Using MFTP from DUT

The MFTP deskew technique will use the DUT to provide an MFTP signal to C2 and C3 in order to
deskew both channels.

The first step is to connect C2 to Txp on the DUT and C3 to Txn on the DUT. The DUT should be
configured to output a MFTP pattern. The connections to C2 and C3 should include the cables and DC
blocks which will be used during the testing.
