List Management - Digital Modulation
Calls the menu for managing data and control lists (see ​"List Management"
on page 73).
Remote command:
n.a.
Standard, Symbol Rate, Coding
The middle part of the menu is used for selecting the standard, the symbol rate and the
coding.
Set acc. to Standard - Digital Modulation
Selects a standard.
After selection, modulation parameters "Modulation Type", "Symbol Rate", "Filter" and
"Coding" are automatically set in accordance with the standard.
If one of these parameters is subsequently altered, the display changes to User. The User
setting can be saved to a file so that it can be recalled at some later time ("Save/Recall
User.." button).
The following table shows the standards that are available, together with the associated
settings of the modulation parameters.
