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 ...

One of the most useful pieces of test gear to become generally available to the average broadcast engineer in the last 20 years or so is the spectrum analyzer. This electronic tool, while still rather ...

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 ...

Today's spectrum analyzers aren't your father's instruments. Thanks to lots of embedded processing power, digital signal processing (DSP), and new analog front-end circuitry, the latest round of ...

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 ...

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 ...

One tool that many Wi-Fi techs have on their wish list is an RF spectrum analyzer. That's because when tasked with tracking down an RF interference problem like that shown in Figure B, other than ...

When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Tracking down interference with conventional spectrum analyzers can be difficult if the ...

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 ...

The easiest way to envision a spectrum analyzer is to begin with an oscilloscope that plots magnitude versus time. Then swap frequency for time—and voilà—a spectrum analyzer! A gross simplification ...

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 ...
