③ Waveform Leakage: Due to low sampling rate, the reconstructed waveform not reflect the actual
signal. As shown in Figure 10-3.

10.2 Acquisition Mode

Acquisition mode is used to control
switch acquisition
(1) Normal Sampling
The signal is sampled and reconstructed with equal time intervals. For most waveforms, this mode can
perform the best display.
(2) Peak Sampling
The maximum and minimum values of the input signal are found at each sampling interval, and these
values to display the waveform. The oscilloscope can acquire and display a narrow pulse, otherwise the
narrow pulse might be missed in the normal mode. Noise might be enlarged in this mode.
(3) High Resolution
The oscilloscope will averaging the adjacent points of the sampled waveform, it can reduce random noise
from the input signal and generate smoother waveform.
(4) Average
The oscilloscope obtains several waveforms to take the average, and display the final waveform. This
method can reduce random noise.
By changing the acquisition mode setting to observe the waveform changes. If the signal contains large
noise, when the average mode is not adopted and when the 32 times average mode is adopted, the
sampled waveform is shown in the following figure.
