Saving Traces
Saving Traces
After recalling, analyzing and displaying the two traces in the bidirectional
table, these traces may be stored as a merged bidirectional file in order to
facilitate file management. All information in the tables, comments and
reports for A->B, B->A, as well as the bidirectional trace will be saved in
the bidirectional file.
When you open a bidirectional file, you will recover all the data of the
bidirectional measurement, and the information of the unidirectional
traces. However, if you want to modify the unidirectional traces and
retrieve their complete data, you can export them from the bidirectional
file (see Exporting Unidirectional Traces from Bidirectional Files on
page 259). You will then be able to use them from the OTDR application.
By default, the suggested file name is based on the file name of the A->B
trace. If you prefer, you can modify the file name of the bidirectional file.
It is also possible to modify the path to the bidirectional file, but not the file
format (.bdr for the bidirectional file).
Note: The application will keep in memory the path that you use to save your
bidirectional measurement file. The next time you want to save a
bidirectional file, the application will suggest this path by default.
I
MPORTANT
The application saves the bidirectional file only. Consequently, the
changes you make to the unidirectional traces will not be saved to
the original files.
