Most modern spectrum analyzers have a hybrid architecture that lies between the traditional swept-tuned model and one that only uses FFT techniques. For very large spans with a wide RBW, a swept-tuned ...

Modern pulsed radar systems use advanced waveform and modulation characteristics to obtain greater range resolution, enhanced clutter suppression and superior target recognition. Specifically, ...

It’s Darren again, filling in for Jit. Last week, we discussed FFT functionality and VSA (vector-signal-analysis) software on a scope. Sometimes I hear this called spectrum analyzer software, but in ...

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 ...

Most RF and microwave analyzers have a superheterodyne architecture that down-converts the input signal to a lower IF, generally using several IF stages at different frequencies. Digital technology ...
