Analyzing Traces with the Bidirectional Analysis Application
OTDR 231
Modifying Events
Modifying Events
Note: You can only modify the events of the A->B or B->A trace (not those of the
bidirectional measurement). The application regenerates the bidirectional
measurement automatically to take into account the modifications you
have made.
You can change the position as well as the loss and reflectance (reflective
events only) of almost any existing event except:
³
launch event (You can modify the loss and reflectance values, but not
its position. The launch event position must always remain set to 0.)
³
continuous fiber
³
end of analysis
³
merged events
Note: If you want to modify the attenuation value of a fiber section, see Changing
the Attenuation of Fiber Sections on page 237.

MPORTANT
If you reanalyze a trace, all of the modified events will be lost and
the events table will be re-created.
