Real time vs Equivalent time sampling mode
Backgrounds
The oscilloscope automatically switches between
two sampling modes, Real-time and Equivalent-
time, according to the number of active channels
and sampling rate.
Real-time
sampling
One 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
(250MSa/s or lower).
Equivalent-time
sampling
Multiple numbers of sampled data are
accumulated to reconstruct a single waveform.
Restores greater waveform details but takes longer
to update the waveform. This mode is used when
the sampling rate becomes higher than 250MSa/s.
The maximum equivalent-time sampling rate is
25GSa/s.
