Teledyne LeCroy Recording Mode
54 Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual
5.11 Recording Mode
There are two options for Recording Mode:
 Protocol Recording
 Bit Tracer Recording
Figure 5.8: Recording Mode Options
5.11.1 BitTracer Recording
When the Bit Tracer Recording box is checked, it allows you to select the Speed and the
Link Width from the drop‐down menu. Based on the Speed and Link Width selected you
can select the Upstream and Downstream Symbol on which to trigger.
This option does not have Simple Mode and Advanced Mode. Therefore, Upload Size,
Save as Multisegment Trace, the Miscellaneous options, Auto‐Configure Lane Polarity,
Auto Speed, and Auto Link are not available.
Note: Leaving all the boxes unchecked results in no trigger in that direction. For more information, see
the next chapter, see the next chapter, “BitTracer Recording” on page 147 .
5.12 Trigger Position
This Trigger Position slide‐bar lets you adjust the amount of recording buffer allocated to
recording pre‐trigger and post‐trigger traffic (see
Figure 5.1 on page 48 : 2F).
Figure 5.9: Trigger Position Slide Bar
For example, if you set the Trigger Position to 90% Post‐Triggering Traffic, the Analyzer
records 10% pre‐trigger traffic and 90% post‐trigger traffic.
Trigger Position is only available when Manual Trigger or Event Trigger is selected.
5.13 Save As MultiSegment Trace
Divides the recording into segments so as to allow very large recordings to easily upload
and view. If you are planning to create a large recording, you might want to test this
option to see how it affects performance. Large CATC Trace files are easier to navigate but
slower to open (see
Figure 5.1 on page 48 : 2G).
