The U7232A allows you to select

a test mode that suits your goals.

The selection offers the choice of

compliance testing, user-defined

testing and targeted characterization.

The `Compliance conditions

only’ mode is a test process that

is controlled by a configuration

control that is in accordance with

the DisplayPort compliance test

specification. This assures the user

that measurements will only be

performed on those configurations

required to be tested. For instance,

the data eye only need be measured

for 800 mVolt setting, at both bit

rates, with no pre-emphasis; only

those conditions will be used for eye

measurement in the `compliance

conditions only’ mode.

Device definition

Critical information to guide the test

process will be the device capability

information. This is information about

the test device such as the valid

levels, pre-emphasis settings, number

of lanes, bit rates and whether spread

spectrum clocking is enabled or not.

These capabilities are identified in the

DUT definition screen in Figure 4.
