DS90UB948电磁兼容测试，测试频段为30M-200M，测试时190M附近RE辐射超标，用频谱近场探头测试为948的辐射，190M频点附近该现象是否正常？

    Hi AARON,

    Just to clarify how was this measurement isolated to the 948? 
    What is the PCLK for this application ?
    Do you mind clarifying what serializer used in this application?
    Have you tried turning off back light driver to see if that helps?
    What have you done as far as ABA testing to isolate it to the 948?
    Any near field testing has been done? Probing, etc.?


    You could send over the schematic for review as well.

    Regards,
    Fadi A.
