Internal Format Waveform Files (.wfmx)

The internal-format waveform files XML file (.wfmx) are comprised of an ASCII XML header followed by binary waveform data. The file includes vertical and horizontal scaling parameters of the waveform. Therefore, when you load the waveform into a waveform memory, you can still perform automatic measurements and use markers on that waveform. The internal format is binary, so you can not directly display the file contents in a word processing or spreadsheet program. However, you can convert an internal format file to a text file (.txt) for use in a spreadsheet or word processing program, by loading the file into waveform memory and then re-saving the waveform in either Y-values format or XY-values format.
