4. If you are in WDM mode, select whether the trace will be loaded as the
active trace or the reference trace.
You can select whether you want to also import the trace configuration
and overwrite the current analysis setup and acquisition context at the
same time that you open the file. The file type must be the same for the
configuration importation to be valid. If you have selected to open a
reference trace, the importation is done automatically.
Note: If you open an active trace and a reference trace is already present, the
current analysis setup will be applied to the active trace. If you open a
reference trace its analysis setup will replace the current analysis setup.
5. Press Open to open the file. The trace appears in the Graph tab. All the
values in the main window will also be updated from the file.
