Getting Event Distances and Relative Powers

Getting Event Distances and Relative Powers

The OTDR test application automatically calculates the position of an event
and displays this distance in the events table.

You can retrieve the position of an event as well as the distance between
events manually. You can also display various relative power readings.

Distances and relative powers correspond to the X-axis and Y-axis,
respectively.

To get the distance to an event and the associated relative power

level:
1.
From the main window, select the Graph tab and press the Measure

button.

2. Move marker A to the beginning of the event. For more information

about markers, see Using Markers on page 187.
