WaveScan™ Advanced Search and
Analysis
Teledyne LeCroy’s WaveScan Advanced Search and Analysis tool can be used
in the following ways:

Capture and Search - Take a single acquisition, set a search mode, and
apply a filter (i.e., create a search condition).

Scan - Set a search mode, apply a filter, and take multiple acquisitions to
scan for unusual events (i.e., create a software condition for a hardware
trigger).

Analyze - Use ScanOverlay and ScanHisto to further analyze the filtered
events.
You can select from more than 20 search modes (frequency, rise time, runt,
duty cycle, etc.), apply a search condition (slope, level, threshold, hysteresis),
and begin scanning in a post-acquisition environment. Since the scanning
modes are not simply copies of the hardware triggers, the capability is much
greater.
For instance, there is no frequency trigger in any oscilloscope, yet WaveScan
allows frequency to be quickly scanned for.
You can accumulate a data set of unusual events that are separated by hours
or days, enabling faster debugging. The events are time stamped and indexed
in a table from which you can select them for viewing individually.
You can also set actions to occur automatically when unusual events are
found: stop the acquisition, emit an audible beep, output a pulse, print the
screen, save the waveform, or create a LabNotebook entry.
Refer to your oscilloscope’s on-line Help for more information about
WaveScan.
WaveScan Signal Views
WaveScan provides several views of your signal:

Source view highlights all occurrences of edges that meet your criteria.

Zoom view allows you to expand a waveform feature vertically and
horizontally. This can be used to apply further processing, to store it, or to
