[Camilo] built a spectrum analyzer to use with his audio system (translate). The hardware is quite simple, using an op-amp, microcontroller and LCD display. He chose an LMV324M low-voltage op-amp ...

You would think the hard part about creating a spectrum analyzer using a pint-sized ATTiny85 would be the software. But for [tuenhidiy], we suspect the hard part was fabricating an array of 320 LEDs ...

The spectrum analyzer has always been a vital tool for the EMC engineer. Until the last few years, these instruments have been rather large and heavy desktop instruments, weighing up to 60 pounds, or ...

Digital circuitry can produce a wide range of harmonic frequencies and spectrum analyzers can show you this RF frequency spectrum (power or voltage), versus frequency. They are the one piece of gear ...

The RF signal analyzer is one of the most versatile tools on the RF test bench, allowing engineers to measure signals ranging from electromagnetic emissions to wireless communications. Most frequently ...

The analysis of RF and microwave signals in the frequency domain used to be the forte of the spectrum analyzer, but now it’s become a choice between signal analyzers and digital oscilloscopes. How did ...
