[:SOURce<hw>]:AM:SENSitivity?
Queries the input sensitivity of the externally applied signal for amplitude modulation.
The sensitivity depends on the set modulation depth, see
DEPTh:LINear
The returned value reports the sensitivity in %/V. It is assigned to the voltage value for
full modulation of the input.
Return values:

Usage:
Manual operation:
[:SOURce<hw>]:AM:SOURce <Source>
Selects the modulation signal source for amplitude modulation.
With linear AM (see

and [:SOURce<hw>]:AM:DEPTh:EXPonential.
float
Range: 0 to 100
AM:DEPT 50
sets a modulation depth of 50 %.
AM:SENS?
queries the input sensitivity at the external modulation input.
Response: 50
since the voltage value for full modulation is 1V, the resulting
sensitivity is precisely 50 %/V.

[:SOURce<hw>]:AM:TYPE
INTernal | EXTernal | INT,EXT
INTernal
Uses the internally generated signal for modulation. To configure
the frequency, use the commands of the
"SOURce:LFOutput
EXTernal
Uses an externally applied modulation signal.
INT,EXT
Uses both, the internal and external modulation signals.
*RST: INT
AM:SOUR INT
selects the internal modulation source.
