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.
When the modulation is greater than 100%, the instrument output not greater
than 20 V
PP
.
For an external source, the depth of AM is controlled by the voltage level of the
connector connected to the [Modulation In]. +5V external source corresponds
to the 100
%
internal Modulation.
