This portable 2.4 GHz Spectrum Analyzer is built inside a cell phone case, Nokia 3410, and used the phone’s graphical LCD to display measuring results. It uses AVR ATMega8 as main controller and CYWM6935 module. The software is written in C using arv-gcc under Windows (WinAVR). The program runs continuously and make around six [...]

If you have ever attempted to do any projects that involved UHF/VHF frequencies, what is immediately apparent is that your normal test equipment is very inadequate. Standard TV signal space, for example, runs from 50 to 878 MHz. The cost of acquiring test equipment that operate at those frequencies, like signal generators or an [...]

Spectrum analyzers are employed in most of the modern signal processing systems for measuring the distribution of signal energy in frequency. An audio spectrum analyzer is used for measurements in the audible frequency spectrum (from 0 to 20000 Hz) and can be a very powerful tool for keeping a studio well tuned. A Digital, real-time [...]

This 2.4GHz Spectrum Analyzer project build based on Cypress CYWUSB6935 module. The project allows you to monitor the 2.4GHZ ISM band in your immediate vicinity. You can monitor what’s going on and figure out what channel to change your Wi-Fi network to in order for it to keep working when your neighbor rudely sets up [...]
