Unit Connection Schemes

Unit Connection Scheme 3

Unit Connection Scheme 4

The scheme 1 shows the connection of the analyzer (using one

analyzer’s port) to the network with equipment operating on the Data

Link layer (for example, network switch). In this case, generated test

traffic should be rerouted back to the analyzer via the loopback. At the

DUT, source and destination MAC addresses are swapped in the

incoming packets, and the test stream is retransmitted back to the

source port on the analyzer.
