If the default values in the "Remote Access" dialog had been changed, a factory preset
via remote control (:SYSTem:FPReset) terminates the connection to the instrument.
Security settings are never reset.
Resets all parameters and switching states, and closes all opened dialogs.
A [PRESET] resets also external instruments connected to the R&S SMW.
See Chapter 4.4.3, "External RF and I/Q Settings", on page 135.
11.3 Protecting Data
During operation, the R&S SMW saves user data permanently in the user directory,
see "File storage location" on page 671.
To protect any classified data and to avoid saving any sensitive data on the
R&S SMW permanently, you have the following options:
●
Activate the volatile mode. This mode redirects user data to the volatile memory.
The internal memory is write-protected.
Instead, you can redirect the user data to an external storage medium, as, e.g., a
USB stick.

– "Default storage location" on page 671
– "Volatile Mode" on page 757
– Chapter 11.9.4, "Using a USB Storage Device for File Transfer", on page 701
●
Save user files temporarily in the /var/volatile directory, which remains
available only until the instrument is turned off.
You can access data in the volatile memory just as data that is saved permanently
in the /var/user/.
