OTDR 135
Measure Pane
Measure Pane
The application shows two, three or four markers: a, A, B, and b,
depending on the button you pressed under Measurements.
These markers can be repositioned along the trace to calculate loss,
attenuation, reflectance, and optical return loss (ORL).
You can reposition all markers by using the controls in the Markers section.
You can drag them directly from the trace display. Selecting marker A or B
will move the a-A or B-b pair.
For more information on how to perform manual measurements,
see Analyzing the Results Manually on page 185.
Trace Info Pane
The information about all the trace files (including the reference) can be
displayed.
You can view all of the traces, in turn, in both the Trace Info pane and the
trace display with the navigation buttons. For more information, see
Displaying or Hiding a Trace on page 147.
