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 209. 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.
12.5.1 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.
File extension
The file and the optional file extension are separated by a period sign. The
R&S SMB100B distinguishes the files according to their extensions; each type of file is
assigned a specific file content and hence a specific file extension. Refer to Chap-
ter A.2, "Extensions for user files", on page 606 for an overview of the supported file
extensions.
Wildcards
The two characters "*" and "?" function as "wildcards", i.e. they are used for selecting
several files. The "?" character represents exactly one character, while the "*" charac-
ter represents all characters up to the end of the filename. "*.*" therefore represents all
files in a directory.
Filename and file path
When used in remote control commands, the parameter <filename> is specified as a
string parameter with quotation marks. It can contain either the complete path including
the root user directory /var/user and filename, or only the filename. The filename
must include the file extension. The same applies for the directory /var/volatile
and for the parameters <directory_name> and <path>.
Depending on how much information is provided, the values specified in the parameter
or with the command MMEM:CDIR are used for the path and drive setting in the com-
mands.
