The LT584 is the new flagship of the Waverunner-2 series of digital oscilloscopes. It harnesses the power of 1 GHz bandwidth, and gives users remarkable cost savings and convenience. With today’s extreme time-to-market pressures, engineers need to evaluate signals quickly and accurately. The Waverunner-2 series accomplishes these critical tasks, and does so at appealing prices. LeCroy’s Waverunner-2 reputation has been built largely upon its intuitive front panel operation which saves engineers time in analysis and problem solving.

The new Waverunner-2 LT584 scope provides 1 GHz of bandwidth at 2 GS/s into 250 kpts of acquisition memory per channel, standard. It can also be equipped with 4 Mpt memory (8 Mpts in 2-channel mode), along with 4 GS/s sample rate in 2-channel mode. This allows single-shot capture of long, complex signals at high sampling rates. There is an external trigger input which can be used 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 both simple and complex signals. The Wavepilot toolbar offers easy access to popular measurement and analysis functions. 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 8 Mpts 
(with option L).

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.
