Hi Evan, Dave,toggle quoted messageShow quoted text
I looked at the 'specs' as shown on the Amazon page Dave referenced. It didn't include information that Evan has given. The big deal about a spectrum analyzer is a requirement to display very weak signals that live right next to very strong signals. Good shielding is also required. There is nothing in those specs I saw to give clues about those requirements for the measurements we want to make. Maybe the RF Explorer can do the harmonics as Evan says. Maybe others can report their results.
We can get at least some usable information from just about any 'spectrum analyzer' system including the RTL-SDR dongle and our computer sound cards. Evan an old fashioned 'wobbulator' But maybe not good enough for the kind of "measurements" we want to make here. It could be better than nothing at all. Or it could even be worse than nothing at all. Worst case is they can say "something is there". Determining just what and how much may be out of reach. Let's see what others have to say about that RF Explorer. I just ordered some 'toys' from Amazon and that RF Explorer caught my attention. I took a pass on that.
