This means that the shape and amplitude of the waveform has to repeat itself at a certain point in time.
And these repetitions have to continue until the oscilloscope is able to correctly reconstruct and display the measured waveform.
Signals measured by the real-time sampling method does not have this restriction. However, most signals generated by man-made machines are indeed repetitive waveforms [2].
Another restriction is that during ETS, it is not possible to take single shots of non-repetitive events like glitches or spikes.
Figure 1 shows a non-repetitive signal captured with an oscilloscope running in ETS mode.
