detect_model

RigolWFM.detect_model(filename: str) → str

Detect the oscilloscope model from a waveform file’s binary signature.

Reads a small prefix of the file and uses magic bytes, file size, and embedded model strings to identify the scope family.

Returns a short model string (e.g. "E", "Z", "5074") suitable for passing to Wfm.from_file().

Raises:

• FileNotFoundError – if the file cannot be opened.

• Parse_WFM_Error – if the signature is not recognised.
