Revision 3.94.2

In $DATAFILES:

Copy the $DATAFILES folder from the DS to your local hard drive.

In order to open the files, you need to start MS Excel first and then open document. Then

choose "All files" in the document type.

Then go to the file path where you stored the $DATAFILES folder. Find the required

document named "project-name".csv. MS Excel will ask you if you want to use "Data using

column, tabulators etc.". Press "Next" and then "Complete".

The file will now open as a standard MS Excel file for you to review, print and analyze.

It is not possible to export this excel data back to the DS. That is covered in next section.

Also, in drive B are the system scope traces and the CSV/TSV formatted scope traces:
