Your application allows you to open WDM file type in spectral
transmittance mode.
While loading a WDM (.osawdm) file, the application behaves as if a new
acquisition is requested. This means that the application does not change
the modified state of the current measurement while loading a WDM file.
Before loading a WDM file, the application allows you to select in which
trace you want to import the WDM file. Select Input Trace, or Output
Trace as required. Once you have selected the file, the application imports
the following data in the selected trace.
