72 U7232A DisplayPort Compliance Testing Notes
8 Source Pre-emphasis Level Verification Testing
Probing for Pre-emphasis Level Verification Testing
When performing the pre- emphasis level verification test, the DisplayPort
Electrical Performance Compliance Test Application will prompt you to
make the proper connections. Your DisplayPort test environment setup on
the Set Up tab must match the physical connection. There are two modes
that you can use to configure the Set Up tab: Wizard Mode and Manual
Mode. The Wizard Mode leads you step by step through each of the
different setup choices with a description of what the choices do. The
Manual Mode allows you to choose only those set up choices that you
want to make without going through every possible choice of settings.
For example, if your test environment setup is similar to Figure 25 below:
two Connection by using W2641A Test Fixture, then your physical
connection for the pre- emphasis level verification test should be similar to
Figure 26.
