3. In the Link section, specify the lane width of the PCI Express link to be analyzed. The
rest of the settings in this section can be left at the factory defaults for most
PCI Express systems.
4. For multi‐lane PCI Express links, when using Auto options, the Analyzer needs to
observe link training in order to record link traffic correctly. If link training (or re‐
training) is not easily controllable for the devices under test, the Analyzer includes
the capability to force link training by disconnecting and reconnecting the
PCI Express link.
Note: For x1 PCI Express links, it is not necessary for the Analyzer to observe link training in
order to record link traffic; this step may be skipped.
5. Click OK at the bottom of the Recording Options dialog to apply the Analyzer
recording settings specified.
6. Click the Record button.
