Differential Trace
Loading Waveform Data
The type of file that you can load is SOR.
A differential trace of traces that meet the following conditions can be displayed.
• Sample interval
• Measurement start position
Current Trace
The current trace can be set to one of the traces that are used for taking the difference.
Cursors are displayed on the current trace. Distance and splice loss that are displayed in the marker
information are those of the current trace.
Differential Trace Analysis
The differential trace is the result of subtracting the values of the current trace from those of the
other trace.
• 4 Point Monitor
You can place cursors and 4 Point Monitor cursors on the current trace or differential trace and
monitor the following values.
• Loss (dB)
• Distance (km)
The differential trace cannot be saved.
