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.
