10.3 Protecting Data
During operation, the R&S SMW saves user data permanently in the user directory,
see "File storage location" on page 620.
To protect any classified data and to avoid saving any sensitive data on the
R&S SMW permanently, you can:
●
Store user files temporarily in the /var/volatile directory, which remains
available only until the instrument is switched off.
You can access data saved in volatile memory just as data stored permanently in
the /var/user/.
See also Chapter 10.8.3, "How to Display All Saved Files", on page 642.
●
Activate the volatile mode so that no user data can be written to the internal mem-
ory permanently.
Instead, you can only save user data:
– Temporary in the volatile memory
– On a connected external storage device, such as a memory stick
