5.2 General Instrument Settings
5.2.1 Overview of General Instrument Settings
This section describes the settings which do not directly affect signal generation. Most
of these settings can only be accessed by means of menus which are opened using
keys or key combinations on the external keyboard or keys on the front panel key emu-
lation.
This does not apply to the graphical representation of output signals which is activated
in the "Graphics" function block, or settings which can additionally be called up in the
menus of the function blocks, e.g. input configuration which is possible in the "Setup"
menu and in almost every menu of the "Baseband" function block.
See also Chapter 4.8, "Legend of Front-Panel Controls" , on page 120.
The general instrument settings therefore affect various functions, such as storing
instrument settings using the FILE key or setting the GPIB address in the menu of the
SETUP key. The order in which the descriptions are given corresponds to the layout of
the keys on the front panel of the R&S
SMJ (from top left to bottom right).
5.2.2 Default Instrument Settings - Preset Key
The PRESET key performs a defined instrument setup. All parameters and switching
states are preset (also those of inactive operating modes). The default instrument set-
tings provide a reproducible initial basis for further settings.
However, functions concerning the integration of the instrument in a measurement
setup are not changed, for example the GPIB address or reference oscillator settings.
In addition, only those settings associated with the menu can be reset directly in the
individual dialogs, like the digital modulation settings in the "Custom Digital Mod"
menu. These settings are identical with the values set with the PRESET key.
When the instrument is switched on, it is not the preset state that is active, but rather
the instrument state that was set before the instrument was switched on.
User-defined instrument states can be accessed and stored in the "File" menu.
Resetting the instrument to the factory state is possible with the Factory Preset func-
tion.

Presets all parameters and switching states.
The following list gives an overview of the presets for the most important generator set-
tings. The other presets can be found in the preset tables of the individual menus and
the information accompanying the remote commands.
