DisplayPort Compliance Test Solution - Agilent

Agilent recently introduced its DisplayPort source compliance test solution. The new  solution is designed for use by DisplayPort compliance test labs and by engineers designing DisplayPort devices who want to optimize their devices before they submit them to a DisplayPort compliance test lab for certification. The Agilent solution supports DisplayPort tests as specified in the DisplayPort specification 1.1 and accommodates the requirements of the compliance test specification that is expected to be released in the near future.

About DisplayPort standard (main source: wikipedia.org)

The DisplayPort standard defines a high-bandwidth interface for connecting laptops or personal computers with display monitors or connecting computers with high-definition consumer electronics devices.

DisplayPort is a new digital display interface standard, defining a new license-free digital audio/video interconnect, intended to be used primarily between a computer and its display monitor, or a computer and a home-theater system.

The DisplayPort digital display specification 1.1 was published by the Video Electronics Standards Association (VESA) and is being endorsed by major PC manufacturers such as Dell and Hewlett-Packard Company.

DisplayPort key specs:

• 10.2 Gbit/s forward link channel supports high resolution monitors, 2560×1600, with single cable.
• Full bandwidth transmission for 3 meter cable.
• Open and extensible standard to help with broad adoption.
• Supports color depth of 6, 8, 10, 12 and 16 bits per component.
• Reduced bandwidth transmission, 1080p, for 15 meter cable.
• 128-bit AES DisplayPort Content Protection (DPCP) support, and support for 40-bit High-bandwidth Digital Content Protection (HDCP) from version 1.1 onwards.
• Supports internal and external connections so that one standard can be used by computer makers reducing costs.
• DisplayPort connector assists in blind connection by just feeling.

DisplayPort supports full bandwidth transmission over 3 meter (10ft) cable, and a maximum of 1080p resolution at 24bpp, 50/60Hz over a 15 meter cable.

DisplayPort includes optional DPCP (DisplayPort Content Protection) copy-protection from AMD, which uses 128-bit AES encryption, with modern cryptography ciphers. It also features full authentication and session key establishment (each encryption session is independent). There is an independent revocation system. This portion of the standard is licensed separately. It also adds support for verifying the proximity of the receiver and transmitter, a technique intended to ensure users are not bypassing content protection system to send data out to distant, unauthorized users.

The solution includes Infiniium DSO80000 Series oscilloscopes, U7232A DisplayPort compliance test software and a W2641A DisplayPort test point access adaptor.

Agilent DisplayPort is available with price starts at US$95,000
