Term Explanations
Real-time Sampling: DS1000CA has Real-time sampling rate up to
2GSa/s. At the time base 20ns or faster, the oscilloscopes use the sine(x)/x
interpolation to expand the horizontal time base.
Equivalent sampling: Known as Repetitive sampling to get up to 20ps of
horizontal resolution (equivalent 50Gsa/s). This mode is good for observing
repetitive signals, and it is not recommended for single-shot or pulse.
Normal Acquisition: Oscilloscope acquires signal by equal time interval.
Average Acquisition: Apply averaging to your signal to remove
uncorrelated noise and improve measurement accuracy. Reduces random
or uncorrelated noise in the signal display. The averaged waveform is a
running average over a specified number of acquisitions from 2 to 256.
Peak Detect: Peak Detect mode captures the maximum and minimum
values of a signal. Finds highest and lowest record points over many
acquisitions.
