All I was going to build was the interface. The DDS module is too cheap to make in house, and test equipment rarely needs FCC approval. The DDS module can only put out a 0 to 5 volt signal, which is about 120 mW. A lot of signal generators produce higher outputs and don't require FCC approval, since they don't radiate the signal when used properly.

Bear in mind that "real scientists" tend to sneer at the "fuzzy subjects" which include English.
