     Hello,everyone,I have a question during the developing of AD9361.

     I use ZC702 and fmcomms5 platform ,no-os software. I tune the rx sample rate to 40Mbps, rx LO frequency 2.4G .I send a  2.402GHz single tone signal from aglient signal source ,then I analyze the received data in the matlab, just as the figure shows.The calculated frequecy is 2.026MHz, the frequency offset is 26KHz.

      I want to know whether the frequency offset is  in a reasonable range? Is there any methods can be take to reduce the frequenct offset?
