I bought the AD9172 EBZ and the ADS7v2.
I'm trying to generate data with the DAC. It works fine with the DPG-generated waveforms, but when I want to load my own file, the results are not quite what I was looking for.
I think that I get the problem : when DPG downloads a waveform, I need to check 'Generate Complex data (I&Q)' and uncheck 'Unsigned data', in way to see a single ray.
Indeed the DAC needs I and Q data for each channelizer. So, after checking the data mapping in the JESD204 transport layer, I tried to make one single file with both I and Q data (which I got from DPG 'Save to file' option) interleaved. The results are still not correct.
Furthermore, in the DPG help, I can see that multichannel files are not supported. Does that mean that I cannot send data to my DAC from a file? If not, how can I send I and Q to the DAC?
If this is a limitation of DPG, how to send your own data to the AD9172 (from a file)?
Thank you in advance
