trace to be searched on the main WaveScan dialog. For each mode, different controls appear on the
WaveScan dialog, providing additional inputs to the search criteria. Make the appropriate entries in these
fields before starting the search.
Edge Mode
Edge Mode is used for detecting the occurrence of edges. Events that meet the threshold level are
captured and tabulated. When the acquisition is stopped, scan filters can be applied to the edges to find
specific characteristics. Edge Mode settings are:
l Slope. Choose Pos, Neg, or Both.
l Level is (set in...). Choose Percent or Absolute.
l Percent/Absolute Level. Enter a threshold value as a percentage of Top to Base or voltage level.
