UNCoupled
Does not couple the LF signals.
The deviation depth values of both paths are independent.
TOTal
Couples the deviation depth of both paths.
RATio
Couples the deviation depth ratio of both paths

13.16.3.3 SOURce:FM subsystem
Option: R&S SMM-K720
The FM subsystem contains the commands for setting the frequency modulation.
Example: Creating a frequency modulated RF signal
Using the internal LF generator, the following command sequence configures a fre-
quency modulated signal.
