RATio
Couples the deviation ratio of both paths
*RST: UNCoupled
Example: See Example "Using combined LF signals" on page 695.
Manual operation: See "Deviation Mode" on page 353
[: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 695.
Manual operation: See "Total Deviation" on page 354
[:SOURce<hw>]:FM:RATio <Ratio>
Sets the deviation ratio (path2 to path1) in percent.
Parameters:
<Ratio> float
Range: 0 to 100
Increment: 0.01
*RST: 100
Example: See Example "Creating a frequency modulated RF signal"
on page 694.
Manual operation: See "Ratio Path2/Path1" on page 354
[:SOURce<hw>]:FM:MODE <Mode>
Selects the mode for the frequency modulation.
Parameters:
<Mode> HBANdwidth | LNOise
HBANdwidth
Selects maximum range for modulation bandwidth.
LNOise
Selects optimized phase noise and spurious characteristics with
reduced modulation bandwidth and FM deviation.
*RST: HBANdwidth
