BB:DM:FORM ASK
selects the ASK modulation type.
BB:DM:ASK:DEPT 50 PCT
sets a modulation depth of 50 percent.
Example:
[:SOURce<hw>]:BB:DM:CODing <Coding>
The command selects the modulation coding.
If the modulation type selected (:BB:DM:FORM) is not possible with the coding that has
been set, it is automatically set to OFF (:BB:DM:COD OFF).
When a standard is selected (:BB:DM:STAN), the coding is set to the default value.

*RST:
BB:DM:COD GRAY
selects GRAY coding. This coding is valid for all modulation types.
Example:
[:SOURce<hw>]:BB:DM:FORMat <Format>
The command selects the modulation type.
If the coding that is set (:BB:DM:COD) is not possible with the modulation type selected,
it is automatically set to OFF (:BB:DM:COD OFF).
When a standard is selected (:DM:STAN), the modulation type is set to the default value.
