When you push File Details on the side menu, the oscilloscope changes the side menu contents.
The following table describes these side m enu items for saving data to a mass storage file.
side menu button Description
Internal File Format (.ISF) 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 t
he fastest to w rite 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.
Spreadsheet file format
(.csv)
Sets the oscilloscope to save waveform data as a comma-separated data file compatible with
popular
spreadsheet programs. This file can also be recalled to reference memory.
Saving an analog waveform to reference memory. To save an analog waveform to nonvolatile memory inside
the oscilloscope, push the Save Waveform screen button, select the waveform that you want to save, and then select
one of the four reference waveform locations.
Saved waveforms contain only the most recent acquisi tion. Gray-scale information, if any, is not saved.
NOTE. 5M, 10 M and 20 M reference waveforms are volatile and not saved when the oscilloscope power is turned off. To
keep these waveforms, save them to external storage.
