The RTL-SDR dongles get most of the love from people interested in software-defined radio, but the Pluto is also a great option, too. [FromConceptToCircuit] shares code to turn one of these radios ...

Optical spectrum analyzers (OSA) can divide a lightwave signal into its constituent wavelengths. This means that it is possible to see the spectral profile of the signal over a certain wavelength ...

Every machine has its own way of communicating with its operator. Some send status emails, some illuminate, but most of them vibrate and make noise. If it hums happily, that’s usually a good sign, but ...

The Rigol DSA815 spectrum analyzer The idea of “seeing” RF has always intrigued me, but short of some futuristic goggles, an RF spectrum analyzer is about as close as one can get. And for those of us ...

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 ...

Let’s say a corporate engineer or a consultant is coming to your station to diagnose and repair a problem using an RF spectrum analyzer. This would be a great time to schedule a meeting with your ...

This application note discusses on using a passive probe which is commonly used in an oscilloscope, only in this case, it will be used for a spectrum analyzer. A portion of the preferences 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 ...

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 ...

Spectrum analysers can be invaluable when it comes to frequency shaping. We show you why… When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. While ...
