FM, AM and M can be applied to the carrier using internal or exter-
nal modulation sources. The internal modulation source is capable of
generating two simultaneous signals into any one of the modulation
channels. The internal and external modulation sources can be simul-
taneously enabled in order to produce combined amplitude and fre-
quency (or phase) modulation.
Internal and external IQ modulation can be applied. In this mode, FM,
AM and M are not permitted.
Optional Pulse modulation can be used in combination with FM, AM,
M and IQ from an external pulse source.
