Check the listing for details. HP Agilent N4220A Packet Analysis Probe for PCI Express. Condition: For parts or not working. Listed at 350.00 USD. HP Agilent N4220A Packet Analysis Probe for PCI Express *Untested Description The N4220A packet analysis probe for PCI Express 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 Series logic analysis system. The tool decodes the 8b/10b encoded and scrambled PCI Express data to present a packet-based listing. The N4220A PCI Express analysis probe decodes a number of pre-defined PCI Express packets and also allows for user-defined packet setup. 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. Key Features & Specifications Non-intrusive probing of PCI Express slots and chip-to-chip links (link widths: x16, x8, x4, x2, x1) Supports PCI Express at full frequency - 2.5+GT/s Triggering on and decode a PCI Express bus at the packet level Please refer to the datasheet for more information Sold as pictured, no additional software, manuals or accessories provided.
