ADVANCED ANOMALY DETECTION
WaveScan Advanced Search
Locate unusual events in a single
capture or scan for an anomaly across
many acquisitions over a long period
of time. WaveScan provides powerful
isolation capabilities that hardware
triggers cannot provide.
Select from more than 20 search
modes to nd events on any analog
or digital channel. Since the scanning
modes are not simply copies of the
hardware triggers, the utility and
capability is much higher. There is no
frequency trigger in any oscilloscope,
yet WaveScan allows for frequency to
be quickly scanned, notifying the user
upon a shift in frequency. Searching can
be done based on measured waveform
parameters, runts, and non-monotonic
edges as well as digital patterns.
WaveScan quickly and efciently scans
millions of events looking for unusual
occurrences. Search and scan results
can be seen with annotations directly on
the waveform or in the interactive table.
Quickly zoom to an event to see more
details by simply touching it in the table.
Combining a fast waveform update rate of 130,000 waveforms/second with History mode waveform playback, Pass/Fail
Mask Testing and WaveScan search and nd, the WaveSurfer 3000 is an outstanding tool for waveform anomaly detection.
A powerful set of triggering capabilities ensures that once a problem is detected it can be isolated and analyzed.
Powerful Triggering
Good triggering is essential for effective
debug and with a powerful combination
basic and advanced triggers the
WaveSurfer 3000 ensures that even
the most challenging problems can be
isolated. Basic triggering like edge and
width are great for every day operation.
Advanced triggers like runt or interval
help isolate anomalies quickly. Qualied
triggering allows for conguring a
trigger across multiple channels.
With the MSO leadset connected,
powerful logic triggering can be set up
to catch a parallel pattern of up to
16 digital channels. Analog channels
can be added to the pattern trigger
to congure an analog-digital cross
pattern, mixed signal trigger.
Beyond the standard oscilloscope
triggering, unique serial data triggering

Pass/Fail Mask Testing
Built-in pass/fail mask testing quickly
identies problems and marks the
location. A history of the pass/fail
results can be displayed on the screen.
There are four different conditions that
can be selected to specify a passing
condition: All In, All Out, Any In, and Any
Out. When a failure is found, one or
more of the following actions can
be selected to be performed to
record the results: save a waveform,
stop the acquisition, output and
audible alarm, pulse the aux output
port, save a hardcopy or even save a
LabNotebook entry.
When the acquisition is running, failures
are displayed as a red trace, however
when the acquisition is stopped, a
failure indicator is displayed to clearly
show all failing points. Masks can either
be created using the offline mask maker
utility or created based on a reference
waveform and specifying horizontal and
vertical deltas.
