Inserting Events
You can insert events in the event 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 78).
You can add this event to the events table manually. This will add a number
on the trace at the location of the insertion, but it will not modify the trace.
To insert an event:
1. From the main window, select the Graph tab and press the Event
button.
2. From the Event pane, press Insert.
