File extension
The file and the optional file
extension
are separated by a period sign. The
R&S
SMBV100B 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
ter A.3, "Extensions for User Files"
on page 979 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.
12.6.2
Accessing Files in the Default or in a Specified Directory
For better overview and easy file handling, you may not save all user files in the user
directory
/var/user
but rater organize them into subdirectories.
The command syntax defines two general ways to access files with user data in a
spe-
cific
directory:
●
Change the current default directory
for mass memory storage and then directly
access the files in this default directory, like stored list files, files with user data or
save/recall files.
(See
Example "Store the user settings in a file in a specific directory"
on page 619).
The subsequent commands for file handling (select, delete, read out files in the
directory, etc.) require only specification of the filename. File extension can be
omitted; after syntax evaluation of the used command, the R&S
SMBV100B filters
out the relevant files.
●
Define the
absolute file path
, including the user directory
/var/user
, created
subdirectories and filename (see
Example "Load file with user data from a specific
As a rule, whenever an absolute file path is determined, it overwrites a previously
specified default directory.
The following example explains this rule as a principle. Exceptions of this general rule
are stated in the description of the corresponding command. The
