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 ...

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 ...

Frequency domain analysis provides a powerful tool for assessing the performance of devices and networks. By viewing the amplitude of the signal across a range of narrow frequency channels, designers ...

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 ...

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 ...

Having a scope in a home lab used to be a real luxury, but these days, its fairly common for the home gamer to have a sophisticated storage scope (or two) hanging around. Dedicated spectrum analyzers ...

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.

ThinkRF Corp., a software-defined spectrum analysis solution provider, has released the ThinkRF R5700 Real-Time Spectrum Analyzer with GNSS. Unlike other handheld portable spectrum analyzers, the ...

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 ...

I am, as I’m sure you know, a huge fan of Wi-Fi-oriented spectrum analyzers. My favorite has always been Cisco’s Spectrum Expert, and Fluke, who now own AirMagnet, have been selling their version of ...

A hardware device or software used to examine the frequency and power components of a signal. It provides more information than an oscilloscope, because it can display the signals over a range of ...
