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 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.

Advantage: In this way, the oscilloscope can acquire and display narrow pulses, which

may have otherwise been missed in Sample mode.

Disadvantage: Noise will appear to be higher in this mode.
