Figure 11. The final step before test is to illustrate the anticipated connection for

the test.

The U7232A DisplayPort electrical

test 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 reduction or data channel

selection, 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 10 you can

see the selection for various U7232A

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 condition).

After you configure the test to meet

your needs, the U7232A user interface

displays the connection screen,

which is specific to the configuration

data you have selected. Figure 11

illustrates the typical connection

guidance provided for differential tests

for a single lane with an “A minus B”

connection type.

Figure 10. The U7232A configuration screen allows you to alter “soft”

parameters for testing to assist in characterization and debug activities.
