When evaluating the dynamic performance of precision analog-to-digital converters (ADCs) using fast Fourier transform (FFT) analysis, coherent sampling typically is used to accurately measure the ...

In the process of debugging and validating both digital and RF designs, the oscilloscope Fast Fourier Transform (FFT) function and a variety of other math functions can prove valuable to designers ...

I’m out traveling this week, so my good buddy Darren McCarthy, an RF guru here at Tektronix, is going to fill in for me. My university math teacher always told me (in a thick Russian accent) that when ...

Virtually all scopes today provide the FFT (Fast Fourier Transform) as a standard feature, but in my experience, few users know how, when, or why to use it. And if they do, they rarely use it well.
