I have already written a few posts on AD9850 DDS testing. Here are some more testing. I had possibility to test my signal generator circuit with Rigol DSA 815 RF spectrum analyzer. I improved my test circuit from previous tests by putting it inside case. I also replaced Arduino UNO with Arduino model with FTDI →
Few days ago I tested AD9850 DDS module in home in hope to some day have a working signal generator using it. The initial tests went well, so I could plan the next step. I was already doing some information searching to make decision if I should do the controlling using web interface (with Ethernet →
For some RF tests I sometimes need to generate different higher frequency signals than normally available from general purpose function generator. For this purpose I bought a cheap AD9850 module to generate different frequency RF signals. This AD9850 module can generate frequencies in 0-40 MHz frequency range (sine wave output). For initial testing I successfully →

Electromagnetic Warfare Is Here article tells that a briefcase-size radio weapon could wreak havoc in our networked world. In the 2001 action movie Ocean’s Eleven, criminals use an electromagnetic weapon to black out a portion of Las Vegas. It might have seemed to bevVery futuristic at the time, but nowadays the threat is real and →
