A new version is the result of two years of development by best experts in digital audio. RMAA raises the bar of comfort and functionality for spectrum analyzers. That's why it is a program of choice ...

Radio seems to be an unofficial theme for The Hackaday Prize, with a few wireless frameworks for microcontrollers and software defined radios making their way into the quarterfinal selection.

Like most modern radio communications devices, wireless local-area networks (WLANs), RFID tags, and 3G cellular systems rely on complex modulations that require specialized signal-analysis ...

Back in the 1960s, when I started working in radio broadcast engineering, an oscilloscope was my “eye” on what was happening with equipment. That tool served me well and is still in daily use in my ...

For a long time, spectrum analyzers and scanning receivers have been widely used in EMI laboratories. The technical capabilities of these instruments are similar to those of a classic stepped EMI ...

It’s the latest in instrumentation for the well-appointed shop — an acoustically coupled fast Fourier transform tachometer. Sounds expensive, but it’s really just using a smartphone spectrum analyzer ...
