hello everyone    

i use ad9361 with no-os system at fmcomms2+zc706. and i select TDD mode,and set rx2tx2 as 1.


i connect signal source at rx1. and the signal source provide sine signal. than in the code, i do this.


adc_capture(1024, DDR_BASEADDR);

      data = Xil_In32(DDR_BASEADDR+(n*4));
      data_I= data & 0xFFFF;

      data_Q= (data >> 16) & 0xFFFF ;



than i use some method to save data_Ito file. last i use matlab to draw data_I, but it's not sine curve.


why? or what's wrong with me? can somebody help me.
