A noise figure analyzer is better for this, but a spectrum analyzer is more useful as a general lab instrument.

I have already checked this website. but i could not conclude anything from it. We have spectrum analyzer, we are purchasing noise figure analyzer, but the vendors are quoting for spectrum analyzer or signal analyzer, we have spectrum analyzer so why would i need them... so i want to know the advantages of NFA over SA.
