Noise filters based on so-called dynamical decoupling pulse sequences can suppress decoherence in quantum systems. Turning this idea on its head now provides a new technique for studying the noise ...

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 ...

Anritsu has enhanced its VectorStar vector network analyser (VNA) family with spectrum analysis capabilities creating the world’s first single sweep VNA-spectrum analyser solution capable of ...

Anritsu has introduced a multi-functional spectrum analyser for field use. Covering 9kHz to 4GHz, MS2080A, as it is called, is suited to “interference hunting and 5G/LTE base station installation and ...

Juergen Grau has taken to Kickstarter once again to launch and raise funds for his new analogue audio spectrum analyser which takes the form of the Magilyzer Mk II, which builds upon previous designs ...

Anritsu has announced a pair of cable and antenna analysers with options up to 6GHz, one with a spectrum analyser. “RF cable runs continue to be an integral part of radio communication base stations, ...

As hobbyist and commercial drones become ever cheaper and more ubiquitous, security and government officials around the world are stepping up efforts to detect the presence of drones or unmanned ...

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 ...

Juergen Grau data the new DIY audio spectrum analyser called the Magilyzer EM800 complete with EM800 Magic Eye tubes, which has this week launched via Kickstarter and is now available to back with ...

Always wanted one of those wickedly-cool spectrum analysers to find the best channel for your wireless router, but don't have the readies to ever afford such a device? How's about a relatively simple ...

Spectrum analysers give great insight into your sounds by deconstructing the so-called frequency spectrum to show the levels of the various frequencies present in an audio signal. Displayed as a graph ...

[Lixie Labs] are no strangers to creating many projects with LEDs or other displays. Now they’ve created a low latency music visualizer, called the Sensory Bridge, that creates gorgeous light shows ...
