Waveform acquisition concepts
Acquisition concepts
The Acquisition system sets which data points are used to acquire waveforms.
Acquisition hardware
Before a signal is displayed, it must pass through the input channel where it is scaled and digitized. Each channel has a
dedicated input amplifier and digitizer. Each channel produces a stream of digital data from which the instrument extracts
waveform records.
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.
