A demonstration of my Spectrum Analyzer project built using the Beaglebone Black and a USB DVB-T digital television receiver. The receiver is based on Realtek RTL2832U accessed using RTL-SDR library. The demonstration shows the RF spectrum of various sources.
If you are interested in this project, I’ll be releasing the application and source code in GitHub so you can build your own. Probably in a month or two, or sooner, or later.
You can now run this software – ViewRF – on your own hardware. See http://robotics.ong.id.au/2013/08/25/viewrf-rtl-sdr-spectrum-analyzer-for-bbb-software/
