Analyzing Traces and Events
OTDR 163
Inserting Events
3. Select the location where you want to insert an event.
Four markers are available to measure the inserted event, but only
marker A identifies where the event will be inserted. Use one of the
following methods:
³ Enter the location of the new event in the Location box.
³ Use the marker arrows to move marker A on the trace display.
4. Once you have determined the location, press the Event Type button.
5. Press the button corresponding to the desired event type.
Loss and reflectance are calculated automatically, based on the
position of the markers. You may enter the event loss and reflectance
values in the appropriate boxes.
6. Press OK to insert the event or Cancel to return to the events table
without making any changes.
Inserted events are marked with asterisks (appearing beside the event
number).
