7.14.1 SOURce:AM Subsystem
The AM subsystem contains the commands for checking the amplitude modulation.
The settings for the internal modulation source (LF generator) are made in the
SOURce:LFOutput subsystem.

[: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:
<Depth> float
Range: 0 to 100
Increment: See data sheet
*RST: 30
Default unit: PCT
Example:
AM 15PCT
sets the AM modulation depth to 15 percent
[:SOURce<hw>]:AM:EXTernal:COUPling <Coupling>
The command selects the coupling mode for the external modulation input in the case of
amplitude modulation.
Parameters:
<Coupling> AC | DC
AC
The DC voltage component is disconnected from the modulation
signal.
DC
The modulation signal is not changed.
*RST: AC
Example:
AM:EXT:COUP AC
Selects the coupling mode AC for external amplitude modulation.
Usage: SCPI confirmed
