7.How to Implement Sampling Setup
Click to show Function menu, choose "Sampling" to set sampling mode.
Sampling Mode Description
Sampling Normal sampling mode.
Peak Detect
Use to capture maximal and minimal samples. Finding highest and lowest
points over adjacent intervals. It is used for the detection of the jamming
burr and the possibility of reducing the confusion.
Average
It is used to reduce the random and don't-care noises, with the editable
number (1
≤ number ≤128) of averages.
Figure: Normal sampling mode display, in which no burr can be detected.
Figure: Peak Detect mode, under which the burrs on the falling edge of the square wave, can be detected and the noise is heavy.
Figure: The displayed waveform after the noise is removed under the Average Mode, in which the average number of 16 is set.
