Signal Views
WaveScan provides distinct views of your signal:

Source View highlights all occurrences of edges that meet your
criteria.

Scan Overlay places all captured edges one on top of the other in a
separate grid. You can apply monochromatic persistence in this
view.

Scan Histogram provides a statistical view of edges that meet your
search criteria.

Zoom View allows you to expand a waveform feature vertically and
horizontally; to apply further processing (using Measure); to Store it,
or to apply a descriptive Label to the feature (as shown on the
Actions portion of the trace dialog).
NOTE: The number of grids displayed varies from one to three grids depending on
which views are enabled. WaveScan handles this function automatically, and there
is no option to move traces from one grid to another, as would be the case under
normal (non-WaveScan) operation.
Search Modes
Use the Mode control to select an appropriate Search to locate anomalies
during acquisition. When each of the following modes are selected, a
corresponding right-hand dialog provides additional controls. The following
modes are available:

Edge Mode – Designed for detecting the occurrence of edges;
selectable slope and level.

Non-monotonic Mode – For detecting threshold re-crosses;
selectable slope, hysteresis, and level.

Runt Mode – For detecting pulses failing to cross a threshold;
selectable polarity and thresholds.

Measurement Mode – For filtering and performing parameter
measurements.
