    STEADY SIGNAL INSIDE 3G UMTS Envelop.

    I am investigating a RFI inside a 3G UMTS spectrum frequency. The 3G UMTS starts around 903 - 908 Mhz.



    My question is inside the UMTS envelop of 5 MHz, should there be any steady signal observed ? I have using a Portable Reciever ( R&S PR100) to do offline scanning and monitoring to identify the interfering signal ?

    I have observed 3 x steady signals within the 5 MHz UMTS enveloped .

    I have attached 2 screen shot from the PR 100 equipment.

    Please help
