Description
Internal File Format (.ISF) Sets the oscilloscope to save waveform data from analog channels (and math and re ference
waveforms derived from analog channels), in internal waveform save file (.isf) format. This format
is the fastest to write and creates the smallest-sized file. Use this format if you intend to recall a
waveform to reference memory for viewing or measuring.
The oscilloscope cannot save digital waveforms in an .isf file format.
