Types of user data
Depending on the
content
, the
user data
can be roughly divided into the following
data types:
●
Settings
, e.g. the current instrument settings, can be stored and loaded later or
used in other instrument of the same kind.
See
Chapter 9.4, "Saving and Recalling Instrument Settings"
●
SCPI scripts
, a series of commands that can be run to perform a task.
Chapter 9.6, "Exporting Remote Command Lists"
●
Externally or internally generated
lists
, e.g. user correction lists, or data lists can be
loaded in the instrument.
See
Chapter 9.7, "Loading, Importing and Exporting Lists"
Chapter 9.5, "Accessing Files with User Data"
Depending on the
data storage method
, user data can be:
●
Persistent
, i.e. user files that are recorded on the data storage.
Data is preserved when instrument is powered off and can be accessed and modi-
fied subsequently.
●
Temporary
, i.e. volatile data that the instrument retains while it is powered on.
Volatile data is immediately lost when the R&S
SMA100B is switched off.
File storage location
Without any additional measures, the R&S
SMA100B stores user files on the internal
memory, or if selected, on a memory stick.
Both, the user directory
/var/user
on the internal memory or the
/var/usb
direc-
tory, can be used to
preserve
user-defined data. Any directory structure can be cre-
ated.
The
/var/volatile
directory serves as a RAM drive and can be used to protect
sensitive information. The data is available
temporarily
.
If option R&S
SMAB-B85 is installed, the R&S
SMA100B maps the user directory to
the removable memory. If a memory is mounted, user data is saved there. Otherwise
user data is redirected to the volatile memory.
Default storage location
The R&S
SMA100B stores user data in the user directory.
Depending on the installed options, the user directory is physically located on the inter-
nal memory or on the
.
In the file system, user directory is always indicated as
/var/user
.
In manual control, you access this directory via the "File Manager", see
on page 204. In remote control, you can query it with the

To query and change the default directory used for mass storage, use the command
