For spectrum analyzers lacking a tracking generator, this broadband RF noise source is affordable and will help measure a ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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.

Provided you have an NTSC-compatible TV you can build yourself a really inexpensive spectrum analyzer. From there you just need one trivial piece of hardware to complete this build. [Bruce Land] has ...
