ODULATION
The AFG-2225 Series Arbitrary Function Generators are able to
produce AM, FM, FSK, PM and SUM modulated waveforms.
Depending on the type of waveform produced, different modulation
parameters can be set. Only one modulation mode can be active at
any one time. The function generator also will not allow sweep or
burst mode to be used with AM/FM. Activating a modulation mode
will turn the previous modulation mode off.
