Amplitude Modulation (AM)

Amplitude Modulation (AM)
A modulated waveform consists of a carrier waveform and a modulating
waveform. In , the amplitude of the carrier is varied by the amplitude
AM
of the modulating waveform. The function generator will accept an
internal modulating signal, an external modulating signal, or both.
For more information on the fundamentals of Amplitude Modulation,
refer to chapter 7, "Tutorial".

To Select AM Modulation

• The
annunciator turns on when
AM
• Only one modulation mode can be enabled at a time. When you
enable , the previous modulation mode is turned off.
AM
• Front-Panel Operation: Enable
modulation parameters. Press
using the present settings for the carrier frequency, modulating
frequency, output amplitude, and offset voltage.
• Remote Interface Operation: To ensure proper operation, you should
enable after you have set up the other modulation parameters.
