[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 ...

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 ...

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 ...

Built for rugged conditions, the PSA Series 4 provides comfortable one-handed operation in a compact and ultra-lightweight ...

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 ...

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 ...

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 ...

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, ...
