RX DC Offset

Projects LimeSDR

Hello,

I am trying to receive a signal using LMS API c++ library. Whenever I plot the samples I received, there is always a random DC offset occurring somewhere randomly. I tried to calibrate RX as well but no help although the calibration finishes successfully. Any thoughts on this?
