File Management
The R&S SMC uses files to save all instrument data, i.e. system and user data. The user data includes
saved instrument settings and lists for the user correction.
The files are stored in the internal memory of the instrument or on a USB memeory stick. The /var
directory can be used to save user-defined data; any subdirectory structure can be created on /var.
Some default subdirectories are predefined, but can be changed at any time.
The /opt directory is a protected and therefore unaccessable system directory. The files on this directory
contain data that must not be changed. Therefore, this directory should not be accessed, since
reconstruction of the system partition will lead to data loss. To prevent inadvertent deletion or
overwriting of system files, this directory is not specified in the file menus.
Files can be exchanged via a memory stick. The memory stick has to be connected to the USB
interface and accessed via the File menu.
The files are accessed in a File Select window in the individual menus. Depending on the data type, a
file can either be selected or it can be selected and saved:
• Instrument settings can be saved and loaded. In case of saving, the current setting is saved to the
specified file.
• Lists, e.g. user correction lists, can be loaded. They can be generated either externally or internally.
For internal generation, a new list must be created in the File Select window which will then be
edited in the list editor of the individual menu.
The files are differentiated according to their extensions; each type of file is assigned a specific file
content. The extension is usually of no consequence to the user since access to the files occurs in
the individual menus where only the relevant type of file is available.
A button in the individual menu calls up the selection of the Select/New and File Manager functions.
After the Select/New selection, a File Select window for loading, saving or creating a file is displayed
(see the following section "File Select Menu", page 3.23).
After the File Manager selection, a menu for managing all files is displayed (see section "File
Manager", page 3.24).
The complete instrument settings are saved and loaded in the File menu which is called up by means
of the
File key (see chapter 4, section "Storing and Loading Instrument Data").
