Save/Recall User
Calls the "Save/Recall User" menu.
From the "Save/Recall User Standard" menu the "File Select" windows for saving and
recalling user-defined standards and the "File Manager" can be called.
User standards are stored as files with the predefined file extension
*.dm_stu
. The
file name and the directory they are stored in are user-definable.

Symbol Rate
Selects the symbol rate.
The value range is dependent on the selected modulation type.
When the modulation type changes, the range is automatically redefined. If the set
symbol rate is outside this range, an error message is generated and the maximum
value for the newly chosen modulation type is automatically set.
Remote command:
[:SOURce<hw>]:BB:DM:SRATe

Coding
Selects the coding (see Chapter 5.8.2.3, "Coding - Custom Digital Mod" , on page 330).
The menu offers only the coding settings that are permissible for the chosen modula-
tion type. The other coding methods are grayed out.
If the system is subsequently switched to a modulation type for which the selected cod-
ing is not available, coding is automatically set to OFF.
