A sampling oscilloscope captures the time domain waveform at discrete time intervals using a [[Sampler|sampling circuit]]. These captured voltages are then either stored in an analog fashion (integrator circuits and CRTs) or digitized and processed digitally. | A sampling oscilloscope captures the time domain waveform at discrete time intervals using a [[Sampler|sampling circuit]].

A distinction is made between real-time and equivalent time sampling. Real-time sampling requires a sampling rate of at least twice the highest signal bandwidth to capture the signal without [https://en.wikipedia.org/wiki/Aliasing aliasing artifacts].
