Sampling process
Acquisition is the process of sampling an
analog signal, converting it into digital data,
and assembling it into a waveform record,
which is then stored in acquisition memory.
Real-Time sampling
In real-time sampling, the instrument digitizes
all of the points it acquires using one trigger
event. Use real-time sampling to capture
single-shot or transient events.
Interpolated Real-Time sampling
In interpolated real-time sampling, the
instrument digitizes all of the points it acquires
using one trigger event. If the instrument
cannot acquire enough samples for a
complete waveform at the maximum real-time
sample rate, it interpolates. Use interpolated
real-time sampling to capture single-shot or
transient events.
Equivalent-Time sampling
The instrument uses equivalent-time sampling
to extend its sample rate beyond its real-time
maximum sampling rate. Equivalent-time
sampling is only used if Equivalent Time is
selected and the time base is set to a
sampling rate that is too fast to create a
waveform record using real-time sampling.
The instrument makes multiple acquisitions of
a repetitive waveform to obtain the sample
density required for one complete waveform
record. Thus, equivalent time sampling should
only be used with repetitive signals.
