[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 ...

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 ...

You would think the hard part about creating a spectrum analyzer using a pint-sized ATTiny85 would be the software. But for [tuenhidiy], we suspect the hard part was fabricating an array of 320 LEDs ...

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 ...

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 ...

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 not-so-distant past, contractors and consultants who wanted to check parameters at a number of FM stations had to lug around a frequency-agile FM monitor and related gear. Today, DSP technology ...

In the fast-paced world of electronics testing and measurement, spectrum analyzers play a critical role in assessing and ...

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, ...
