    Proper equipment required was right. But not stand alone spectrum analyzer. Other wise you are getting noise level present in your entire set up.

    To figure out noise figure of certain LNB. A complete setup is required; professional spectrum analyzer , swept generator and noise generator. Moreover, noise figure of an LNB is not constant on its entire band.

    Practically is not that easy.
    work to learn but dont work to earn....
