Carrier Waveform Suppression 
 
DG800 supports two types of amplitude modulation: normal amplitude modulation 
and double sideband suppressed carrier (DSSC) amplitude modulation. In the normal 
amplitude modulation, the modulated waveform contains carrier waveform 
components. Because carrier waveform components carry no information, the 
modulation is less efficient. In order to improve the modulation efficiency, the carrier 
waveform components are suppressed on the basis of the normal amplitude 
modulation. At this time, the modulated waveforms all carry information. This 
method is called double sideband suppressed carrier modulation. By default, DG800 
selects the normal amplitude modulation. Tap the DSSC parameter selection field to 
select "On" to enable the double sideband suppressed carrier modulation.
