Tests performed
The U7232A DisplayPort electrical
performance validation and compliance
software performs all the required
tests and many of the informative ones
as listed in the DisplayPort Compliance
Test Specification 1.1 (CTS1.1) as
documented in section 3.5.3 of the
base specification.
Note that the U7232A DisplayPort
test software can make other
measurements not included here, such
as receiver eye measurements and
equalized eye measurements as well
as most of the newly omitted
CTS 1.1 measurements.
