Secure User Mode
(R&S
FSV3-K33, Security Write Protection)
If users must not obtain knowledge of other user's data, the optional secure user mode
is available. If enabled, the SSD is write-protected so that no information can be written
to its memory permanently. Data that the R&S
FSV/A normally saves on the SSD is
redirected to volatile memory instead, which is not a security concern.
Data that is saved in volatile memory can be accessed just as in normal operation.
When the instrument’s power is removed, all data in this memory is cleared. Thus, in
secure user mode, the R&S
FSV/A always starts in a defined, fixed state when turned
on.

Special Considerations for USB Ports
USB ports can pose a security risk in high-security locations. Generally, this risk comes
from small USB pen drives, also known as memory sticks or key drives. They can be
easily concealed and can quickly read/write several Gbyte of data.
Disabling USB ports for writing user data
You can disable the write capability on the USB ports of the R&S
FSV/A with a soft-
ware utility.
If your R&S
FSV/A is equipped with option R&S
FSV3-B33 (USB mass memory write
protection), the software utility is already installed on the instrument.
Without option R&S
FSV3-B33, Rohde
&
Schwarz provides the software utility on the
R&S
FSV/A website attached to this document, see (
https://www.rohde-schwarz.com/
and
www.rohde-schwarz.com/manual/fsva3000.html
).
Proceed as follows:
1. Download the software utility.
2. Copy the software utility to the R&S
FSV/A.
3. Run it once.
After a reboot of the instrument, the write capability on any USB memory device is dis-
abled.
