What is a .WFM file?
WFM is a captured waveform from a digital oscilloscope.
- Did you know
- A WFM saves the exact trace an oscilloscope measured for later study.
- A WFM is a closed, vendor-specific binary format, so a Tektronix file and a Rigol file of the same name are not interchangeable.
- It is designed to be written and read quickly by the scope itself, storing the raw sample values plus capture settings.
- What Analyser reads
- Identify and read more scientific, medical and engineering files: R serialized data (RDS/RData), ABIF sequencing traces, VASP/Gaussian/XCrySDen DFT structures, ChemDraw (CDX/CDXML), Axon ABF and NI TDMS instrument data, BrainVision/Neuroscan/EEGLAB EEG, Gmsh/Abaqus/Nastran/ANSYS FEA decks, SPICE netlists, VTK structured/rectilinear grids and oscilloscope waveforms.
- Depth of analysis
- .WFM is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .WFM file
- Drag a .WFM file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
