4. MODULATION

The FGX-2220 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.

4-1. Amplitude Modulation (AM)

An AM waveform is produced from a carrier waveform and a modulating waveform.
The amplitude of the modulated carrier waveform depends on the amplitude of the
modulating waveform. The FGX-2220 function generator can set the carrier
frequency, amplitude and offset as well as internal or external modulation sources.
