Comprehensive transmitter characterization of USB 3.1 Gen 2

...In conjunction with USB 3.1’s promulgation, a new connector — USB Type-C — has been introduced. Its ALT mode capability enables it to transmit not only USB signals, but also Thunderbolt, DP, and MHL signals over the same connector.

This article, which focuses on how to perform transmitter characterization for next-generation USB, exemplifies the type of careful testing that Gen 2 needs. But bear in mind that any complete characterization of a USB 3.1 link requires other test systems, including EDA design simulation tools, BERT custom-link training and receiver test solutions, and network analyzers for characterizing the cables and connectors....

And so on. Not a comprehensive description, but with some details such as the connector pinout, etc.

This too may be an important bit of knowledge about USB-C cables for safe-guarding your new equipment.

And an article on making wise choices for USB-C

Hope this is helpful
