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 ...

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 ...

How good is your existing oscilloscope's fft function with the $10 diy emc H-field probe compared with a dedicated spectrum analyser? Dave tries the diy emc probe with half a dozen different low-cost ...

No instrument, whether in the time or frequency domains, is suitable for all use cases. Signal/spectrum analyzers shine for ensuring standards conformity. Oscilloscopes tend to be more versatile, ...

Pass/fail testing is an analysis function of an oscilloscope that shows whether waveforms meet a set of defined criteria. The criteria are defined by a series of one or more qualifying conditions that ...
