Portable Spectrum Analyzer

Your normal test equipment probably isn’t too useful for projects that involve UHF/VHF frequencies. This portable spectrum analyzer is an affordable tool that operates from 50 to 950 MHz. The compact dsPIC33FJ256GP710-based design employs high-speed A/D conversion, digital down conversion, numerically controlled oscillators, finite impulse response filters (FIRs), and FFT.
