Analyzing Multiple Waveforms
Waveform Analysis Menu
1.
From the top menu, select
OTDR
.
2.
Press the
Advanced Analysis
soft key to display the Advanced Analysis menu.
Multi trace analysis
Up to four waveforms can be displayed and compared.
2-way trace
Waveforms of a measurement target measured from each end
can be combined.
Section analysis
Each item can be measured with the location that is specified as
the start point within the specified section as the reference point.
Performs macro bending
Bending loss events can be displayed on the screen. See section 4.2.
Displays the differential trace
You can load two waveforms that have been measured on the
AQ7280 and display their difference as a waveform.
Multi Trace Analysis
Press the
MultiTrace
soft key to display the MultiTrace menu.
Traces 1 to 4
Load, clear, and move
traces.
Selects the current trace
(Trace1, Trace2, Trace3, Trace4)
Select the trace you want to place
the cursor on.
Load waveform data.
The file operation screen will appear.
See section 6.3.
Clears the displayed traces
Clears the display of the loaded traces
Moves the trace up
Moves the display position of
the loaded trace up.
Moves the trace down
Moves the display position of
the loaded trace down.
Loading Waveform Data
Up to four traces can be loaded. Loaded traces are displayed on a single screen, so you can
compare them. The type of file that you can load is SOR. Loaded traces are displayed according to
the current trace scale. They are displayed at the 0 m position on the horizontal axis or so that their
distance references match that of the current trace. Each loaded trace can be shifted vertically as
you like.
