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 ...

[Camilo] built a spectrum analyzer to use with his audio system (translate). The hardware is quite simple, using an op-amp, microcontroller and LCD display. He chose an LMV324M low-voltage op-amp ...

WiPry Clarity from Oscium is a tri-band Wi-Fi spectrum analyzer that lets you view wireless activity on Wi-Fi 6/6E, as well as legacy Wi-Fi bands. Using the free Windows or Mac software, the tool ...

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 ...

Via proprietary DPX waveform image processing, the mid-range RSA3000B and RSA3408B series real-time spectrum analyzers provide a unique live RF view of the spectrum. Reportedly, DPX processing ...

While [Vinod] says he’s not an expert in this sort of thing, we really like his audio spectrum analyzer build from a simple microcontroller and LCD display. It is a well-studied fact that every audio ...

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 ...

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 ...

While it’s seldom necessary (post-installation, anyway) to test the physical-layer behavior of a wired LAN infrastructure, the same cannot be said for wireless LANs. Many elements, including fading, ...

Fen Technology and Swires Research have jointly developed a combined Terrestrial (DVB-T) and Satellite (DVB-S) spectrum analyzer, based on a suite of STMicroelectronics Digital TV and memory products.
