Acquisition
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.
