Gen 2 introduced 128b/132b encoding, which is significantly more complex than previous versions. The N8821A software allows engineers to debug and validate their Gen 2 implementations by allowing them to quickly show protocol decode, search with protocol-level triggers, and use time-correlated views to troubleshoot serial protocol problems back to timing or signal integrity. The software will also work with USB Type-C implementations of USB 3.1 Gen 2.
The screen capture sequence shows, in order; Full-screen listing; precise time correlation; quickly find occurrences; trigger and search.
