The figure on the preceding pag e shows the statistical analysis of a pulse-width-modulated signal displayed with
Analog Persistence . This is used to show the w ave form’s history . The histogram shows that there are nine
widths and that the frequency of occurrence of each pulse width varies proportional to the width. The next

JitterTrack display shows that the pulse widths increase seque ntially, from narrowe st to widest, with the

Introduction
Ab out this Manual
Like the Wa verunner-2 scopeitself, this manual is designed to make your mea surements as easy as “1–2–3.”
Each section shows you step by step howto use the oscilloscope to solve simple or complex problems.
Use the manual with the Wa verunner-2 in front of you. Then you’ll see clea rly just what is being referred to;
and you can immediately put into action what is described.
The manual has two main parts:
Part One, “G et ti ng S tart ed,” is for newusers and basic operations. It explains the most important
Wa verunner-2 features , and show s you howto apply them. Use it when starting out and for getting quick
results.
Part Two, “ L oo king D eeper,” goes into more detail. It explains how to perform complex measurements
using more advanced Wa verunner-2 functions. It also looks more deeply into operations covered in Part One.
Use it for tackling demanding tasks, or as a reference for understanding better how your scope w orks.
Consult theglossary for clarification of oscilloscope an d rela tedterms.
As an additional guide, each chapter is prefaced by a summary of its contents.
Wa tch for panels and sections throughout the manual marked by these icons:

RE T U RN A PRODUCT FOR SERVICE OR REPAIR
If you do need to return a LeCroy product, identify it by its model and
serial numbers (see page 25). Describe the defect or failure, and provide
your name and contact number.

Scope Explor eris a highly practical PC-based connectivity tool that interfaces Wave runner-2 to a PC that is
running Microsoft Windows, via there ar pa n e l GPIB (IEEE 488) or RS-232 port. Specia llydesig n ed by
LeCroy for its oscilloscope s, ScopeExplorer allows you to perform data and image transfers and other remote
operations from scopeto PC with just a fewkeyboard strokes or mouse clicks. See Chapter 12, “U se
Waverunner-2 with P C,” for more about using ScopeExplorer with your Wave runne r-2 scope .
S copeE xplorer now has a virtual front panel to allowfull control of remote scopes.
ActiveDSO works on any PC running Window s 95, 98 or NT, and enables you to exchangedata with a
variety of Windows applications or programming languages that support the ActiveX standard, such as MS
Office, Internet Explorer, Visua l Basic, Visual C++ and Visual Java. ActiveDSO hides the intricacies of
programming for each of these interfaces and provides a simple and consistent interface to the controlling
application. You can also visually embed ActiveDSO in any OLE automation compatible client and use it
manually without programming. You could, for examp le, generate a rep ort by importing scope data straight
into Excel or Word, analyze your wa veforms by bringing them directly into MathCad, archive measurement
results “on the fly” in a Microsoft Access database,and automatetests usingVisual Basic,Java, C++, or
Excel(VBA).

AC POWER SOURCE
The Wa verunner-2 operates from a single-phase
100–120 V (±10%) AC (~) power sou rce a t
50/60/400 (±10%) Hz, or 200–240 V (±10%) AC (~)
at 50/60 (±10%) Hz.
Maximum pow e r consumption: 250 VA (depe nding on
model)
No manual voltage selection is required because the
instru ment automaticallyadap ts to the line voltag e.
POWER AND GROUND CONNECTIONS
The Waverunner-2 is provided with a 3-wire electrical
cord containing a 3-terminal polarized plug for line
voltage and safety ground connection. The plug’s
groundterminalis connected directlyto the frameof
the Wa verunner-2. For adequa te protection against
electrical hazard, this plug must be inserted into a
mating outlet containing a safety ground contact.
Note: SetthepowerswitchtoSTANDBYbefore
connecting or disconnecting the pow e r cord.
ON /STANDBY SWITCH
The On/ Standby toggle switch controls the basic operational state of the DSO. A portion of the DSO will
remainpowered inthestandby state(5Watts dissipation).
