Analyzing Traces with the Bidirectional Analysis Application (Optional)

Inserting Events
Inserting Events
Note: You can only create events for the A->B or B->A trace (not for the
bidirectional measurement). The application regenerates the bidirectional
measurement automatically to take into account the modifications you
have made.
You can insert events in the events table manually.
This could be useful, for example, if you know that there is a splice at a
given location, but the analysis does not detect it because it is hidden in the
noise or because the splice loss is lower than the minimum detection
threshold (see Setting Pass/Fail Thresholds on page 245). If you create this
event, the application will add a number on the trace at the location of the
insertion, but it will not modify the trace.

Inserted events are removed when you reanalyze a trace.
