4.7 File Management
The R&S SMJ 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 stand-
ards, 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 direc-
tories 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. See
Chapter 4.7.2.1, "Extensions for User Files" , on page 118 for an over-
view of the supported file extensions.
The user data can be roughly divided into the following data types:
●
Settings
Settings, e.g. the frame setting of the GSM/EDGE standard, can be loaded and
current setting saved to the specified file.
●
Lists
Lists, e.g. user correction lists, can be loaded. They can be generated either exter-
nally or internally. For internal generation, a new list must be created in the "File
Select" dialog which will then be edited in the list editor of the individual menu.
●
Complex modulation and control data
User data of this type can be loaded. It can be generated either externally or inter-
nally. For internal generation, a new list must be created which will then be edited
