Peak
Use the TDR Peak mode to capture events that may 
be intermittent. This mode continuously detects and 
displays the maximum and minimum traces that 
occur from the time that the mode is first selected.  
The ‘live’ trace is also displayed continuously. As a 
new maximum or minimum trace is detected, it will 
replace the previous one on the display.
If the pair being tested is stable (no intermittent 
faults), then the minimum, maximum and “live” 
traces should appear as a single trace.
If any of the control values are changed, the peak 
histories will be erased and new values will begin to 
display.
