Note: When choose the external modulation, the menu Depth , AMFreq and
Shape will hide.
In the Graph Mode, the waveform is shown in figure 2-42.

Term Explanation
Modulation Depth
The Amplitude Range (also called “Percentage Modulation”). Modulation Depth
varies from 0% to 120%.
z In the 0% Modulation, the output amplitude is the half of the set one.
z In the 100% Modulation, the output amplitude is the same with the set one.
z For an external source, the depth of AM is controlled by the voltage level of the
connector connected to the [Modulation In]. +5V corresponds to the currently
set depth 100%.
