Simple Scalar Network Analyzer you can build for less than $20

Demonstration of a simple scalar network analyzer using an Arduino, a DDS module and an AD8307 power detector. The UI is derived from a project by PA2OHH. Tested with Windows 7 but should run on Linux as well. Source code is on github: https://github.com/rheslip/Scalar_Net... Project documentation on my blog: rheslip.blogspot.ca
