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 ...
Like a lot of hardware tinkerers, [dexter2048] has a Rigol DS1052E oscilloscope sitting on his bench. One day when trying to coax some information out of the FFT setting, [dexter] threw his hands up ...
In earlier articles, we looked at the basics of fast-Fourier transforms (FFTs) and how to set up an FFT on a modern digital oscilloscope. In this post, we’ll take a brief look at what that modern ...
Because the digital modulation stand-ards used in modern communications systems are defined in terms of in-phase (I) and quadrature (Q) orthogonal components, vector signal analyzers (VSAs) and ...
As one of the most important instruments for electrical test in a lab or in the field, signal and spectrum analyzers serve multiple purposes across a range of applications, from communications, to ...
Modern pulsed radar systems use advanced waveform and modulation characteristics to obtain greater range resolution, enhanced clutter suppression and superior target recognition. Specifically, ...
RIGOL Technologies introduces the new RSA5000 real-time spectrum analyzers to complement the DSA800-TG family of low-cost spectrum analyzers. The devices are based on the new Rigol-developed ...
