Sample rate
Sets the number of recorded waveform points per second. The sample rate is the recip-
rocal value of the resolution and thus also depends on the acquisition time and the record
length. It considers the samples of the ADC, the additional waveforms points resulting
from resolution enhancement (interpolation and equivalent-time sampling), and the
reduction of waveform points by decimation.

ADC sample rate
Shows the number of points that are sampled by the ADC in one second. The ADC
sample rate is a constant of the instrument.

Resolution
Sets the time between two waveform samples. A fine resolution with low values produces
a more precise waveform record.

Record length
Indicates the number of waveform samples that build the waveform across the acquisition
time.
