Up to 12.0 Gbit/s per lane

As modern video interfaces can transfer data up to 12.0 Gbit/s per lane, it is crucial that the cables are up for the challenge. Only with proper test tools you can make sure your cables work seamlessly with different type of transmitter and receiver devices in the market.

What to Test in Cables?

As modern cables need to be able to transfer video up to 10K resolution it is crucial to test that they take the heavy load and transfer video stream flawlessly. For example, it is possible that a defected or a poor quality cable can transfer 4K video but will struggle to transfer 8K content. Using a monitor to test cables is not sufficient as modern monitors have high-quality receiver chips that can rectify a defected signal. Even if a monitor shows the video without problems it does not guarantee that the video is shown on all monitors. Also, a consistent and flawless analysis of the quality of the video is not possible to do with the human eye.

With Unigraf’s easy-to-use GUI delivered with all UCD series test tools you can easily monitor Link status on all four lanes. Link status bars and information of the streamed video show crucial information on the quality of the link provided by the cable.

The video below shows link monitoring feature of UCD Console GUI. You can see the unstable link in lanes 0 and 1 from the error counter and the red color of the link status.

Automated Cable Testing

Testing of USB-C, DisplayPort and HDMI cables can also be automated by using test automation scripts. These scripts are part of Unigraf’s TSI SDK which is a common test automation platform for all UCD-series test tools. TSI SDK is delivered with each UCD series test tool. It comes with an application designed specifically for cable testing. The application tests link quality based on link training parameters and link error counters on each active lane.
