I have a quick question for the group about the noise floor of a
spectrum analyzer, hope that with the collective knowledge and
experience somebody can help me out a bit.
We have customer that needed a couple of site surveys done, in order
to detect any possible interference sources on 3 segments
Does anyone have any hands on experience with the Aaronia Spectran
hand-held 1MHz to 7GHz 999-Euro spectrum analyzer? Any comments
appreciated.
