Selecting the Default File Format
3. In the Browse for Folder window, select the location where you want
to save the file.
Note: If you want to create a folder, you will have to do it manually via File
Manager available from the Home screen.
4. Tap OK to exit the Browse for Folder window.
5. Tap OK to return to the main window.
Selecting the Default File Format
You can define the default file format the application will use when you
save your traces.
By default, traces are saved in native (.trc) format, but you can configure
your unit to save them in Bellcore (.sor) format.
If you select the Bellcore (.sor) format, the unit will create one file per
wavelength (for example, TRACE001_1310.sor and TRACE001_1550.sor, if
you included both 1310 nm and 1550 nm in your test). The native format
contains all wavelengths in a single file.
Note: If you selected the feature to be prompted each time you save a
measurement, you can also modify the file format temporarily. Next time
you save a measurement, the default file format will be used.
Note: The Save As button allows you to save your files to a folder different from
that of the default file format. If you change the file format from the Save As
dialog box, it will be used the next time you use the Save As feature again.
The default file format will not be modified.
