The LT354 is the newest member of the Waverunner-2 Series of digital oscilloscopes from LeCroy. It provides the power you need to quickly view, measure, and evaluate your signals — accurately and reliably — all at a reasonable price. The Waverunner-2 series is designed to save engineers valuable time in troubleshooting signals and problem solving.

The Waverunner LT354 provides 500 MHz of bandwidth at 1 GS/s into 2 Mpts of acquisition memory per channel (with the the “ML” memory option). This allows single-shot capture of long, complex signals at high sampling rates on all 4 channels with no interleaving required. The external trigger input is useful to trigger on an additional signal. Altogether, the Waverunner-2 series provides the bandwidth, sample rate, acquisition memory, and processing power needed to test signals with excellent fidelity, resolution, and precision.

Each Waverunner-2 oscilloscope is an integrated and powerful system providing the capability to CAPTURE, VIEW, and ANALYZE (simple as well as complex) signals. The Wavepilot toolbar offers easy access to popular measurement and analysis functions. 

The Wavepilot button provides easy access to analysis capabilities which improve your productivity. You get one-touch operation of features that automatically sets up cursors, creates context-sensitive displays of up to 26 waveform parameters, histograms, and trends. Functions like JitterTrack and TrackView help you track down timing and signal integrity problems right to the source. 

Select the best configuration for your needs and budget. If you want to expand in the future, LeCroy provides reasonably priced upgrades for both hardware and software.

Signal Viewing

Display 

The bright, clear 8.4" TFT LCD color display makes it easy to see text and signals. Select Full Screen, and the entire display is devoted to signal viewing to enhance signal details. QuickZoom automatically displays up to eight traces on multiple grids with maximum S/N ratio. With a press of the green “Analog Persist” button, choose the intensity-graded or color-graded view and quickly visualize the signal’s history. 

Analog Persistence with “History” 

The newest function available in Analog Persistence mode is “History.” You can select “History” to store and view up to 4,000 sequential acquisitions with individual display of each event and trigger time down to 1 ns resolution. Scan forward and backward to search for signal errors, then analyze when and why the error occurred. 

Quick Zoom 

Press QuickZoom to explore signal relationships and inspect or magnify selected regions of a waveform. Use AutoScroll to scan and view details on signals of up to 2 Mpts.

Signal Analysis 

Wavepilot 

Wavepilot is the easy-to-access signal analysis feature on new Waverunner-2 oscilloscopes. Wavepilot gives you the most direct way to view measurement cursors, or a group of 26 signal parameters or evaluate the signal with graphs including Histograms, TrackView, or the frequency spectrum (FFT) view.

Graph 

Press Wavepilot and select “Graph” for quick and simple setup of measurements, FFT or TrackView trends. Select optional histograms or JitterTrack for accurate and precise results when evaluating critical timing parameters, crosstalk, and signal integrity problems in high-speed designs. All JitterTrack views are synchronized to the signal so you can track problems to the source. 

Cursors and Automatic Measurements

Press Wavepilot and select “Parameters” to view up to 26 of the 28 standard waveform parameters (over 40 are available with optional analysis packages). It’s context-sensitive, so if you select FFT, histogram or TrackView, it shows the right parameters with the right units. Select the Cursors button for instant access to cursor measurements.

Signal Analysis Solutions 

Optional software packages customize the Waverunner-2 scopes with powerful signal analysis solutions including power measurements, disk drive and media development, wireless and network communications, and computer design. Press Wavepilot and select Analysis Packages for direct access.

Custom DSO 

Get your work done fast by automating your analysis with your own customized setups and applications. CustomDSO applications can be created offline and stored on a floppy disk, or on the optional hard drive and memory cards for quick access.
