modulation is enabled. As only one modulation is
allowed at any one time, other modulation modes
will be disabled when FM modulation is enabled.

SOURce[1]:FM:SOURce
Source Specific
Command
Description Sets or queries the modulation source as internal
or external. Internal is the default modulation
source.
Note If an external modulation source is selected,
modulation depth is limited to ± 5V from the MOD
INPUT terminal on the rear panel. For example, if
modulation depth is set to 100%, then the
maximum amplitude is +5V, and the minimum
amplitude is -5V.
