12.6 MMEMory Subsystem
The MMEMory subsystem (Mass MEMory) contains the commands for managing files
and directories as well as for loading and storing complete instrument settings in files.
Mass storage location
Without any additional measures, the R&S SMBV100B stores user files on the internal
memory, the removable 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.
If option R&S SMBVB-B80 is installed, the R&S SMBV100B 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 SMBV100B 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 removable memory.
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 9.8,
"Using the File Manager", on page 491. 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.
12.6.1 File Naming Conventions
To enable files to be used in different file systems, consider the following file naming
conventions:
●
The filename can be of any length and is case-sensitive, i.e it is distinguished
between uppercase and lowercase letters.
●
All letters and numbers are permitted (numbers are, however, not permitted at the
beginning of the filename).
●
Avoid using special characters.
●
Do not use slashes "\" and "/". These symbols are used in file paths.
●
Avoid using the following filenames: CLOCK$, CON, COM1 to COM4,
LPT1 to LPT3, NUL or PRN
They are reserved by the operating system.
