Agilent Technologies’ W2642A

DisplayPort AUX channel controller

enables fast, easy and automated

testing for the physical layer as well

as flexible debug capability for new

DisplayPort designs. DisplayPort test

and design engineers can now run

physical layer tests fully unattended

thus doubling their productivity.

When used with the W2642A, the

1 The W2642A AUX channel controller is based on the Quantum Data 882E product.

Agilent intellectual property was developed separately and is placed in the 882E to

control the DisplayPort AUX channel .

2 Video Electronics Standards Association (www.vesa.org)

Agilent DisplayPort source and sink

compliance test solutions which are

already VESA

certified for official

DisplayPort compliance testing can

become fully automatic. In addition

to the productivity gains, this new

capability helps eliminate operator

errors and offers complete device test

status tracking and repeatable results.
