Performance
1 GHz Bandwidth
Fast edge characterization, jitter analysis, and other critical circuit analysis opera­tions require high fidelity signal reproduc­tion. The LeCroy 9384 and 9370 Series products offer 1 GHz bandwidth and 9350A Series offers 500 MHz bandwidth for design, debug and testing of high speed circuits.
4 GS/s Digitizing
The 9384, with up to 250 ps real time sample resolution, captures the signal details you need to characterize critical performance parameters like jitter, edge transitions, and fast transient pulses. The 9370 and 9350A Series scopes provide up to 500 ps real time sample resolution.
Up to 8,000,000 Point Record Lengths
LeCroy’s SMARTMemory™ management system automatically optimizes both the sample rate and record length to provide the maximum signal detail over the longest possible time duration, with no mode switching or multiple menu selections. Combine the industry’s longest record lengths—up to 2,000,000 points/channel optional and 50k points/channel standard with SMARTMemory, and you get the LeCroy advantage.
Analysis
LeCroy Digital Oscilloscopes are designed with signal analysis in mind. Processing flexibility, speed, and data protection are not an afterthought. All zoom, math, spec­tral and statistical analysis operations are calculated on a protected data record, assuring that your original data remains uncorrupted and can be used again and again for further analysis.
Waveform Processing
LeCroy’s waveform processing system pro­vides the power to analyze complex sig­nals, even in the presence of noise. Functions such as integration, differentia­tion, rescaling, square root, reciprocal, and logarithms can be chained together for multiple operations. For example, a power measurement can be made by first squaring the signal, then rescaling it, and finally integrating the result; with the cal­culations and display updated after each new acquisition. This result-oriented flexi­bility is only available from LeCroy.
Spectral Analysis
Waveform data can be viewed in the fre­quency domain to reveal hidden informa­tion about your signals. Problems related to noise, spurious signals, phase shifts, and unexpected power dissipation can be easily identified. And, with LeCroy scopes, FFTs and other analysis functions are per­formed on up to 6 Mpoint records, not just the first 10k points.

Statistical Analysis
High resolution jitter analysis, bi-modal fre­quency detection, and amplitude varia­tions over long time constants are just a few of the signal characteristics that can be pin-pointed using statistical analysis. By histogramming any of the 40 paramet­ric measurements and then applying the 18 statistical parameters, hidden informa­tion in waveform data is revealed.

Capture All Events Of Interest!
Ensure that key events are not missed with LeCroy’s SMARTMemory™ Management System and SMARTTriggers™.
Trigger on the Events
of Interest
Having long record length in a DSO is only the first step towards having a really powerful scope. The key to power in a DSO is to manage the memory as part of a completely inte­grated system. SMARTMemory™ is a total memory management system
that dynamically allocates resources of acquisition memory, CPU power, and processing RAM. Add the indus­tries longest record length plus fast sample rates, and the result is a dig­ital oscilloscope that can capture longer time windows with greater detail than any other on the market.
Top trace: 1 ms time window cap­tured using 4 GS/s and 4 MBytes of record length. Bottom trace: zoomed portion showing a .59 ns pulse expanded for detailed examination.
Exclusion trigger, a LeCroy exclusive trigger mode, captures intermittent out-of-tolerance events by triggering on signal characteristics that are outside of user defined boundaries. Trigger only on abnormal events and then use the power of LeCroy’s inte­grated scope to view, measure, ana­lyze and document them.
Above, Exclusion Trigger is set to eliminate pulses within a width of 50 ns. Only pulse widths that are not 50 ns wide will trigger the scope.
Flexible Viewing
Zooming for
Detailed Information
Zoom factors of up to 800,000 times can be achieved for detailed viewing of critical performance char­acteristics, such as rise/fall times, setup and hold times, jitter, and other characteristics of interest. No mode switching or multiple menu selections are required. Simply select the portion of your waveform that you want to examine and use the independent vertical and hori­zontal zoom controls.

Pass/Fail Testing with parameters and waveshape masks assure repeatability and accuracy of char­acterization and test results. The scope will compare live waveform measurement results and waveform data to user-defined limits or wave­form masks. When a failure occurs, the scope can automatically gener­ate a hard copy or store a waveform to floppy disk, PCMCIA hard disk, or SRAM card for later retrieval and evaluation.

The greater the number of waveform data points the higher the frequency resolution attainable in an FFT.
Histogram of timing jitter.
For example problems caused by noise or spurious signals are very difficult to identify and characterize in the time domain, but can be quickly and easily identified using Spectral Analysis (i.e. FFT).
Because LeCroy’s Spectral Analysis functions can be performed on the entire record length, up to 6 Mpoints, much greater frequency detail over the entire signal duration is available than in scopes with FFT functions which only operate on lim­ited portions of the record length.
Histogramming is a more efficient approach to identifying unknown anomalies. By recording waveform data over a long period of time, sta­tistical analysis enables the user to understand the pattern of signal behavior. The result is that hard to analyze waveform parameters, like phase jitter or frequency fluctuations over long time intervals, can be accurately and easily characterized.
LeCroy oscilloscopes offer more than 40 automatic waveform para­meters to select from. Display any 5 measurements on screen for con­tinuous update including a distribu­tion summary of parameter varia­tions of: Average, Lowest, Highest, and Standard Deviation values. All measurement results are displayed below the waveform gradicule for clear viewing of results and wave­forms simultaneously.
The screen above shows Setup and Hold Time Measurement results. The diagram shows the thresholds and levels that define the individual parameter values. Setup and Hold Time are just two of the powerful parametric measurements available on LeCroy’s High Performance Digital Oscilloscopes.
Most standard scope operations are done in the time domain. However, significant insight into what is occurring in a circuit can be gained from viewing waveforms in the frequency domain or with statis­tical analysis.
