457User Manual 1178.3834.02 ─ 09
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 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 11.8,
"Using the file manager", on page 324. 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.
14.5.1 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 SMA100B 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 Chapter B,
"Extensions for user files", on page 781 for an overview of the supported file exten-
sions.
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.
