I am shopping for an entry level spectrum analyzer with a tracking generator. I spend most of my time below 50MHz working with amateur radio gear. I have been looking at used Instek GSP-810s. At 400 bucks or so, especially compared to the SDR-based homebrew unit I am using now, they seem like a pretty good deal. I've looked at old used gear too but, honestly, I don't know enough about the high end stuff to know a good deal from bad and I certainly don't have the expertise (yet) to repair such stuff.
I've noticed though that there are very few reviews of the entry SAs in general and the 810 in particular. Anyone have one? Use one? Have an opinion? Is it just silly to think I can get a decent SA for under a thousand bucks? two thousand? Is there some used HP, etc SA I really should consider instead, as painful as it will be for my wallet?
Thanks in advance! - b
