I asked this earlier as part of other question (on which I got answer, but on this part not).
and transmit signal from one antenna to another on same board I do
not get sinus waveform. I tried to change test.c script, also
I tried to use look up tables for generation of waveform insted
of default DDS approach (a changed part in main.c to call dac_dma_setup()...)
But whatever I do I do not get sinus waveform in Vivado Analyzer. I do not
even get how DAC works, because it behaves really strange (if I send square
waveform I got something like square waveform but not square waveform).
My sinus wave looks like it is modulated on some carrier... Could anybody explain
me what is wrong (maybe there is problem on FMCOMMS1). Results are below.
Thank you in advance on answer,
