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.
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
tion.
