Baseband Block<br />

Symbol Rate - Digital Modulation<br />

Selects the symbol rate.<br />

The value range is dependent on the selected modulation type.<br />

When the modulation type changes, the range is automatically redefined. If the set symbol<br />

rate is outside this range, an error message is generated and the maximum value for<br />

the newly chosen modulation type is automatically set.<br />

Remote command:<br />

​[:​SOURce]:​BB:​DM:​SRATe​ on page 235<br />

Coding - Digital Modulation<br />

Selects the coding (see ​chapter 5.10.2.2, "Coding - Custom Digital Mod", on page 55).<br />

The menu offers only the coding settings that are permissible for the chosen modulation<br />

type. The other coding methods are grayed out.<br />

If the system is subsequently switched to a modulation type for which the selected coding<br />

is not available, coding is automatically set to OFF.<br />

Remote command:<br />

​[:​SOURce]:​BB:​DM:​CODing​ on page 245<br />

Modulation<br />

The modulation type is set in the "Modulation section". The parameters offered depend<br />

on what is currently selected. The "More..." button opens a submenu for displaying the<br />

user-defined mapping.<br />

Modulation Type - Digital Modulation<br />

Selects a modulation type.<br />

The associated symbol mapping is displayed in the "More..." submenu (see ​chapter<br />

5.10.2.1, "Modulation Types - Custom Digital Mod", on page 51).<br />

If the "coding" that is set is not possible with the chosen modulation type, "coding" is set<br />

to "Off".<br />

For selection "Variable FSK", the deviation of each symbol can be set in the "More..."<br />

submenu.<br />

Remote command:<br />

​[:​SOURce]:​BB:​DM:​FORMat​ on page 245<br />

Load User Mapping - Digital Modulation<br />

Selects user defined mapping table. This opens the "Select List File User Mapping" window<br />

in which the mapping table can be selected (see ​"User Mapping" on page 54). The<br />

button is only available if modulation type "USER" is selected.<br />

The button "File Manager" calls the "File Manager" menu. The "File" "Manager" menu is<br />

used to display and delete files.<br />

Remote command:<br />
