5.11.1 Bit Tracer 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.
This option does not have Simple Mode and Advanced Mode. Therefore, Upload Size,
Save as Multisegment Trace, the Miscellaneous options are not available.
Leaving all the boxes unchecked results in no trigger in that direction. For more information,
see the next chapter,
“BitTracer Recording” on page 163 .
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 52: 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.
