4-1-2. Real time vs Equivalent time sampling mode

Background

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

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 (250MS/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 250MS/s. The
maximum equivalent-time sampling rate is
25GSa/s.

4-2.

Display

The Display section describes how to configure the display settings:
drawing type, waveform accumulation, contrast adjustment, and grid
settings.
