38 Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual
4. For multi‐lane PCI Express links, 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.
4.10.1 Stopping a Recording
You can stop the recording process at any time by pressing the Stop button . This
causes the Analyzer to stop the recording and upload the CATC Trace to the host machine.
If you press the Stop button again, the Analyzer temporarily halts the upload process and
opens the following dialog box.
Figure 4.10: Abort Upload
This dialog presents options for stopping, continuing, or aborting the upload:
 Stop: Aborts further CATC Trace upload and displays whatever data that has
already been uploaded.
 Continue: Resumes the upload. This command tells the Analyzer to finish
uploading whatever CATC Trace data is still in its buffer.
 Flush: Flushes the CATC Trace without saving or displaying it.
If you allow the traffic data to be uploaded, it is automatically saved on the host
machine’s hard drive as a file named data.pex or the name you assign as the default
filename in the recording options.
