Changing the Loss and Reflectance of Events

Changing the Loss and Reflectance of Events

You can change the loss and reflectance of almost any existing event
except:

continuous fiber

³

end of analysis

³

launch level

³

merged events

³

reflective end

³

total events

In the case of a reflective event, you can also specify whether the event
corresponds to an echo, a possible echo, or if it really is a reflective event.

Note: If you want to modify the attenuation value of a fiber section, see Changing

the Attenuation of Fiber Sections on page 165.

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