Tektronix is a company that produces oscilloscopes. These machines produce files in a proprietary file format known as .wfm. These .wfm files cannot be opened by more common computer applications. However, you can convert .wfm files into a few other file types including text files (.txt), comma-separated files (.csv), MATCAB and MATLAB files. These output file types are much more commonly used than the .wfm file format.
