[:SOURce<hw>]:AM:DEViation:MODE <AmDevMode>
Selects the coupling mode. The coupling mode parameter also determines the mode
for fixing the total depth.
Parameters:
<AmDevMode> UNCoupled | TOTal | RATio
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
*RST: UNCoupled
Example: See Example "Using combined LF signals" on page 513.
Manual operation: See "Deviation Mode" on page 83
[:SOURce<hw>]:AM:RATio <Ratio>
Sets the deviation ratio (path#2 to path#1) in percent.
Parameters:
<Ratio> float
Range: 0 to 100
Increment: 0.01
*RST: 100
Example: See Example "Creating an amplitude modulated RF signal"
on page 513.
Manual operation: See "Ratio Path2/Path1" on page 84
[:SOURce<hw>]:AM<ch>:SENSitivity:EXPonential <Sensitivity>
For [:SOURce<hw>]:AM:TYPEEXP, sets the sensitivity of the external signal source
for amplitude modulation.
Parameters:
<Sensitivity> float
Range: 0 to 100
Increment: 0.01
*RST: 10
Example: See Example "Using an external signal source" on page 514.
Manual operation: See "Sensitivity" on page 83
