AM Off On
Supported PSG-A Series
This softkey toggles the operating state of the amplitude modulation for whichever AM
path configuration you have selected.
There are two paths for amplitude modulation which can be simultaneously enabled as
long as they use different sources (Internal 1, Internal 2, Ext1, or Ext2). The modulation
signals from both paths are summed internally for composite modulation.When
amplitude modulation is on, the
ΑΜ
annunciator is turned on in the display.
Preset Off
Choices Off or On

Remarks Although you can enable amplitude modulation with this key, the RF
carrier is modulated by the enabled modulation only when you have
also set
Mod On/Off to On.
AM Path 1 2
Supported PSG-A Series
This softkey enables you to select an amplitude modulation path. AM Path 1 and 2
define two standard amplitude modulation configurations which can be used together.
AM Path 1 and AM Path 2 are summed internally for composite modulation. Either path
can be switched to any one of the modulation sources: Internal 1, Internal 2, Ext1, or
Ext2. All modulation types can be simultaneously enabled, except FM with
Φ
M. AM,
FM, and
Φ
M can sum simultaneous inputs from any two sources. Any given source can
only be routed to one activated modulation type.

Choices AM Path 1 AM Path 2

Remarks The RF carrier is available at the RF OUTPUT connector when you
set
RF On/Off to On. Set Mod On/Off to On to modulate the RF carrier
with the modulations that you have enabled.
