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.
Click Settings → Type to select "Modulation".
Click Type to select the desired modulation type. The available modulation types
include AM, FM, and FSK.
AM
AM (Amplitude Modulation), namely the amplitude of the carrier waveform changes
with the amplitude of the modulating waveform, as shown in the figure below.

1. Select the Modulating Waveform
Click Waveform to select the desired modulating waveform. The available
modulating waveforms include Sine, Square, Triangle, and Noise.
2. Set the Modulation Frequency
Click Frequency, then use the pop-up numeric keypad or scroll with the mouse
to set the frequency of the modulation signal. The available range is from 1 Hz
to 50 kHz.
3. Set the Modulation Depth
The modulation depth refers to the strength of the AM and is expressed in
