How to Convert WFM Files

By Art Corvelay

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.

Things You'll Need

  • Windows
  • Tektronix Windows Oscilloscope WFM Converter

Download and install the Tektronix Windows Oscilloscope WFM Converter from the following URL: http://www2.tek.com/cmswpt/swdetails.lotr?ct=SW&cs=sut&ci=12389&lc=EN It is a free application that will allow you to convert .wfm files.

Step 2

Double-click the WFM converter .exe file and open up the command line in Windows.

Step 3

Select the .wfm file you would like to convert by entering the location and file name into the command line. For example, "ConvertTekWfm [ /c:/files | samplefile.wfm [ /TXT] [samplefile.txt]". The location for .wfm file c:/files and the file name is "samplefile.wfm".

Step 4

Select the output file type by entering the second argument in the command line. For example, "ConvertTekWfm [ /c:/files | samplefile.wfm [ /TXT] [samplefile.txt]". In this case, "[/TXT]" is the output file format.
