9.3 Protecting Data
During operation, the R&S
SMA100B saves user data permanently in the user direc-
tory, see
To protect any classified data and to avoid saving any sensitive data on the
R&S
SMA100B permanently
, you can:
●
Install the option
removable memory
R&S
SMAB-B85
This option ensures that user data is never saved on the internal memory.
–
Per default, if removable memory is
mounted
, user data is
saved perma-
nently and only on this storage medium
.
You can access data saved on the removable memory just as data stored in
the
/var/user/
.
–
If volatile mode is activated or there is
no memory mounted or it is removed
during operation, user data is stored
temporarily in the volatile memory
of
the instrument.
This data is lost once the instrument is switched off.
●
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/
.
Chapter 9.8.2, "How to Display All Saved Files"
●
Activate the
volatile mode
so that no user data can be written to the internal mem-
ory permanently.
The removable memory is protected, too.
Instead, you can only save user data:
–
Temporary in the volatile memory
–
On a connected external storage device, such as a memory stick
