Real time vs Equivalent time sampling mode
Background GDS-2000 automatically switches between two
sampling modes, Real-time and Equivalent-time,
according to the number of active channel and
sampling rate.
Parameter 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.
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.
