Chapter 11 Sampling System
209
In peak sampling mode, when the horizontal time base setting is low, the minimum and maximum sample values
are retained to capture rare events and narrow events (with any noise expanded). This mode will display all pulses
that are at least as wide as the sampling period.
When the time base is set to 200ms and above, the oscilloscope will automatically exit the peak sampling mode and
switch to the normal sampling mode.
Burr or narrow pulse capture
Burr is the rapid change in waveform that is usually narrower than waveform. Peak sampling mode can be used to
view burr or narrow pulses more easily. In the peak sampling mode, narrow burr and transition edges are brighter
than in those in the “normal” sampling mode, making them easier to see.
Applying the peak sampling mode can avoid signal aliasing but show more real noises.
