Here is an example for using Peak Detect function, the input is a standard test 

square  waveform.  You  can  see  the  "burrs"  on  the  falling  edge  of  signal  is 

detected with noise when it is turned on. 

 

 

Figure 48.

 Peak Detect mode. 

 

 

Figure 49. 

Normal 

ACQU Mode

 display, in which no burr can be detected.
