Immediate
This softkey is one of the choices in the FM Sweep Trigger menu. Choosing
Immediate immediately triggers swept-sine frequency modulation in a continuous
mode. To stop the sweep, choose a different trigger such as
Ext, or set the
waveform to something other than
Swept-Sine.

Internal
This softkey lets you internally generate an AC-coupled, frequency modulation
signal.
The internal source has multiple uses but can be used for only one modulation at a
time. If, for example you were using the internal source in an amplitude
modulation configuration for
AM Path 1, and then you configured FM Path 2 to
also use the internal source, the signal generator would turn off
AM Path 1 and
assign the internal source to your
FM Path 2 configuration.
