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%.

 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.

 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%.
