4.7 File Management
The R&S SMB uses files to save all instrument data, i.e. system and user data.
The user data includes saved instrument settings and lists and the user correction.
The files are stored in the internal memory of the instrument or on a USB memory 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 system drive and therefore unaccessible system direc-
tory. The files on this directory contain data that must not be changed. Therefore, this
drive 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 drive is not speci-
fied in the file menus.
Files can be exchanged either via a memory stick or a connected network. A memory
stick is connected to the USB interface and is assigned the var/usb/ drive. In the case
of a connected network, all network drives that can be accessed are available. The files
are accessed in a "Save/Recall" dialog in the individual menus.
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.
See chapter 4.7.2.1, "Extensions for User Files", on page 74 for an overview of the
supported file extensions.
The user data can be roughly divided into the following data types:
●
Settings
Instrument settings can be saved and loaded. In case of saveing, the current setting
is saved to the specified file.
●
Lists
