 I used a program called pcbWeb (http://www.pcbweb.com/) to design the circuit and PCB, then send the files off to one of the distributors included in the program. The whole process was very easy and the 
 printed boards arrived after about 10 days. To my surprise I hadn't made any major mistakes on the board design and the fabrication was flawless. I found that it was cheaper to buy knock-off Arduino Nano
 off eBay for about $4 each than to buy the individual AT328, clock crystal, and power regulator, and USB socket components. It looks amateurish but it gets the job done.<br>

 ## Testing
 The AD9833 datasheet reports an output range of 0 Hz to 12.5 MHz. I found that the output stability and voltage break down quite a lot as frequency approaches 10 MHz, and greatly deteriorate by 12.5 MHz.
