This video shows how to use the FFT function of RIGOL oscilloscopes. The FFT function allows the user to measure the frequency and time domain of the signal waveform, at the same time. In this ...

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 recently had a discussion about measuring noise density (i.e., op amp noise) with a digital oscilloscope. While we certainly use oscilloscopes to measure time domain noise, as can be seen on nearly ...

The modern oscilloscope is no longer just a time-domain measurement tool, as test equipment vendors integrate logic, protocol, and spectrum analysis functions. (Image courtesy of Thinkstock). As ...

Rohde & Schwarz has added a series of mixed-signal scopes to its HMO1002 oscilloscope family of lower cost instruments. The supplier describes these as true mixed-signal oscilloscopes which can ...
