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.
