11.2.3 How to recall user settings automatically after preset
You can define the settings that are restored when you preset the instrument.
1. Configure the settings as required. Save them as described in Chapter 11.4.2,
"How to save and recall instrument settings", on page 320.
2. Save the settings as a file with the predefined filename UserPreset.savrcltxt.
Save this file in the directory /var/user/.
The filename UserPreset.savrcltxt and the directory /var/user/ are man-
datory.
Now when you press the [Preset] key or send the *RST command to the instru-
ment, the defined settings are restored.
An "Info" message appears and confirms, that a file with user-defined preset set-
ting is loaded.
11.2.4 Reference
See Table 11-1 for an overview of the main generator settings that are affected by the
corresponding preset functions. While the regular [Preset] key primarily resets the sig-
nal relevant parameters of the instrument, the "Factory Preset" affects almost all instru-
ment settings.
For information on the default values of further parameters, refer to the description of
the corresponding remote commands.
