USB4 Gen 2-4 Protocol Qualified Triggers

While there is no hardware-based protocol trigger for USB4 Gen 2-4, you can achieve a similar packet trigger by using the standard hardware trigger modes (edge, pattern, pulse, etc.) and then enabling a protocol qualified trigger.

Protocol qualified triggers cause an automatic decode after each hardware trigger (acquisition). If the packet search specification is found in the captured data, the data is displayed; otherwise, the data is not displayed. Then, another run (acquisition) is initiated, and the process repeats.
