Carrier Waveform Suppression
DG1000Z supports the normal amplitude modulation and double sideband
suppressed carrier (DSB-SC) 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 base of the normal amplitude modulation. At this
time, all modulated waveform carry information. This method is called double
sideband suppressed carrier modulation. By default, DG1000Z works in the normal
amplitude modulation and users can enable the double sideband suppressed carrier
modulation through pressing the menu key DSSC and selecting “On”.
