The settings for the internal modulation source (LF generator) are made in the
SOURce:LFOutput subsystem.

[:SOURce<hw>]:AM[:DEPTh] <Depth>
Sets the modulation depth of the amplitude modulation signal in percent.
Parameters:
<Depth> float
Range: 0 to 100
Increment: See data sheet
*RST: 30
Example:
AM 15PCT
sets the 15% AM modulation depth
Manual operation: See "AM Depth" on page 172
[:SOURce<hw>]:AM:EXTernal:COUPling <Coupling>
Selects the coupling mode for the external amplitude modulation signal.
Parameters:
<Coupling> AC | DC
AC
Uses only the AC signal component of the modulation signal.
DC
Uses the modulation signal as it is, with AC and DC.
*RST: AC
Example:
AM:EXT:COUP AC
selects the coupling mode AC for external amplitude modulation.
Manual operation: See "AM External Coupling" on page 172
[:SOURce<hw>]:AM:SENSitivity?
Queries the input sensitivity of the externally applied signal for amplitude modulation.
The sensitivity depends on the set modulation [:SOURce<hw>]:AM[:DEPTh].
The returned value reports the sensitivity in %/V. It is assigned to the voltage value for
full modulation of the input.
Return values:
<Sensitivity> float
Range: 0 to 100
