The Tektronix wfm file format saves and restores waveform data for internal use. It is based on the SCPI Data Interchange Format standard. Waveforms have X or Y dimension data and Curve data. Acquired waveform curve data is in integer format. It includes extra points not seen on screen for display interpolation. There are 16 PreCharge and 16 PostCharge data points.
Tektronix defined the wfm format. Software supporting it includes WaveStar for Windows devices. The WaveStar program was created by Tektronix. More details on software and wfm files are on their website. Programs supporting wfm files are WaveStar and Tektronix Windows Oscilloscope WFM Converter.
For example, wfm files are sometimes converted to CSV or text files. Then they are imported into analysis software like MATLAB. below is a list of software opening Tektronix Waveform Data Files on Windows:
– Tektronix WaveStar
– Tektronix Windows Oscilloscope WFM Converter
WFM files contain oscilloscope data from Tektronix. WaveStar opens them, and the Converter exports them. To open a wfm file, use suitable software like Tektronix. Without it, Windows gives “How do you want to open this file?” or “Windows cannot open this file” messages. If you cannot open a wfm file correctly, right-click or long-press it.
We also have free online wfm file tools. They allow viewing, editing, converting, merging, splitting, and comparing wfm files without installing anything. Please click the links to see details for each feature.
The wfm file extension relates to Tektronix Digital Phosphor Oscilloscopes. They use a new compressed wfm format for faster saving and loading of waveform data. The format has more information than older ASCII files. The default software to open wfm files is Tektronix Microsoft Windows software.
The WFM data file works with Tektronix Waveform Converter. The Tektronix site has more information on the wfm format and Converter. WFM files store Tektronix Oscilloscope Waveform Data designed for internal use. The format is based on the SCPI standard.
