Controlling a device under test through the DisplayPort connector only, Agilent Technologies’ and Quantum Data’s W2642A AUX channel controller fully automates physical layer testing of the DisplayPort main link for sink- and source-device testing. Automated physical layer tests can be made using Agilent test equipment, such as the DSO90000A Infiniium oscilloscope or the N4903A J-BERT, with the N5990A test automation software. The instrument can control the state of a DisplayPort source or sink device for verification of data exchange over the DisplayPort AUX channel. The device can perform link layer and HDCP (High-bandwidth Digital Content protection) compliance testing. Pricing starts at $86,000.
