[:SOURce[]][:MOD]:AM:DSSC
Syntax [:SOURce[]][:MOD]:AM:DSSC {ON|1|OFF|0}
[:SOURce[]][:MOD]:AM:DSSC?
Description Turn on or off the AM carrier waveform suppression function of the specified
channel.
Query the on/off status of the AM carrier waveform suppression function of the
specified channel.
Parameter Name Type Range Default
[] Discrete 1|2 1
{ON|1|OFF|0} Bool ON|1|OFF|0 OFF
Explanation  DG1000Z supports the normal amplitude modulation and double sideband
suppressed carrier (DSB-SC) amplitude modulation. In the normal amplitude
modulation, the modulated waveform contains the carrier waveform
components. As the 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 point, all the modulated waveform carry
information. This method is called double sideband suppressed carrier
modulation.
 When [:SOURce[]] or [] is omitted, the system sets the related
parameters of CH1 by default.
Return Format The query returns ON or OFF.
Example :SOUR1:AM:DSSC ON /*Turn on the AM carrier waveform suppression function
of CH1*/
:SOUR1:AM:DSSC? /*Query the on/off status of the AM carrier waveform
suppression function of CH1 and the query returns
ON*/
