[:SOURce<hw>]:FM:SENSitivity?

Queries the input sensitivity of the externally applied signal for frequency modulation. The returned value reports the sensitivity in Hz/V. It is assigned to the voltage value for full modulation of the input signal.

The sensitivity depends on the set [:SOURce<hw>]:FM[:DEViation].

Return values: 
<Sensitivity>
float
Range: 0  to  max
Increment: 0.01
Example: FM:DEV 5E3

sets a modulation deviation of 5 kHz.

FM:SENS

queries the input sensitivity at the external modulation input.

Response: 5E3

since the voltage value for full modulation is 1V, the resulting sensitivity is precisely 5000 Hz/V.

Usage: Query only
Options: Option R&S SMA-B20 or R&S SMA-B22
Manual operation: See "FM Sensitivity"
