17 Link Layer Protocol Tests

Probing for Link Layer Protocol Tests

When performing the link layer protocol 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.

Figure 46 below shows the single- ended connections for Link Layer

Protocol Tests.

You can use any oscilloscope channel and connect it to any lane test point.

You select the channels used for testing lanes in the Set Up tab of the

DisplayPort Electrical Performance Compliance Test Application.

The data lanes and channels shown in the previous figure are just

examples. You can choose any desired data lane and channel that you

want.
