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.
