memory in ".arb" format (you can overwrite the original file or save the currently
edited waveform).
21.3 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 to select "Modulation"
and then press down the knob to select it. You can also press Type continuously or
enable the touch screen to select it.
Press Type, rotate the multifunction knob to select the desired modulation type,
and then press down the knob to select it. You can also press Type continuously or
enable the touch screen to select it. The available modulation types include AM, FM,
and FSK.
21.3.1 AM
AM (Amplitude Modulation), namely the amplitude of the carrier waveform changes
with that of the modulating waveform, as shown in the figure below.
