Save and Recall Information
5. Push File Details to save to a USB or
network drive.
File Details
This brings up the fi le manager screen. Use
it to navigate to the desired drive and folder,
and optionally to specify the
fi le name.
Skip this step to use the default name and
location.
Saving a waveform to fi le.
When you push the File Details side-bezel menu button, the oscilloscope changes the side-bezel
menu contents. The following table describes these side-bezel menu items for saving data to a mass storage fi le.
Side-bezel menu button Description
Instrument Speci fi c File
Format (.ISF)
Sets the oscilloscope to save data from analog, digital, or RF channels (and math and
reference waveforms derived, where possible, from those channels), in Instrument Speci
fi c
Format (.isf) format. This format is the fastest to write. It also creates the smallest-sized fi le.
Use this format if you intend to recall an analog waveform or RF trace to reference memory
for viewing or measuring.
Spreadsheet fi le format
(.csv)
Sets the oscilloscope to save data as a comma-separated data fi le that is compatible with
popular spreadsheet programs.
Analog and RF data stored in this
fi le format can also be recalled to reference memory.
Saving a waveform or trace to reference memory.
To save a waveform or trace 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 acquisition. Gray-scale information, if any, is not saved.
NOTE. 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.
Displaying a reference waveform.
To display a waveform stored in nonvolatile memory:
1. Push Ref R .
