A [Preset] resets also external instruments connected to the R&S SMBV100B.
See Chapter 8.5.2, "External RF and I/Q Settings", on page 443.
9.3 Protecting Data
During operation, the R&S SMBV100B saves user data permanently in the user direc-
tory, see "File storage location" on page 472.
To protect any classified data and to avoid saving any sensitive data on the
R&S SMBV100B permanently, you can:
●
Install the option removable memory R&S SMBVB-B80
This option ensures that user data is never saved on the internal memory.
– Per default, if removable memory is mounted, user data is saved perma-
nently and only on this storage medium.
You can access data saved on the removable memory just as data stored in
the /var/user/.
– If volatile mode is activated or there is no memory mounted or it is removed
during operation, user data is stored temporarily in the volatile memory of
the instrument.
This data is lost once the instrument is switched off.
●
Store user files temporarily in the /var/volatile directory, which remains
available only until the instrument is switched off.
You can access data saved in volatile memory just as data stored permanently in
the /var/user/.
See also Chapter 9.8.3, "How to Display All Saved Files", on page 495.
●
Activate the volatile mode so that no user data can be written to the internal mem-
ory permanently.
The removable memory is protected, too.
Instead, you can only save user data:
– Temporary in the volatile memory
– On a connected external storage device, such as a memory stick

9.4 Saving and Recalling Instrument Settings
Possibly you would like to restore or repeat a signal generation you performed under
specific conditions on the instrument. Or, in a test setup with more than one signal gen-
erator, you want to transfer the used settings to another R&S SMBV100B. Some test
