Key Features

Test 8K

UCD-424 is interface test unit for verifying DisplayPort™ Alternate mode over USB-C™ up to 8K@30 Hz and 4K@120 Hz video modes. The device gives you control for USB-C data and power roles. It is a flexible and robust tool either via a GUI on a laboratory desktop or via automated functional tests. The associated software provides the user access to the vital parameters and controls needed when evaluating the various functions of the interface.

For R&D and Test Automation

UCD-424 supports both hands-on debugging and running extended automated test sequences. UCD Console GUI is a preview and test application for desktop use. Each interface function has a wellstructured dialog for superior at-a-glance viewability.

Unigraf TSI is a test software API that provides the system integrator a fast and reliable way for ensuring the functionality of the tested equipment.

Validation Tool

UCD-424 is a Compliance Test Tool for testing DisplayPort 1.4a Link Layer CTS on Sinks and Sources. The device is also capable of HDCP 2.2 and 2.3 CTS on Transmitters and Receivers. The unit supports FEC, DSC Sink and LTTPR. Please contact Unigraf for details.



Key Benefits

Reliable Compliance Testing Tool

DisplayPort 1.4a Link Layer Compliance Testing

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.

HDCP 2.3 Compliance Testing

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.
