AD9364 Zynq Xilink MATLAB TOOLBOX Problem with spectral lobes

Hi,

 

I am trying to calibrate the FMCOMMS4 (AD9364 transceiver) board, programmed with Xilinx Zynq MATLAB toolbox. After  setting up the 'GainSource' parameter to 'Manual' with 0 dB, I send a tone with the function generator, try to receive it in RXA port and then I plot the spectrum of the tone. I have checked it out that when I choose a 'BaseBandSampleRate' higher than 10 MHz two strange lobes appear at the ending of the effective filter (I think it is caused by decimate). Do you know how to eliminate it?.

 

Thanks. I attach some photos about the problem and the MATLAB code.
