317User Manual 1178.3834.02 ─ 09
– If the volatile mode is disabled (default setting) the R&S SMA100B saves user
data permanently and only on this storage medium.
You can access data saved on the removable memory just as data saved in
the /var/user/.
– If the volatile mode is enabled, the R&S SMA100B redirects user data to the
volatile memory (SDRAM).
The volatile memory loses its contents when you power off the instrument.
●
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/.
See also Chapter 11.8.3, "How to display all saved files", on page 328.
For detailed information on how to protect the instrument and sensitive data from unau-
thorized access, see the Instrument Security Document on the product website.
11.4 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 SMA100B. In these
cases, you can save and recall instrument and user settings, and possibly other related
data.
Save/Recall the complete instrument settings
Two different methods are available for managing complete instrument settings:
●
Immediate (quick) Save/Recall
A defined set of instrument settings are saved or recalled quickly in just one step,
without defining a filename or storage location. This function enables a fast switch-
ing between different instrument settings.
●
Save/Recall in files with user-defined names
The defined set of instrument settings are saved to a definable storage location.
The file extension is *.savrcltxt.
Settings files created in this way are visible in the file system and accessible with
the supported methods for file handling.
In the general case, a recall process replaces the instruments settings with the saved
values. An exception is the frequency and level settings. During recall of the instrument
settings, it is possible to retain the current settings or to overwrite them with the saved
values.
