From the Measure tab, tap.

The application will use a file name based on the autonaming parameters you defined see Naming Trace Files Automatically on page manua, EXFO also warrants that this equipment will meet applicable specifications under normal use. Markers a, A, B and b appear on the graph. Page 39 Preparing Your OTDR for a Test Setting the Analysis Detection Thresholds The following examples show how otsr splice-loss threshold levels can affect the number of displayed events, especially small non-reflective events such as those caused by two splices.

The application automatically adjusts the zoom by a factor 2 around the point that was tapped. Analyzing Traces and Events Managing Comments 4. If you want to use the data or to customize your report later with your own exco, select XML.

The value found by an auto acquisition cannot be modified. At the bottom of the window, tap Event. For more information, see Analyzing Traces and Events on page A-B LSA loss is mainly used to rapidly compute loss over a given length of a fiber section. For each item listed in the events table, information is displayed: By default, this feature is disabled. Enter the desired information.

The information you enter is saved for the currently open trace file or the next dxfo depending on your choice.
