Amplitude Modulation (AM)
A modulated waveform consists of a carrier waveform and a
modulating waveform. An example of the AM waveform is
shown in
Figure 2- 14 . In AM, the amplitude of the carrier is
varied by the instantaneous voltage of the modulating
waveform. The amount of amplitude modulation is called the
modulation depth which refers to the portion of the
amplitude range that will be used by the modulation.

To Select AM
The U2761A allows only one modulation mode at a time. The
U2761A does not allow modulation when sweep is enabled.
