[:SOURce<hw>]:FM:DEViation:MODE <FmDevMode>
Selects the coupling mode. The coupling mode parameter also determines the mode
for fixing the total deviation.
Parameters:
<FmDevMode> UNCoupled | TOTal | RATio
UNCoupled
Does not couple the LF signals.
The deviation values of both paths are independent.
TOTal
Couples the deviation of both paths.
RATio
Couples the deviation ratio of both paths
*RST: UNCoupled
Example: See Example"Using combined LF signals" on page 418.
Manual operation: See " Deviation Mode" on page 74
[:SOURce<hw>]:FM:DEViation:SUM <FmDevSum>
Sets the total deviation of the LF signal when using combined signal sources in fre-
quency modulation.
Parameters:
<FmDevSum> float
Range: 0 to 40E6
Increment: 0.01
*RST: 1E3
Example: See Example"Using combined LF signals" on page 418.
Manual operation: See " Total Deviation" on page 75
[:SOURce<hw>]:FM:RATio <Ratio>
Sets the deviation ratio (path2 to path1) in percent.
Parameters:
<Ratio> float
Range: 0 to 100
Increment: 0.1
*RST: 100
Example: See Example"Creating a frequency modulated RF signal"
on page 417.
Manual operation: See " Ratio Path2/Path1" on page 75
