This project is about a single-channel signal analyzer and signal generator controlled over an Ethernet connection. The application(s) run on a PC. The board contains some signal conditioning circuitry and a dsPIC33 plus a Wiznet Wiz550io Ethernet module. It is a kind of simple Red Pitaya, not running Linux and without FPGA programming.
After building a prototype which allowed us to validate the project we decided to make it cheaper. The prototype uses a through-hole version of the dsPIC33 and the Wiznet module unfortunately has changed shape since the design of our prototype PCB. To make things cheaper we opted for an all-SMT design with the Ethernet driver on board. Since then several PCB designs have seen the light one of which will be developed further.
The project has been finished successfully. The digitizer works as expected and the PC software is great. The project is scheduled for publication in the March 2016 edition.
