5.2.8 Storing and Loading Instrument Data - File Key

The R&S SMB allows complete instrument settings to be stored in files either on the
internal flash memory or on external USB memory devices.
Defined and complex instrument settings can then be reproduced at any time by load-
ing this data. If required, these settings can be loaded to various signal generators.
The corresponding menu is available under "Save/Recall" in the "Setup" menu. The
instrument settings are saved in files which can be stored in data directories.
Additionally there are intermediate memories in which the current instrument setting
can be stored and then called up again by just pressing a key. This provides fast
switching between different instrument settings.
Only settings which differ from the preset values and configuration data for the operat-
ing elements (e.g. window positions) are stored. As a result the files remain relatively
small. Furthermore, instrument settings can easily be transferred between different
equipped signal generators since the files contain only relevant information. When loa-
ded, the referenced settings are implemented and all non-referenced parameters are
set to the associated preset values.
If list data is part of the instrument settings, e.g. a list of user correction data, a refer-
ence to this list is stored, not the list itself. The list is reactivated when the associated
settings are loaded, but the list may have been modified or deleted in the meantime or
may not be available on a different instrument. If the list has been modified, the new
entries will be used. An error message appears if an attempt is made to access a non-
existing list or to activate settings which are not supported by the instrument.
●
Network settings and remote settings are not saved and restored.
●
Lists are stored and loaded in the appropriate menus. For example, the user cor-
rection data list is created and stored in the "User Correction" menu.
When loading an instrument setting, it is possible to select whether the current fre-
quency and level setting is to be retained or whether the stored settings are to be acti-
vated. It is possible to delete stored instrument settings. A file can be copied by loading
it with "Recall" and then storing it under a new name.
Settings can be transferred easily between instruments with different equipment
options and/or firmware versions because only the settings which differ from the preset
values are affected. When settings are loaded, only those which are possible on the
instrument are implemented. Error messages indicate the settings which cannot be
implemented.
The stored file is transferred from one instrument to another using the memory stick.
