AVR Embedded Antenna Analyser
How to build Antenna Analyser for ham-radio? this project will show you how to build it. The IW3HEV antenna analyser is a relatively simple antenna analyser designed by pa3ckr. The main part of the project is Microcontroller AVR Atmel ATMega32. It has a 1-60MHz DDS signal generator and uses a homebrew directional coupler plus the Analog Devices AD8302 IF Gain Phase detector. Controlled through a PC’s parallel port it can measure SWR, Return-loss, Phase and Z, but It cannot determine the real and imaginary parts of Z however. src
