LECROY WAVESCAN ADVANCED SEARCH
Since the scanning
“modes” are not simply
copies of the hardware
triggers, the utility and
capability is much higher.
For instance, there is no “frequency”
trigger in any oscilloscope, yet
WaveScan allows for “frequency”
to be quickly “scanned.” This allows
the user to accumulate a data set of
unusual events that are separated by
hours or days, enabling faster debug-
ging. When used in multiple acquisi-
tions, WaveScan builds on
the traditional LeCroy strength of
fast processing of data. A LeCroy
X-Stream oscilloscope will quickly
scan millions of events looking for
unusual occurrences, and do it much
faster and more efficiently than other
oscilloscopes can.
WaveStream Fast
Viewing Mode
WaveStream provides a vibrant, intensity
graded (256 levels) display with a fast
update rate to closely simulate the
look and feel of an analog oscilloscope.
WaveStream is most helpful in viewing
signals that have signal jitter or signal
anomalies, or for applying a visual
check before creating an advanced
trigger or WaveScan setup to locate
an unusual event.
Since the sampling rate in WaveStream
mode can be as high as 5 GS/s (up
to 2.5x that of other oscilloscopes),
it is an excellent runt or glitch finder.
Timing jitter is often visually assessed
to understand approximate behavior.
WaveStream makes it easy to
understand jitter on edges or in eye
diagrams. WaveStream also excels
in allowing you to relate composite
(WaveStream) to single-event (real-time
sampled) behaviors. Just capture in
WaveStream mode, toggle to view
or zoom a single trace, then toggle
back to WaveStream mode.
WaveScan provides powerful isolation capabilities that
hardware triggers can’t provide. WaveScan provides the ability
to locate unusual events in a single capture (i.e., capture and
search), or “scan” for an event in many acquisitions over a
long period of time. Select from more than 20 search modes
to find events on any analog or digital channel or search for a
pattern across multiple digital channels.
