Saving the Span-Start and Span-End
Information
Saving the modified span-start and span-end information allows you to
reapply the current span start and span end of a trace when you reanalyze,
instead of applying the default fiber span originally used for the acquisition.
For details on setting a default span start and end for trace acquisitions, see
Setting a Default Span Start and Span End on page 83.
To save the span-start and/or span-end information or to
deactivate the feature:
1. From the main window, press the Setup button.
2. Go to the Events Table tab.
3. Select the Span Start Memory and/or the Span End Memory boxes.
Note: If you prefer not to save the values, simply clear the Span Start Memory
and/or the Span End Memory boxes.
4. Press Apply to confirm the changes, then OK to return to the main
window.
