Analyzing the Fiber on a Specific Fiber Span
Analyzing the Fiber on a Specific Fiber Span
If you want to focus your fiber analysis on a specific fiber span, you can
define events (new or existing) as a span start and/or span end. You can
even define a fiber span for short fibers by placing the span start and the
span end on the same event.
Note: You can set a default span start and end, which will be applied during the
first analysis or reanalysis performed upon trace acquisition.
To set a fiber span:
1. From the main window, go to the Events tab (for existing events) and
tap .
OR
From the main window, go to the Measure tab (for new events) and
tap .
2. For new events, define the span event location by moving marker A
along the trace using the left/right arrows. For more information see
Using Markers on page 83.
