IMPORTANT NOTICE TO THE USERThis manual contains information for servicing the YOKOGAWA Digital Scope DL708E.Check the serial number to confirm that this Service Manual covers the right instrument.Make sure to use the wrong manual.

Before any maintenance and servicing, read all safety precautions carefully.

Only properly trained personnel may carry out maintenance and servicing inaccordance with and to the extent permitted by this Service Manual.

Do not disassemble the instrument or its parts, unless otherwise clearly permitted bythis Service Manual.

Do not replace any part or assembly, unless otherwise clearly permitted by thisService Manual.

YOKOGAWA ELECTRIC CORPORATION (YOKOGAWA) does not in principle supplyparts other than those listed in the Customer Maintenance Parts List in this ServiceManual (mainly modules and assemblies). Therefore if an assembly fails, the user

should replace the whole assembly and NOT components within the assembly (seeNOTE). If the user attempts to repair the instrument by replacing individual componentswithin the assembly, YOKOGAWA assumes no responsibility for any consequences,

such as defects in instrument accuracy, functionality, or reliability, or user safety hazards.

YOKOGAWA does not offer more detailed maintenance and service information than thatcontained in this Service Manual.

All reasonable efforts have been made to assure the accuracy of the content of thisService Manual. However, there may still be errors such as clerical errors or omissions.

YOKOGAWA assumes no responsibility of any kind concerning the accuracy or contentsof this Service Manual, nor for the consequences of any errors.

All rights reserved. No part of this Service Manual may be reproduced in any form or byany means without the express written prior permission of YOKOGAWA. The contents ofthis manual are subject to change without notice.

NoteYOKOGAWA instruments have been designed in a way that the replacement of electronic partscan be done on an assembly (module) basis by the user. YOKOGAWA instruments have alsobeen designed in a way that troubleshooting and replacement of any faulty assembly can bedone easily and quickly. Therefore, YOKOGAWA strongly recommends replacing the entireassembly over replacing parts or components within the assembly. The reasons are as follows:• The instruments use high-performance microprocessors, large scale CMOS gate arrays and

surface-mount components to provide state-of-art performance and functions.• Repair of components can only be performed by specially trained and qualified maintenance

personnel with special tools. In addition, repair of components requires various special partsand components, including costly ones. It also requires facilities where highly-accurate andexpensive maintenance equipment and special tools are provided.

• When taking the service life and cost of the instruments into consideration, the replacement ofassemblies offers the user the possibility to use YOKOGAWA instruments more effectivelyand economically with a minimum in downtime.

INTRODUCTIONThis manual contains information for servicing the YOKOGAWA Digital Scope DL708E.

NoteThis manual is the first edition, September 1998.

WARNINGThis Service Manual is to be used by properly trained personnel only. To avoidpersonal injury, do not perform any servicing unless you are qualified to do so.

Refer to the Safety Precautions prior to performing any service.Even in case of servicing according to this Service Manual and carried out byqualified personnel, YOKOGAWA assumes no responsibility for any result

occurring from this servicing.

SAFETY PRECAUTIONSThe following general safety precautions must be observed during all phases of

operation, service, and repair of this instrument. Failure to comply with theseprecautions or with specific WARNINGS given elsewhere in this manual violates safetystandards of design, manufacture, and intended use of the instrument.

YOKOGAWA ELECTRIC CORPORATION assumes no liability for the customer’s failureto comply with these requirements.

General definitions of safety symbols used on equipment and in manuals.

Affixed to the instrument. Indicates danger to personnel orinstrument and the operator must refer to the User's Manual. Thesymbol is used in the User's Manual to indicate the reference.

Functional earth terminal (This terminal should not be used as a“Protective earth terminal”.)

WARNING Describes precautions that should be observed to prevent seriousinjury or death to the user.

CAUTION Describes precautions that should be observed to prevent minor or

moderate injury, or damage to the instrument.

SM 701820-01E 3

WARNINGPower SupplyEnsure the source voltage matches the voltage of the power supply beforeturning ON the power.

Power Cord and PlugTo prevent an electric shock or fire, be sure to use the power cord supplied by

YOKOGAWA. The main power plug must be plugged in an outlet with protectiveearth terminal. Do not invalidate protection by using an extension cord withoutprotective grounding.

Protective GroundingThe protective earth terminal must be connected to ground to prevent an electric

shock before turning ON the power.

Necessity of Protective GroundingNever cut off the internal or external protective earth wire or disconnect thewiring of protective earth terminal. Doing so poses a potential shock hazard.

Defect of Protective Earth and FuseDo not operate the instrument when protective earth or fuse might be defective.

Do not Operate in an Explosive AtmosphereDo not operate the instrument in the presence of flammable liquids or vapors.Operation of any electrical instrument in such an environment constitutes a

safety hazard.

Do not Remove any CoversThere are some areas with high voltages. Do not remove any cover if the powersupply is connected. The cover should be removed by qualified personnel only.

External ConnectionTo ground securely, connect the protective grounding before connecting tomeasurement or control unit. Also, when touching the circuit, turn off the power

to the circuit and check that there is no voltage being generated.

[[Initialization]Before performing this test, initialize the settings. (Press the SETUP key and select the“Initialize” option.)

[Procedure](1) Connect the measurement leads according to connection diagram 1, and set the

Resistance to 120 Ω.(2) Set the excitation voltage to Excitation 2 V, and measure the bridge voltage

(Excitation) with a digital multimeter.(3) Calculate the Scaling factor (SF2) when the excitation voltage is set to Excitation 2 V.

(SF2 = Digital multimeter’s measurement value ÷ 2.0000)

(4) Connect the measurement leads according to connection diagram 1, and set theResistance to 350 Ω.

(5) Set the excitation voltage to Excitation 5 V, and measure the bridge voltage

(Excitation) with a digital multimeter.(6) Calculate the Scaling factor (SF5) when the excitation voltage is set to Excitation 5 V.

(SF5 = Digital multimeter’s measurement value ÷ 5.0000)

(7) Connect the output cable of the digital voltage generator to the channel to be testedas shown connection diagram 2.

4.4 Functions of Each Gate Array

4.4 Functions of Each Gate ArrayAcquisition Data Processor Gate Array (ADP)

This is a CMOS gate array which aims to process the data from the A/D converters sothat the data can be written to the acquisition memories. One ADP gate array supports 4

channels. It also performs triggering, average, box-average and envelope functionprocessing.

Acquisition Control Logic Gate Array (ACL)This is a CMOS gate array which aims to generate and control memory addresses to beused for Acquisition, P-P compression, Histogram, Average processing and the accessby CPU. It also controls CPU, peripheral devices and the keyboard.

Graphic Control Gate Array (GCG)This is a CMOS gate array which performs the general graphic control as follows:• This enables the CPU to perform read/write control of VRAM for graphics and SRAM

for text.• To supplement rasters• To interpret commands for the waveform display area

5.1 IntroductionThis chapter describes troubleshooting items to solve presumable errors. In such cases,

assembly removal may be required. Please heed the following warning.

WARNINGReplacing assembly must be performed only by qualified service personnel who

are aware of the hazard involved (such as fire and electrical shock).

NoteIf an error message is displayed, the error may have been caused by incorrect operation of theunit. Check the User’s Manual, and perform the correct operation.

(1)’A short-circuit may occur in an assembly other than the power supply unit. To check inwhich voltage line a short circuit has occurred, investigate each assembly to whichvoltage is supplied, using a circuit test. The table below shows the relationship between

assemblies and voltage supplied to them.
