I see there is some discussion about an older large spectrum analyzer. I thought I would share my experience with a new very cheap but quite useful spectrum analyzer.
I have an HP 8558B and an Avcom PSA65C but I find myself using most often an analyzer I picked up recently for less than $250.00.
It is a pocket spectrum analyzer called the RF Explorer. Google it for details.
It covers 15mhz to 2.7ghz, has a built in screen, and also connects to a PC for large screen display and captures.
I have no relation to the people that sell it, I just think it is a valuable useful analyzer for field measurements, and want to let others know of its availability. I never see it discussed anywhere nor is it advertised.
Hope this posting helps you all with your projects and needs.
Thanks, Ken
