The "Disk & Memory" tab secures controlled access to the mass memory and pre-
vents information from leaving a secure environment.
The remote commands available to control security settings are described in Chap-
ter 13.17, "SYSTem Subsystem", on page 653.
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 10.9.4, "Using a USB Storage Device for File Transfer",
on page 310.
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 10.3, "Protecting Data",
on page 290.
●
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 662
Sanitize
Executes the erase procedure that sanitizes the internal memory.
