Define the condition of peak search to search all kinds of peak. It can only be judged as peak
when meanwhile meets the value of both "peak excursn" and "peak thresh".

Peak Search
Set the peak which is looked up in peak search is whether the maximum value on the trace or the
peak meets search parameter.
•
Choose "Max Value", then look up the maximum value on the trace.
•
Choose "Parameter", then look up the peak meets the condition of search parameter on the
trace.
•
This set is only valid for the peak search excecuted when press "Peak".
