USB spectrum analyzer
in [Design]

From: Raveninghorde on 3 Oct 2009 13:57 I'm looking for a USB spectrum analyzer for occasional use. My immediate requirement is to cover the range 100kHz to 3MHz but up to 30MHz would be good. Any recommendations based on personal experience?

It's an unserved market. You can get one based on a Winradio but IIRC it'll set you back north af $1500. Then there's the Icom R1500 for $600 or sans controller pod as the PCR1500 for around $500. Not much out there in terms of (reliable) spectrum analysis software, so to make it fancy you'd have to write some. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

If you feel ambitious this is a home brew 1GHz one. http://www.scottyspectrumanalyzer.com/msaorig.html Then again if you have a DSO they come with FFTmay be good enough for your purpose.

Most DSO have spectrum analyses capabilities. Just don't expect a wide dynamic range. -- Failure does not prove something is impossible, failure simply indicates you are not using the right tools...

I'd love to have a dynamic signal analyzer equivalent that went up to at least 30 MHz. You could even do network analysis.
