What file formats do oscilloscopes export?
The scopes I've worked with could save screenshots as bitmaps (BMP or PNG), and a few formats of numerical data, among which there was always CSV (Comma-Separated Values), which can be used to import in MatLab, Excel, or any program you write that can handle text files (Edlin anyone? :-)).
Other formats are mostly proprietary, I don't think there's a universal XML format for scope data as yet.
