The Rigol DS1000 series of oscilloscopes are popular with hobbyists for good reason: they provide decent specs at a low price. However, their spectrum analysis abilities are lacking. While these ...

The Zoom FFT is interesting because it blends complex down conversion, lowpass filtering, and sample rate change through decimation in a spectrum analysis application. The Zoom FFT method of spectrum ...

EE’s electronic test instrument coverage achieved critical mass in the mid-1980s, including a spectrum analyzer story in the August 1986 issue and subsequent August issues into the 1990s and beyond.

With the ever-expanding adoption of wireless in embedded systems of all types, there’s no question that having spectrum analyzer capability in an oscilloscope is a time-savings convenience for ...

Everyone’s a critic, but it’s hard to argue with success. And that’s exactly what [agp.cooper] has with his ATtiny85-based spectrum analyzer devices. The “normal” way to build a spectrum analyzer is ...

The Compact Spectrum Analyzer (CSA) from MPB srl of Italy is a real-time FFT handheld spectrum analyzer. It features a 7-inch color touchscreen and coverage of spectrum from 10 Hz to 4 GHz. It ...
