TOTal
Couples the deviation depth of both paths.
RATio
Couples the deviation depth ratio of both paths
*RST: UNCoupled
Example: See Example"Using combined LF signals" on page 414.
Manual operation: See " Deviation Mode" on page 77
[:SOURce<hw>]:AM:RATio <Ratio>
Sets the deviation ratio (path#2 to path#1) in percent.
Parameters:
<Ratio> float
Range: 0 to 100
Increment: 0.1

[:SOURce<hw>]:AM<ch>:SENSitivity <Sensitivity>
Sets the sensitivity of the external signal source for amplitude modulation in %/V.
Parameters:
<Sensitivity> float
Range: 0 to 100
Increment: 0.1
*RST: 30
Example: See Example"Using an external signal source" on page 414.

12.15.1.3 SOURce:FM subsystem
Option: R&S SMBB-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.
// Reset the instrument to start from a defined state
