AD9142A makes complex modulation with I/Q data of base signal.
I am not majoring in communication engineering. So how to generate I/Q data of a square waveform or SINC waveform for AD9142A ?
If you are using the DPGDownloader software, you can generate a square waveform using the "Add Generated Waveform" dropdown menu as shown below. You can then fill in your data rate and desired output frequency of the square wave as well as other formatting settings for your configuration, including selecting the 'Generate Complex Data (I & Q)" checkbox which will generate the I and Q vectors for you to use and download to the part to play out.
Actually, this question is not about DAC. Recommend you to refer the Matlab help doc.
