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

Testing an AD9850 DDS module

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
