Hi Carlo, Your questions are about 2 calibrations: DC offset (affects DC component) and I/Q gain/phase calibration (affects mirrored spectra). My understanding is that the B200 calibrations are handled automatically such that there is nothing to do from "tx_waveforms" or even from direct UHD API calls. So, I can't think of anything you can do to reduce these artifacts. Can you provide a picture of the spectrum you are seeing or perhaps comment on the dBc levels of the DC component and mirrored spectra? Rob
