Kaltman Creations has introduced a series of PC-based RF spectrum analyzers it says are designed for the pro audio and video industries. Called Invisible Waves, the analyzers automatically chart open ...

ADELPHI, Md. -- A new quantum sensor can analyze the full spectrum of radio frequency and real-world signals, unleashing new potentials for soldier communications, spectrum awareness and electronic ...

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 ...

Keysight Technologies, Inc. introduced the N99xxD-Series FieldFox Handheld Analyzer, the latest evolution of Keysight’s trusted FieldFox family.

We all love our wireless devices. We want more features, higher data rates, and improved range. These demands, in turn, require advanced digital protocols. Meanwhile, the number of signal sources is ...

The real-time signal analyses possible with Tektronix's latest spectrum analyzers give engineers a new toolbox for developing radio frequency (RF) applications. Thanks to an internal memory of up to ...

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 ...

EE’s electronic test instrument coverage achieved critical mass in the mid-1980s, including a spectrum analyzer story in the August 1986 issue and subsequent August issues into the 1990s and beyond.

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.

U.S. Army researchers are developing a quantum sensor capable of detecting electromagnetic emissions across frequency bands and at far greater ranges than traditional receivers and are considering ...

Spectrum analyzer: “a frequency-domain oscilloscope that displays the energy received at its input as a function of frequency.” Not long ago, this definition worked quite well. Now, though, it is far ...

CAMBRIDGE, Mass.--MIT engineers have built a fast, ultra-broadband, low-power radio chip, modeled on the human inner ear, that could enable wireless devices capable of receiving cell phone, Internet, ...
