As technology marches on, gear that once required expensive lab equipment is now showing up in devices you can buy for less than a nice dinner. A case in point: those tiny displays originally sold ...

The RTL-SDR dongles get most of the love from people interested in software-defined radio, but the Pluto is also a great option, too. [FromConceptToCircuit] shares code to turn one of these radios ...

Keysight's new handheld analyzer enables 120-MHz IQ streaming for gap-free signal capture and navigating crowded, complex RF ...

While it’s seldom necessary (post-installation, anyway) to test the physical-layer behavior of a wired LAN infrastructure, the same cannot be said for wireless LANs. Many elements, including fading, ...

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 ...

The crowded RF spectrum, compounded by the explosion in application spaces joining the cloud, demands advanced development tools able to provide deeper insights into signals and their measurement. Our ...

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 ...

Designers of high-frequency RF equipment and systems are finding that performance is everything when it comes to spectrum analysis. They need to be able to see small signals in the presence of large ...
