letter assignment
If Windows operating system is installed, the Windows
operating system assigns the first available drive letter
(typically E:) to the first USB device attached to the
oscilloscope, regardless of which port the USB device is
plugged into. The next plugged-in USB device is assigned
the next available drive letter (such as F:) and so on for
other installed devices.
Use standard Windows procedures to mount and access
network drives.
Save As configuration menu (File menu)
Use this menu to configure saving screen captures, waveforms, oscilloscope setups, reports, and session files.
To access the Save As configuration menu, tap File on the menu bar and select Save As....
NOTE. Selecting File > Save the first time after powering up the oscilloscope opens the Save As configuration menu. This lets
you set or verify the save locations for all types of information you can save.
Once the Save As configuration menu has been opened and closed, the next time you select Save causes the instrument to
automatically save the file type last selected in the Save As configuration menu. This lets you quickly save files with a simple
menu selection.
