ADRV9371-w/PCBZ cards from analog devices and FPGAs zc 706 from Xilinx

H ey,

I have just ADRV9371-w/PCBZ cards from analog devices and FPGAs zc 706 from Xilinx.
My first step is to use my cumputer to control one ADRV9371 card conected and FPGA to transmit something.
I use Wide Tuninig Range AD9371 Eval Brd Tranceiver Evaluation Software.

I capture signal through receiver channel Rx1 and Rx2, but data is saving equally.

Can someone help me?

Thank you for your answers
