Manual operation: See " Total Deviation" on page 88
[: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 572.
Manual operation: See " Ratio Path2/Path1" on page 88
[: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
Example: See Example "Creating a frequency modulated RF signal"
on page 572.
Manual operation: See "Mode" on page 89
[:SOURce<hw>]:FM:SENSitivity?
Queries the sensitivity of the externally supplied signal for frequency modulation. The
sensitivity depends on the set modulation deviation.
Return values:
<Sensitivity> float
Sensitivity in Hz/V.
It is assigned to the voltage value for full modulation of the input.
Range: 0 to max
Increment: 0.01
Example: See Example "Using an external signal source" on page 573.
Usage: Query only
