Save/Recall User - Digital Modulation
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.
