I have been SerDes Wizard to test a diff pair.
Bellow is a list of steps:
1. Open a board file
2. Defined a pair under test as a diff pair using the "differential Pair" tab
3. Started the wizard, selected the pair, selected the protocol - 10KR
4. Run the test
Test has a couple failings. One of them - Near End Cross talk Mask.
I believe that according to the 10KR standard, a near end is defined as a crosstalk interference between the two diff pairs.
I don't understand why the Near End reported in a case where the only one diff pair is defined.
It is possible I am missing something.
