    Hello.
    

    I am testing with ADRV9002 and ZedBoard with transmit and receive looped back.
    

    

    I tested with transmit local frequency as 1500.5 MHz and receive local frequency as 500 MHz.
    

     
    

    

    I could see the aliasing of harmonics on the IIO oscilloscope.
    

     
    

    

    Next, I changed the analog low-pass filter setting in TES from first order to second order, but there was no difference in the waveform.
    

     
    


    I expected characteristics similar to Figures 138 and 139 in the ug-1828.
    First Order with 27dB attenuation at 10^9Hz, and Second order with 60dB attenuation at 10^9Hz.
    

    

    Do I need to make any other changes to the JSON file to enable the analog low pass filter?
