[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 ...

Spectrum analyzer mistake shows how span and RBW settings can make RF measurements look right while quietly leading you ...

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 ...

Tracking down interference with conventional spectrum analyzers can be difficult if the interference is intermittent. This week Tektronix announced the H500 and SA2500 handheld spectrum analyzers with ...

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 ...

Ghosts of DTV signals could easily be seen on analog TV screens, but with DTV, they are invisible on the TV screen. DTV ghosts, also known as echoes, can only be seen on the screen of a spectrum ...

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 ...

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 ...

Digital circuitry can produce a wide range of harmonic frequencies and spectrum analyzers can show you this RF frequency spectrum (power or voltage), versus frequency. They are the one piece of gear ...

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 ...
