Amplitude Modulation Subsystem ([:SOURce])
:AM[1]|2...
Supported PSG-A Series
[:SOURce]:AM[1]|2...
This prefix enables the selection of the AM path and is part of most SCPI commands
associated with this subsystem. The two paths are equivalent to the
AM Path 1 2 softkey.
AM[1]
AM Path 1 2 with 1 selected
AM2
AM Path 1 2 with 2 selected
When just AM is shown in a command, this means the command applies globally to both
paths.
Each path is set up separately. When a SCPI command uses AM[1], only path one is
affected. Consequently, when AM2 is selected, only path two is set up. However, the
depth of the signals for the two paths can be coupled.
Depth coupling links the depth value of AM[1] to AM2. Changing the deviation value for
one path will change it for the other path.
These two paths can be on at the same time provided the following conditions have been
met:
DUALsine or SWEPtsine is not the selection for the waveform type
each path uses a different source (Internal 1, Internal 2, Ext1, or Ext2)
