[:SOURce<hw>]:AM[:DEPTh] <Depth>
The command sets the modulation depth of the amplitude modulation in percent. The
modulation depth is limited by the maximum peak envelope power (PEP).
Parameters:
float
0 to 100

sets the AM modulation depth to 15 percent
Example:
SCPI conformUsage:
[:SOURce<hw>]:AM:EXTernal:COUPling <Coupling>
The command selects the coupling mode for the external modulation input (EXT MOD)
in the case of amplitude modulation.
Parameters:
AC|DC
AC
The DC voltage component is disconnected from the modulation
signal.
DC
The modulation signal is not changed.
AC
<Coupling>
*RST:
AM:EXT:COUP AC
Selects the coupling mode AC for external amplitude modulation.
Example:
SCPI conformUsage:
[:SOURce<hw>]:AM:SENSitivity?
The command queries the input sensitivity of the EXT MOD input in %/V. The command
is only effective if the external modulation source is selected (SOUR:AM:SOUR EXT). The
returned value depends on the modulation depth setting (SOUR:AM:DEPTh). This value
is assigned to the voltage value for full modulation of the input.
