9.3 Protecting data
During operation, the R&S SMB100B saves user data permanently in the user direc-
tory, see "File storage location" on page 194.
To protect any classified data and to avoid saving any sensitive data on the
R&S SMB100B permanently, you have the following options:
●
Activate the volatile mode. This mode redirects user data to the volatile memory,
see "Volatile Mode" on page 252.
The internal memory is write-protected.
Once you power off the instrument for at least five minutes, all volatile memory
modules lose their contents.
Instead, you can redirect the user data to an external memory device, as, e.g., a
USB stick.

– "Default storage location" on page 194
– "Volatile Mode" on page 252
– Chapter 9.9.4, "Using a USB storage device for file transfer", on page 220
●
Save user files temporarily in the /var/volatile directory, which remains
available only until the instrument is turned off.
You can access data in the volatile memory just as data that is saved permanently
in the /var/user/.
See also Chapter 9.8.3, "How to display all saved files", on page 213.
For detailed information on how to protect the instrument and sensitive data from unau-
thorized access, see the Instrument Security Document on the product website.
