8.7 Configuration preset

The configuration preset excludes measurement range, value and bias settings.

Indication and selection of a configuration presets
One of the three presets is always active, while the other two are inactive, as
shown on the screen:
– Indication
The
(configuration preset) indicator displays the currently active configu-
ration preset.
The different colors of each preset emphasize the display.
– Selection
The
(preset configuration) softkeys on the screen enable you to activate a
preset directly.
The R&S LCX provides always the two selectable, i.e. the currently inactive
preset softkeys. When you switch to another configuration preset, it adjusts the
labels of the keys and the indicator according to the selection.
When switching to another preset or changing setting parameters, consider
that it can last up to 10 seconds to be sure that all settings are saved.
●
Persistency of configuration presets
The R&S LCX saves a configuration in the selected, i.e. active configuration pre-
set. It saves the settings on the internal file system, which is not accessible. After
power off, the instrument reboots with the recently active configuration preset.
●
Saving options
The settings of the active configuration preset are also included in the "Save/
Recall" function and saved in the *.rds file. When you recall a settings file, the
R&S LCX restores the configuration preset from the file to the same memory slot
("Preset 1, 2 or 3") it was created on. It is not possible to assign it to another slot.
