Modulation
The built-in Function/Arbitrary Waveform Generator supports amplitude modulation
(AM), frequency modulation (FM), and frequency-shift keying modulation (FSK). A
modulated waveform consists of a carrier waveform and a modulating waveform. The
carrier waveform is the waveform output from the Function/Arbitrary Waveform
Generator, and the modulating signal can be the built-in sine, square, triangle
waveform, or noise signal.
Press Settings > Type, and rotate the multifunction knob
and then press down the knob to select it. You can also press Type continuously or
enable the touch screen to select it.
