1.4 Analyzing Measured Data (OTDR)
Marker Analysis (TRACE mode)
You can manually use cursors and markers to measure values such as the distance, splice loss, and
return loss between two points.
Distance between Two Points
The distance from the start point to the cursor position is displayed.

Splice Loss
When you place four markers as shown in the following figure, the splice loss from the measurement
start position to the measurement end position is calculated, and the value is displayed.

Note
In addition to the above method, the splice loss can be measured by using six markers or by using line
markers. For details, see section 6.1.
