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 saved and loaded later or
used in other instrument of the same kind.
See
Chapter 6.4, "Saving and Recalling Instrument Settings" , on page 81
●
SCPI scripts , a series of commands that can be run to perform a task.
See Chapter 6.5, "Exporting Remote Command Lists" , on page 85
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 AREG100A is switched off.
File storage location
Without any additional measures, the R&S AREG100A stores user files on the internal
memory or if connected, on a memory stick.
Both, the user directory
/var/user/
on the internal memory or the
/usb/
directory
on the memory stick, can be used to preserve user-defined data. Any directory struc-
ture can be created.
The
/var/volatile
directory serves as a RAM drive and can be used to protect
sensitive information. The data is available temporarily .
Default storage location
The R&S AREG100A stores user data in the user directory.
In the file system, user directory is always indicated as
/var/user/
.
In manual control, you access this directory via the "File Manager", see Chapter 6.6,
"Using the File Manager" , on page 86. In remote control, you can query it with the
command
:SYSTem:MMEMory:PATH:USER?
.
To query and change the default directory used for mass storage, use the command
:
MMEMory:CDIRectory
.
File handling
To access files and the file system of the instrument or to use the general file manage-
ment functions such as copying and moving data, use the standard "File Manager" dia-
log.
See Chapter 6.6, "Using the File Manager" , on page 86.
To transfer files from and to the instruments or to exchange files, use one of the follow-
ing alternatives:
●
Connect a memory stick to one of the USB interfaces.
