Digital oscilloscopes from LeCroy are designed to save engineers valuable time in troubleshooting
and problem-solving.
Each oscilloscope is an integrated and powerful system providing the capability to:
Capture the key events with high resolution for longer time intervals
View data like never before, giving you more information more quickly, with a large,
color CRT and advanced display techniques
Analyze your signal to get answers quickly and more accurately with a powerful
processing system and math packages.
Eight trace display for a more complete picture.
9" Color Display
LeCroy provides a very large, sharp oscilloscope screen that is 50% larger
in total viewing area than a 7" screen.
Its powerful features include Analog Persistence, Color-Graded
Persistence, Full Screen mode, Opaque or Transparent display, color
association, and personal color schemes. These provide the user with
outstanding benefits that accelerate visual processing and effective
communication of on-screen information.
High-Speed Acquisition
The design and debug of fast digital systems and the need to capture fast
transient signals require high-speed signal capture. The LC574A four-
channel, 1 GS/s, 1 GHz bandwidth DSO operates at a 4 GS/s sample rate
for single-channel inputs. The high sample rate, bandwidth and the 1 GHz
trigger bandwidth provide a flexible solution for capturing and viewing
fast risetime signals.
Large Sample Rate Window
Having a high sample rate in a DSO is only the first step to preserving
data integrity. The time window over which this sample rate is available is
also of critical importance. Long acquisition memory maintains the

oscilloscope's highest sample rate for large time windows allowing the
user to sample long signals with high horizontal resolution.
With up to 8 million points of acquisition memory, the maximum sample
rate of the LC574AL of 4 GS/s (2 GS/s in LC334AL) is maintained for a
time window of 2 ms (4 ms in LC334AL). This sample rate window
enables the user to record long signals with high resolution.
Optimum Performance
SMARTMemory is a total memory management system that dynamically
allocates resources of microprocessor power, acquisition memory and
processing RAM. The intelligent management provided by SMARTMemory
guarantees optimal usage of oscilloscope resources.
The 96 MHz PowerPC microprocessor at the heart of these DSOs drives
the system to produce results fast, providing rapid waveform update and
super panel responsiveness.
Quick Diagnoses
Capturing and viewing waveforms are fundamental to an oscilloscope.
Productivity improvements are accessible by using built-in math functions
to assist troubleshooting and diagnoses of circuit problems.
The signal analysis capability of these DSOs is enhanced by advanced
waveform math, spectrum analysis, and waveform parameter analysis.
This analysis capability greatly increases the speed with which circuit
problems are clearly identified and solved.
Analog Persistence
At a push of the green button, the user can switch between an analog
style view and a digital view of signals on these oscilloscopes.
The depth of signal information can be explored along the third dimension
of the waveform display to give the user a complete picture of waveform
activity.
Unlike an analog oscilloscope, all signal data is captured and available in
memory for analysis and measurements. Analog Persistence gives the
user the best of both the analog and digital worlds of oscilloscopes.
Full Screen Grid
LeCroy DSOs not only have a very large 9" screen but also provide a
display mode with an extra-large grid, up to 150% larger than common
grid areas. In Full Screen mode, all of the screen area is used to display
signals. This provides a magnificent view of up to 8 waveforms: signal
details are seen more clearly and with greater ease.
8-Trace Display
An 8-trace display with any combination of math functions, zooms,
reference memories, or channels is a standard feature in the LC series.
Octal grid display is available in normal and Full Screen display modes,
with and without parameters displayed.
Easy Documentation
All waveform data and results of analysis can be quickly saved to floppy
disk, memory card, ATA flash card, or a removable hard disk. This
provides an efficient way to archive information and facilitates easy

documentation of results.
An internal graphics printer (standard in "L" models) outputs screen
dumps in seconds providing the user with an immediate and clear record
of signal activity.
