I try to generate my own, simple QAM waveforms and load them to ADRV9375 on ZC706 board to watch how does it work (without DPD feature for now). When I load generated waveform (attached to this post) by TES GUI, spectrum analyser reports acceptable Avg_RMS EVM = 1.5%. Loading the same waveform by DPD GUI causes Avg_RMS EVM = 7%. In both cases sample rates are the same 61.44 MSPS. DPD GUI is doing something with the waveform while loading - i observed filtering, but maybe something more? Is DPD adapted only for LTE custom waveforms or I do something wrong?
