Configurability and Guided

Connections

The DisplayPort Electrical Performance

Validation and Compliance software

provides flexibility in your test setup.

It guides you to make connection

changes with hookup diagrams when

the tests you select require it. For

test parameters such as bandwidth,

you can select appropriate values. For

more critical parameters, such as mask

scaling option or number of edges for

analysis, default values are tied to the

compliance standard; these values can

only be altered in the debug screen.

In Figure 7 you can see the selection

for various eye mask test functions.

The default for compliance mode is

“Fixed” which places the mask in the

center of the eye per the DisplayPort

Compliance test specification (shown

is ‘Find Margin,’ which will find the

range of passing conditions).

Note: For HBR2 the eye diagram

testing is different from RBR and HBR

as it comprehends 10

–9

BER limits;

so the ‘Find Margin’ capability is not

available.

After you configure the test to meet

your needs, the DisplayPort EPVC

software user interface displays the

connection screen, which is specific

to the configuration data you have

selected. Figure 8 illustrates the

typical connection guidance provided

for a one channel “A minus B” single-

ended connection model for a one lane

test setup.

Figure 8. The final step before test is to illustrate the anticipated connection for the test.

Figure 7. The Configure Tab enables changing measurement parameters in the ‘Debug’

mode to support characterization and debug activities.
