4.7 File Management
The R&S SMU uses files to save all instrument data, i.e. system and user data.
The user data includes saved instrument settings, data for the different digital standards,
lists for the List mode and the user correction as well as the waveforms for the arbitrary
waveform generator.
The files are stored on the hard disk of the instrument. Drive D:\ can be used to save
user-defined data; any directory structure can be created on D:\. Some default directo-
ries are predefined, but can be changed at any time.
The C:\ drive is a protected system drive. The files on this drive 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 specified in the file menus. It can be accessed if a protection
level (see section "Protection Level" in the Operating Manual) is revoked.
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 E: 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.
For example, files with frame settings can only be saved and loaded in the "GSM/
EDGE" menu. See chapter 4.7.2.1, "Extensions for User FilesExtensions for User
Files", on page 117 for an overview of the supported file extensions.
The user data can be roughly divided into four data types:

Settings, e.g. the frame setting of the GSM/EDGE standard, can be loaded and cur-
rent setting saved to the specified file.
