Just like any other DisplayPort device, devices with USB-C DisplayPort Alternate Mode capability need to be tested for DisplayPort compliance. UCD-424 supports DP 1.4a Link Layer CTS including DSC testing on Sinks, Sources and Branches. Certification from VESA on the Link Layer CTS tests for UCD-424 is pending.
VESA requires HDCP testing as part of the DisplayPort testing requirement for certification. If a DisplayPort receiver or transmitter supports HDCP (as reported in the product CDF) it shall be tested as part of the certification requirements for obtaining the DisplayPort Logo. (Source: VESA)
UCD-424 supports HDCP 2.3 compliance testing on USB-C DP Alt Mode Transmitters, Receivers and Repeaters. The official approval of HDCP 2.3 CTS testing for UCD-424 from DCP is pending.
Unique Features
DisplayPort Entry From Any Role
UCD-424 can enter to DP Alt Mode with any DP Alt Mode partner. Enter DP Alt Mode from any state and controls to swap roles is possible.
UCD Console GUI:
The UCD Console GUI is the dedicated software that enables users to access the test features of the UCD-424 and is supported for Windows, macOS, and Linux. The software provides the user with a flexible way of navigating between the interface based roles of the device and functionalities of each role. The UCD Console features a preview window for the received video and audio, while also monitoring the controls of the link parameters and built-in pattern generator in UCD-424. Users can also have access to an EDID editor and control of the HDCP function.

LTTPR (Link Training Tunable PHY Repeaters):
LTTPR is a feature that helps maintain signal integrity between DisplayPort Source and Sink by letting each repeater optimize the signal path with link training. UCD-424 is able to act as a DisplayPort source controlling the LTTPRs in the downstream signal path. LTTPR Test is a software addition for the UCD-424.
