Double Sideband Suppressed Carrier
DG4000 supports two kinds of amplitude modulation (normal amplitude
modulation and Double Sideband Suppressed Carrier (DSB-SC) amplitude
modulation). In normal amplitude modulation, the modulated waveform contains
carrier components. As the carrier components do not carry information, the
modulation efficiency is low. To improve the modulation efficiency, you can
suppress the carrier components on the basis of the normal amplitude modulation.
At this point, all the modulated waveform components carry information. This
mode is called double sideband suppressed carrier modulation.
Press DSSC to turn on or off the double sideband suppressed carrier modulation.
By default, normal amplitude modulation is used.
