mode the instrument’s solid-state drive is write-protected so that no information
can be written to memory permanently. Data that the R&S FSV/A normally stores
on the solid-state drive is redirected to volatile memory instead, which remains
available only until the instrument is switched off. This data includes:
●
Windows operating system files
●
Firmware shutdown files containing information on last instrument state
●
Self-alignment data
●
General instrument settings such as the IP address
●
Measurement settings
●
User data created during operation
●
Any data created by other applications installed on the R&S FSV/A, for exam-
ple text editors (Notepad), the Clipboard, drawing tools, etc.
Users can access data that is stored in volatile memory just as in normal opera-
tion. However, when the instrument’s power is switched off, all data in this mem-
ory is 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
external 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 indi-
cates 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 temper-
ature changes. Therefore, to achieve optimal accuracy, it may be preferable
to perform a new self-alignment at the start of each new session on the
R&S FSV/A.
