Saving CATC Trace Files Teledyne LeCroy
4.12.1 CATC Trace Files
PETracer records PCI Express traffic into a CATC Trace file with the default name data.pex
or any other that you specified in the Recording Options. This file is overwritten with new
data each time PCI Express traffic is recorded.
When Multisegment CATC Traces are created, a special index file is also created called
<filename>.pem. This index file provides a high level view of the CATC Trace segments
created in the recording session.
If you want to save a CATC Trace, use the File > Save As function. This option allows you to
save the current CATC Trace to a unique file name, thereby ensuring that it is not
overwritten. This option also allows you to save a range of packets in a CATC Trace file.
You can pre‐define the name of the recorded CATC Trace file using the Trace Filename and
Path option in Recording Options.
4.12.2 Recording Options Files
Recording Options files are created when you set recording options. These files use the
.rec extension and contain recording option information.
4.12.3 Display Options Files
Display Options files are created when you set display options. These files use the .opt
extension and contain the display options information.
4.13 Saving CATC Trace Files
4.13.1 Using the Save As Function
When you record a CATC Trace file, the Analyzer software provides a pre‐defined name to
the CATC Trace file (data.pex or any other that you specified in the Recording Options). If
you do consecutive recordings, each time the previous recording is overwritten. If you see
a recording you want to analyze later, you need to give a unique name to the CATC Trace
file, so it is not overwritten with the next recording.
Also, when you analyze a recorded CATC Trace file, you might be interested in preserving
just a part of the PCI Express traffic that was recorded. If you save a portion of a CATC
Trace file, it can get significantly smaller, allowing you to attach it to an e‐mail.
To save a portion of a CATC Trace file or the whole file to a unique name, select Save As
from the File menu (see
Figure 4.11 on page 48 ).
