3.1.10 Sum Modulation(SUM)
In SUM, the modulated waveform generally is composed of carrier wave and modulation wave. The
output waveform is obtained by the sum of product of carrier amplitude and modulation factor and
product of amplitude of modulation wave and modulation factor.
The modulation mode of the two channels is mutually independent. You can configure same or
different modulation mode for channel 1 and 2.
Select SUM
Press Menu → Type →
SUM successively to use SUM function (if Type is not highlighted, press
soft key Type to select). After SUM function is used, UTG2000B function/arbitrary waveform
generator will output modulated waveform with the current modulation waveform and carrier
wave.
