About waveform data files
.ISF ( Internal File Format) : Sets the oscilloscope to save waveform data from analog channels (and math and reference
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.
.CSV (comma separated values): Sets the oscilloscope to save waveform data as a comma-separated data file
compatible with popular spreadsheet programs. This file cannot be recalled to reference memory. A CSV file is
significantly larger than an ISF file, and takes longer to write to the USB drive.
To find out the channel for which the file was written, open the file in a text editor. The channel name is in the top
few lines of the file.
