The PRESET key calls up a defined instrument setup. All parameters and switching
states are preset (also those of inactive operating modes). The default instrument
settings provide a reproducible initial basis for all other settings. However, functions
that concern the integration of the instrument into a measurement setup are not
changed, e.g. IEC/IEEE bus address or reference oscillator source settings.
In remote control it is possible to preset the settings of the two instrument's paths
separately (see section "Preset Commands").
●
Preset the instrument to its factory settings
The instrument can also be forced to load its default factory settings. To access the
corresponding dialog box, press the SETUP key and select the "Factory Preset".
For more information and an overview of the settings affected by the factory preset
function, see chapter 5.2.3.18, "Factory Preset", on page 148.
