cleared. Thus, in secure user mode, the instrument always starts in a defined, fixed
state when switched on.
To store data such as measurement results permanently, it must be stored to an exter-
nal storage device, such as a memory stick.
Limited storage space
The volatile memory used to store data in secure user mode is restricted to 256
MB.
Thus, a "Memory full" error can occur although the hard disk indicates that storage
space is still available.
Storing required data permanently
Any data that is to be available for subsequent sessions with the R&S
FSV/A must be
stored on the instrument permanently,
before activating the secure user mode
. This
includes predefined instrument settings, transducer factors and self-alignment data.
Self-alignment data
Note that self-alignment data becomes invalid with time and due to temperature
changes. Therefore, to achieve optimal accuracy, it can be preferable to perform a new
self-alignment at the start of each new session on the R&S
FSV/A.
Restricted operation
Since permanent storage is not possible, the following functions are not available in
secure user mode:
●
Firmware update
●
Activating a new option key
Furthermore, since the "SecureUser" used in secure user mode does not have admin-
istrator rights,
administrative tasks
such as LAN configuration and some general
instrument settings are not available. Refer to the description of the basic instrument
setup ([SETUP] menu) to find out which functions are affected.
Activating and deactivating secure user mode
Only a user with administrator rights can activate (and deactivate) the secure user
mode. Once activated, a restart is required. The special user "SecureUser" is then log-
ged on to the R&S
FSV/A automatically using the auto-login function. While the secure
user mode is active, a message is displayed in the status bar at the bottom of the
screen.
