The several traces are displayed in the same windows and can be used as in the
overlay trace mode (see "Overlay trace function" on page 5-28).
Example of acquisition on two wavelength
Detection of traffic

is fitted with a traffic detector which, in this case, displays a
message indicating the presence of a signal in the fiber being tested. You must
