AM
The modulated waveform consists of two parts: the carrier waveform and the
modulating waveform. In AM, the amplitude of the carrier waveform varies
with the instantaneous voltage of the modulating waveform. The parameters
for the AM are in Figure 2- 29
Press Mod →Type→ AM, to enter the following menu.

Term Explanation
Modulation Depth
The amplitude range (also called ‘Percentage Modulation’). Modulation depth
varies from 0% to 120%.
In the 0% modulation, the output amplitude is the half of the set one.
In the 100％ modulation, the output amplitude is the same with the
set one.
