The Hackaday Superconference is all about showcasing the hardware heroics of the Hackaday community. We also have a peer-reviewed journal with the same goal, and for the 2018 Hackaday Superconference ...

Using a spectrum analyzer to measure noise signals requires several additional factors, such as sensitivity or how well the instrument can measure small signals. The analyzer’s noise floor specifies ...

The RSA3408A can display frequency-domain plots over time, a feature that lets you see how the frequency content of a signal changes. That's important for viewing signals on devices such as cell ...

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 ...

There are many ways to look at the world, and many ways to look at electronic signals. Many fundamental instruments, such as voltmeters and oscilloscopes, use a time-oriented approach. They provide ...

The easiest way to envision a spectrum analyzer is to begin with an oscilloscope that plots magnitude versus time. Then swap frequency for time—and voilà—a spectrum analyzer! A gross simplification ...

[Debraj] wrote to us describing a project he recently completed – a simple, compact spectrum analyzer using a 16-bit dsPIC microcontroller. The analyzer is fed an analog signal, which is passed ...
