wdf_to_wvf

RigolWFM.yokogawa_wdf.wdf_to_wvf(wdf_path: str, output_dir: str | None = None, block_index: int | None = None) → tuple[str, str][source]

Convert a Yokogawa DL850 .WDF file to a .hdr + .wvf pair.

Parameters:

  • wdf_path – Path to the input .WDF file.

  • output_dir – Directory for the output files. Defaults to the same directory as the input file.

  • block_index – When given, export only this single history block (0-origin, where 0 = earliest capture). By default all history blocks are exported.

Returns:

(hdr_path, wvf_path) — paths to the two output files.

Raises:

NotImplementedError – Always. The WDF binary format is not publicly documented and cannot be parsed without DL850.dll (a Windows-only, non-redistributable library).
