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 11.3, "Protecting Data",
on page 679.
●
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 the icon
.
Remote command:
:SYSTem:SECurity:VOLMode[:STATe] on page 1226
Sanitize
Executes the erase procedure that sanitizes the internal memory.
The sanitizing 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.
Note: If the instrument is subject to high security, and you have disabled volatile mode,
the internal memory holds user-data, and thus poses a security risk.
See also Chapter 12.6, "Using the Security Settings", on page 752 for more informa-
tion on the security concept.
Remote command:
:SYSTem:SECurity:SANitize[:STATe] on page 1235
