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 ...

This spectrum analyzer project seeks to improve the quality of tools available to amateur radio operators. A lot of thought has gone into the design, and those details are shared in the verbose ...

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 ...

Like most modern radio communications devices, wireless local-area networks (WLANs), RFID tags, and 3G cellular systems rely on complex modulations that require specialized signal-analysis ...

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 ...

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 ...

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 ...

A spectrum analyzer is a device that measures and displays Signal amplitude (strength) as it varies by frequency within its frequency range (spectrum). The frequency appears on the horizontal (X) axis ...

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 ...
