Ab out this Manua l
Like the Waverunner scope itself, this manual is designed to make your measurements as ea sy as “1–2–3.” Each section show syoustep bystep howto usethe oscilloscop eto solve simple or complexproble m s .
Use the manual with Waverunner in front of you. Then you’ll see clearly just wha t is being referred to; and you can immediately put into action what is described.
The manual has two main parts: Part One, “G et t i ng St ar t ed,” is for new users and basic operations. It explains the most important
Wa verunner features, and shows you howto apply them. Use it when starting out and for getting quick results. Part Two, “ L ooki ng D eeper ,” goes into more detail. It explains how to perform complex measurements
using more advanced Wa verunner 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 howyour scope works.
Consult theglossa ry for clarification of oscillosco p eandrelatedterms. 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:

TAKE ADVANTAGE OF MAINTENAN CE AGREEMEN TS
W e offer a variety of services under the heading of Maintenance Agreeme nts. These give extended wa rranty and allow you to budget maintenance costs after the initial three-year w arranty has expired. Installation, training, enhancements, and on-site repairs — among other services — are available through special supplemental support agreements. Inquire at your L eCroy customer service center or national distributor.
OBTAIN ASSISTANCE
Help with installation, calib ration, and the use of your Wa verunne r scop ein a rang eof a p plications is a lso available from your customer service center.
RE T U RN A PRODUCT F OR SE RVICE OR RE PAIR
If you do need to return a L eCroy product, identify it by its model and serial numbers (see page 12). Describe the defect or failure, and provide your name and contact number.
Forfactoryreturns, use a Return AuthorizationNumber (RAN), obtainable from customer service. Attach it so that it can be clearly seen on the outside of the shipping package to ensure rapid forw arding within LeCroy.
Return those products requiring only maintenance to your customer service center.
Within the warranty period, transportation charges to the factory will be your responsibility , while products under warranty will be returned to you with transport prepaid by LeCroy . Outside the wa rranty period, you will ha veto provideus with a purch a seorde r nu mb e r before thew o rk can be done.

STAY UP-TO-DATE
To maintain you r Waverunner scope’s performance within specifications, have us calibrate it at least once a year. LeCroy offers state-of-the-art technology by continually refining and improving the instrument’s capabilities and operation. We frequently update both firmwa re and softwa re during service, free of charge during war r anty.

ScopeExploreris a highly practical PC-based connectivity tool that interfaces W ave runner to a PC that is
running MicrosoftWindows, via the rear panel GPIB (IE EE 488) or RS-232 port. Specia llydes ig n ed by LeCroy for its oscilloscopes, ScopeExplorer allows you to perform data and image transfers and other remote operations from scope to PC with just a few key board strokes or mouse clicks. See Chapter 12, “Use Waver unner wit h PC ,” for more about using ScopeExplorer w ith you r W ave runner scope.
S copeE xplorer now has a virtual front panel to allow full cont rol of remote scopes.
Activ eDSO w orks on any PC running Windows 95, 98 or NT, and enables you to exchange data with a variety of Window s applications or programming languages that support the ActiveX standard, such as MS
Office, Internet Explorer, Visual 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 OL E automation compatible client and use it manually without programming. You could, for example, generate a report by importing scope data straight
into E xcel or Word, analyze your wave forms by bringing them directly into MathCad, archive measurement results “on the fly” in a Microsoft Accessdatabase, and automatetests usingVisual Basic, Java,C++, or
Excel (VBA). Visit our websiteat http://www.lecroy.com/softwareto download these and other free softwa re applications.

OPERATE IN A SAFE ENVIRONMENT
Beforeinstallingyour Waverunner, ensurethat its ope rating environment will be maintained within these parameters:
Temperature: 5 to 40 °C (41 to 104 °F) Humidity: <80% RH (non-condensing) Altitude: <2000 m (6560 ft) Operation: Indoor use only
GET TO KNOW TH E WARNING SYM B O LS
Wherever these warning signs appear on the Waverunner’s front or rear pane ls, or in this manual, they alert you
to aspects of safety .

MAINTAIN POWER GROUND
Maintain the groundline to avo id electric shock .
The current-carrying conductors cannot exce ed 250 V rms with respect to ground potential. Wave runner is provided w ith a three-wire electrical cord containing a three-terminal polarized plug for line voltage and safety ground connection. The plug’ s ground terminal is connected directly to the frame of the unit. For adequa te protection against ele c trical haza rd,this plug must be inserted into a mating outlet containinga safety ground contact. Set the pow er switch to STANDBY before connecting or disconnecting the powe r cord.

RE PL ACE WITH THE CORRE CT FUSE S
For con tinued fire protection at all line voltages, repla cefuses only w ith those of the specified typ eand rating . Disconnect the powe r cord before inspecting or replacing a fuse. Open the fuse holder (located directly to the
left of the mains pow e r plug) using a small, flat-bladed screwdriver. Remove the old fuse and replace it w ith a ne w5x20 mm fuse(T 6.3 A/250 V).
CLEAN YOUR WAVERUNNER (BUT LET US MAINTAIN IT)
Maintenance and repairs should be carried out exclusively by a LeCroy technician. Clean only the exterior of your Waverunner, using a damp , soft cloth. Do not use chemicals or abrasive
ele m ents. Unde r no circumstance s allowmoisture to p e n etrate theoscilloscop e. To avoid elec tric shock s , disconnect the instrument from the pow er supply before cleaning .
