Real time vs Equivalent time sampling mode
Background The oscilloscope automatically switches between two sampling modes, Real-time
and Equivalenttime, according to the number of active channels and sampling
rate.
Real-time
sampling
Once sampled data is used to reconstruct a single waveform. Short-time events
might get lost if the sampling rate gets too high. This mode is used when the
sampling rate is relatively low (1GSa/s or lower).
Equivalent-time
sampling
Multiple numbers of sampled data are accumulated to reconstruct a single
waveform. ETS restores more waveform detail but takes longer to update the
waveform. This mode is used when the sampling rate becomes higher than
1GSa/s. The maximum equivalent-time sampling rate is 25GSa/s.
