NOTE
Acquisitions must be done with the same resolution. If not, the addition of
markers cannot be performed perfectly.
Test of a cable
In order to test a full cable, it is first necessary to make an OEO reference trace, where
all fiber events have been marked on both origin and end traces.
This trace may be obtained by requesting an auto-measurement after which markers
may be added, or by performing a manual measurement.
The next step consists in memorizing all markers, by selecting
page.
NOTE
If the auto mode was set for the referencing, it is recommended to change to
manual mode for the next fibers. This will ensure that setup parameters used
for all the fibers will be the same than those used for the reference trace.
