Real time vs Equivalent time sampling mode
The oscilloscope automatically switches between
two sampling modes, Real-time and Equivalent-
time, according to the number of active channels
and sampling rate.
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).
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.
