for testing a data packet transceiver as a device under test (DUT) by communicating pluralities of data packets between one or more test instruments and said DUT, comprising: programming said DUT for loop back operation, wherein a received data packet is decoded to produce decoded data and said decoded data is encoded to produce a corresponding new data packet for transmission; transmitting, with said one or more test instruments, a plurality of sequential test data packets for reception by said DUT, wherein, in correspondence with said programming of said DUT, at least first and second portions of said transmitted plurality of sequential test data packets have at least one of a plurality of mutually distinct signal characteristics including data packet type, transmission power and transmission frequency such that said signal characteristic of said first portion of said transmitted plurality of sequential test data packets is different from said signal characteristic of said second portion of said transmitted plurality of sequential test data packets; receiving, with said one or more test instruments, a plurality of sequential DUT data packets from said DUT, wherein, in accordance with said programming of said DUT, at least first and second portions of said plurality of sequential DUT data packets have at least one of said plurality of mutually distinct signal characteristics such that said signal characteristic of said first portion of said plurality of sequential DUT data packets is different from said signal characteristic of said second portion of said plurality of sequential DUT data packets; and processing said plurality of sequential DUT data packets.
