Lecroy 24Xs-A Overview

The Everyday Oscilloscope that's Easy to Use In today's busy test and measurement environment, there's now a refreshing solution for routine circuit testing and debugging. It's the new WaveSurfer Xs oscilloscope. Designed to make testing circuits virtually "friction free", this new oscilloscope offers an easy-to-learn and use interface, a big screen, small footprint and very attractive pricing in the 400-600 MHz range. Here's how good it really is.

A Super Fit with your Working Style The WaveSurfer Xs oscilloscope is designed for easy and reliable everyday testing, day in and day out. Its simple, easy-to-use, touch-screen interface and its dramatically improved sample rate, will quickly earn it a permanent place on your bench.

A Marvelous Fit to Your Bench The rules of scope design have been radically altered-in your favor. The large screen ensures that every nuance of your signal is clear, sharp and easy for you to interpret. The small footprint lets you keep it within easy reach. It's an optimum configuration.

A Match to Your Budget You'll be hard pressed to find a scope in its class that offers a better combination of value and performance. With 2-channel and 4-channel configurations and bandwidths of 400 MHz and 600 MHz, the new WaveSurfer Xs oscilloscope can sample waveforms at up to 2.5 GS/s.

LeCroy WaveStream™ Fast Viewing Mode The new LeCroy WaveStream fast viewing mode provides a vibrant, intensity graded (256 levels) display with a fast update to closely simulate the look and feel of an analog oscilloscope. The WaveStream mode is most helpful in viewing signals that have signal jitter or signal anomalies. Since the sample rate in WaveStream mode can be as high as 2.5 GS/s, it is an excellent runt or glitch finder.

Timing jitter is often visually assessed to understand approximate behavior. WaveStream mode makes it easy to understand jitter on edges or in eye diagrams. WaveStream mode 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™ Advanced Search 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 (frequency, rise time, runt, duty cycle, etc.), apply a search condition and begin scanning.

The best trigger won’t find all unusual events—a more powerful capability is sometimes needed. 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. However, WaveScan allows for “frequency” to be quickly “searched or scanned.” This allows the user to accumulate a data set of unusual events that are separated by hours or days, enabling faster debugging.

When used in multiple acquisitions, WaveScan builds on the traditional LeCroy strength of fast processing of data. A LeCroy X-Stream scope will quickly scan millions of events, looking for unusual occurrences, and do it much faster and more efficiently than other oscilloscopes can.

WaveScan in WaveRunner®, WavePro®, WaveMaster®, and Serial Data Analyzers also contains Scan Histo and Scan Overlay capability. Found events can be overlaid in a Scan Overlay view to provide a quick and simple comparison of events. In addition, measurement-based scanning modes (like the frequency example given above), permit Scan Histograms to show the statistical distribution of the found events. These analysis tools simplify understanding and enable faster debug.

Superior Signal Capture The WaveSurfer Xs oscilloscope beats short memory scopes hands down when it comes to the debugging of common circuit problems like clock/data issues and timing errors. It provides all the detail needed by delivering more than 100x the capture time at full sample rate compared to other oscilloscopes in its class. It effectively eliminates the trade-off between high sample rate and long capture time.

Extend WaveSurfer Xs Capabilities with these Options

Mixed Signal Oscilloscope Option: This option creates the first mixed signal oscilloscope that combines 4 analog channels with 32 digital channels.

MathSurfer: Additional math functions, chained math functions, rescaling of units, and enhanced FFT capability.

Advanced Trigger Package: Includes runt, slew rate, qualified edge, qualified state, interval, and dropout triggers.

ET-PMT Electrical Testing: Transforms the WaveSurfer Xs into a dedicated mask testing device for manufacturing and field testing of electrical telecom signals.

The Interface Redefines Simplicity The WaveSurfer Xs interface and its operations have all been carefully considered to provide the busy engineer with a GUI that is smooth, transparent, and easy to use. Whether you are triggering on a runt or looking for an anomaly, most common measurements are only one touch away. When it comes to easy running, the WaveSurfer Xs oscilloscope sets the standard.

Smooth Cursor Control You can use dedicated front panel cursor knobs to position your cursors at any time without invoking special menus. You can quickly choose your cursor by using the "type" button. Apply them to any signal, zoom, or math trace. You won't find an easier to use set of cursors on any other oscilloscope.

Simple Zooming and Math Zooming is so easy with this scope - simply draw a box around the area to be zoomed (or use the front panel QuickZoom button). Waveform math is also built in and easily applied. In addition, a power spectrum FFT is standard. It can be quickly invoked and easily set up, even by someone not familiar with FFTs.

One Touch Access to 23 Measurements The WaveSurfer Xs oscilloscope fits your working style as comfortably as it fits your bench. Twenty-three basic measurements have been built in to give you quick answers.

Access the measure menu from the front panel. Select your measurement (and source, as necessary). Measurements appear automatically below the grid and never obscure your signal Communicate all the ways you want Document work and share it effectively by:
