Dear Sir,

         We now use AD7192 in our design. When we  took this board to do EMC RS test(10v/m,100-200Mhz), the date range from 4.0pH to 4.35pH, failed to pass the test.

        Below is my schematic, can you kindly suggest that do i need to modify several parts for better EMC performance?Seems we need to seperate the AVdd and Dvdd power supply. 

        Sorry for trouble you guys.
