• Sampling: In this acquisition mode, the oscilloscope samples the
signal in evenly spaced intervals to construct the waveform. This
mode accurately represents signals most of the time.
Advantage: You can use this mode to reduce random noise.
Disadvantage: This mode does not acquire rapid variations in the
signal that may occur between samples. This can result in aliasing,
which may cause narrow pulses to be missed. In these cases, you
should use the Peak Detect mode to acquire data.

• Peak Detect: Peak Detect mode capture the maximum and
minimum values of a signal Finds highest and lowest record points
over many acquisitions.
