The N4220B is the latest version of the PCI Express Analysis Probe and is a replacement for the N4220A.

The N4220B packet analysis probe with option 210, adds packet-based trigger and display for a PCI Express bus. With this probe you can capture and view data traveling across PCI Express at full frequency (2.5+GT/s) in high-level format for viewing on the 16700 or 16900 Series logic analysis system. The tool decodes the 8b/10b encoded and scrambled PCI Express data to present a packet-based listing.

The N4220B PCI Express analysis probe decodes a number of pre-defined PCI Express packets and also allows for user-defined packet setup. You can describe your trigger at the packet level.

All PCI Express traffic is time-stamped in the logic analyzer for time-correlation measurements with other system buses such as a µProcessor system bus (FSB), memory interface, Serial ATA, etc.
