Where can I find an affordable spectrum analyzer for cell phone frequencies?
I need a spectrum analyzer that I can use to examine the bands used by cell phones. (I am looking for interference sources). I am especially interested in the frequency ranges used by AT&T and Verizon (though I don't know off the top of my head which those are) My searches so far have found the dirth-cheap Wi-Spy, (which I already own) but it only covers Wi-Fi frequencies and not cell frequencies. My searches have also located Tektronix products which can analyze the frequencies I care about (and most other frequencies too) but they cost $60,000 new, so they are out of the question. Where is the middle ground? I need cell phone spectrum analysis. I can pay in the hundreds, maybe even in the thousands, but I sure as heck can't pay in the tens of thousands.
Gargspy is right for the cost of a spectrum analyzer. Your best bet for one that is less expensive is at either a "ham fest" where amateur radio people get together to sell equipment, as well as socialize, or find out what is going on with the hobby. Another place would be government auctions. The competition for such as this is going to be very steep since such equipment is in high demand. One way is to get a Tektronix 7500 series oscilloscope, and then find the analyzer module that fits it. Cell frequencies start a 1,000 MHz, with a default frequency 850 MHz.
