I have Xilinx Kintex-7 FPGA DSP Development Kit which includes KC705 and FMC150. The reference design is running on the board. FMC150 DAC output is connected to the FMC150 ADC input (loopback). The send data and the received data does not have the same amplitude and they are not even close to each other. (DAC output (fixed_16_15) is 0.99 and ADC input is 0.6) What is the reason for that? How can I fixed this issue?
