USB Storage
Activates the access to external USB storage media.
To apply the change: enter the security password and confirm with "Accept". Otherwise
the change has no effect.
See also Chapter 9.9.4, "Using a USB Storage Device for File Transfer" , on page 502.
Volatile Mode
Activates volatile mode, so that no user data can be written on the internal memory
permanently.
In volatile mode:
●
Data that the instrument normally stores on the internal memory is redirected to
volatile memory.
●
The user directory is mapped to the volatile memory. You access the temporary
data just as data stored in the
/var/user/
, see Chapter 9.3, "Protecting Data" ,
on page 480.
●
Data on the internal memory cannot be changed. It is protected against modifica-
tion or erasure.
●
You can only save data:
–
Temporarily in the volatile memory
– On a connected external storage device, such as a memory stick
To activate volatile mode: enter the security password, confirm with "Accept" and
reboot the instrument. Otherwise the change has no effect.
Activated volatile mode is indicated by an icon.
Remote command:
:SYSTem:SECurity:VOLMode[:STATe]
on page 897
Sanitize
Executes the erase procedure that sanitizes the internal memory.
If the instrument is subject to high security, and you have not enabled the volatile
mode, the internal flash memory holds user-data, i.e. id poses a security risk. The sani-
tizing function makes sure that no user information is stored on the instrument when it
leaves the secure environment.
To apply the change: enter the security password and confirm with "Accept". Otherwise
the change has no effect.
See also Chapter 10.5, "Using the Security Settings" , on page 535 for more informa-
tion on the security concept.
Remote command:
:SYSTem:SECurity:SANitize[:STATe]
