Explanation
Multi Trace Analysis
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 in line with the current trace. 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.
Current Trace
You can select the current trace from Trace 1 to Trace 4.
When you expand or reduce the current trace, other traces are adjusted accordingly.
Cursors are displayed on the current trace. Distance and splice loss that are displayed in the marker
information are those of the current trace.
2 way Trace Analysis
Loading Waveform Data
The type of file that you can load is SOR.
Traces that meet the following conditions can be combined.
• Event lists are available.
• The wavelengths and pulse widths of the two traces are the same.
• The distances from the measurement reference (S) to the end event (E) are the same.
Current Trace
The current trace can be set to one of the combined traces.
Cursors are displayed on the current trace.
Waveform Display of 2 Way Trace Analysis
The horizontal axes of the combined traces are aligned so that the end point of the Trace1 (in the
end A to end B direction) match the 0 m position (distance reference) of the Trace2 (in the end B to
end A direction).
