Supported PSG-A Series
[:SOURce]:AM[1]|2:EXTernal[1]|2:COUPling AC|DC
[:SOURce]:AM[1]|2:EXTernal[1]|2:COUPling?
This command sets the coupling for the amplitude modulation source through the
selected external input connector.
AC This choice will only pass ac signal components.
DC This choice will pass both ac and dc signal components.
*RST DC
Key Entry
Ext Coupling DC AC
Remarks The command does not change the currently active source or switch the
current modulation on or off. The modulating signal may be the sum of
several signals, either internal or external sources.
