It used to be a spectrum analyzer was an exotic piece of gear. However, these days it is pretty common for a scope to have some ability to do the job — that is, plot amplitude versus frequency.

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 ...

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 ...

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 ...

At the recent InfoComm show in Las Vegas, Kaltman Creations introduced Invisible Waves, a new series of PC-based RF spectrum analyzers specifically designed for the pro audio and video industries.

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.

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 ...

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 ...

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 ...
