Scope FFT and waveform math functions take on RF measurements

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 ...

Know the Limitations of Your Scope’s FFT Capabilities

An oscilloscope’s FFT function can tell you the frequency content of an acquired signal. Most digital scopes–even those costing less than $400–have the ability to perform a Fast Fourier Transform (FFT ...

FFT function versus vector-signal-analysis software on a scope

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 ...

FFT Brings Spectrum Analysis To The Scope

Many of today's digital oscilloscopes include fast-Fourier-transform (FFT) capability for frequency-domain analysis. This feature is especially valuable for oscilloscope users who have limited or no ...
