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 ...

In the fast-paced world of electronics testing and measurement, spectrum analyzers play a critical role in assessing and ...

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 ...

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 ...

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 ...

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.

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 ...

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 ...

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 ...
