While using this product, you may need to access other parts of the system. Read the General Safety Summary in other system manuals for warnings and cautions related to operating the system.

To Avoid Fire or Personal Injury

Use Proper Power Cord. Use only the power cord specified for this product and

certified for the country of use. Power cord needed only in the mainframe, not modules.

Connect and Disconnect Properly . Do not connect or disconnect probes or test leads while they are connected to a voltage source.

Ground the Product. The mainframe is grounded through the grounding conductor of the power cord. To avoid electric shock, the grounding conductor must be connected to earth ground. Before making connections to the input or output terminals of the product, ensure that the product is properly grounded.

Ground the Product. The modules are indirectly grounded through the grounding conductor of the mainframe power cord. To avoid electric shock, the grounding conductor must be connected to earth ground. Before making connections to the input or output terminals of the product, ensure that the product is properly grounded.

Observe All Terminal Ratings. To avoid fire or shock hazard, observe all ratings and markings on the product. Consult the product manual for further ratings information before making connections to the product.

Do not apply a potential to any terminal, including the common terminal, that exceeds the maximum rating of that terminal.

Do Not Operate Without Covers. Do not operate this product with covers or panels removed.

Use Proper Fuse. Use only the fuse type and rating specified for this product. Avoid Exposed Circuitry. Do not touch exposed connections and components

when power is present. Wear Eye Protection. Wear eye protection if exposure to high-intensity rays or

laser radiation exists. Do Not Operate With Suspected Failures. If you suspect there is damage to this

product, have it inspected by qualified service personnel.

Preface

Manual Structure

Manual Conventions

This is the service manual for the CSA8000 Communications Signal Analyzer, TDS8000 Digital Sampling Oscilloscope and the sampling and other modules that install in both instruments. Read this preface to learn how this manual is structured, what conventions it uses, and where you can find other information related to servicing this product. Read the Introduction following this preface for safety and other important background information needed before using this manual for servicing this product.

This manual is divided into chapters, which are made up of related subordinate topics. These topics can be cross referenced as sections.

Be sure to read the introductions to all procedures. These introductions provide important information needed to do the service correctly, safely, and efficiently.

Replaceable Parts

Safety

This manual uses certain conventions that you should become familiar with before attempting service.

Throughout this manual, the term module appears. A module is composed of electrical and mechanical assemblies, circuit cards, interconnecting cables, and a user-accessible front panel. “Sampling modules,” such as electrical sampling and optical sampling modules, refer to products.

This manual refers to any field-replaceable assembly or mechanical part specifically by its name or generically as a replaceable part. In general, a replaceable part is any circuit board or assembly, such as the hard disk drive, or a mechanical part, such as the I/O port connectors, that is listed in the replaceable parts list of Chapter 10.

Symbols and terms related to safety appear in the Service Safety Summary found at the beginning of this manual.

System Specifications

This section contains the specifications for the CSA8000 Communications Signal Analyzer, tions are guaranteed unless noted as “typical.” Typical specifications are provided for your convenience but are not guaranteed. Specifications that are marked with the n symbol are checked in Performance Verification chapter of the service manual, an optional accessory.

All specifications apply to the instrument and sampling modules. unless noted otherwise. To meet specifications, three conditions must first be met:

H The instrument must have been calibrated/adjusted at an ambient tempera-

ture between +20_ C and +30_ C. H The instrument must have been operating continuously for 20 minutes within

the operating temperature range specified. H The instrument must be in an environment with temperature, altitude,

humidity, and vibration with the operating limits described in these

specifications.

Trigger sources External Direct Edge Trigger, External Precsaled Trigger, Internal Clock

Trigger, and Clock Recovery (with appropriately equipped optical modules)

Auto/normal mode Normal mode: wait for trigger

Auto mode: Trigger automatically generated after 100 ms time-out

Slope + or – select Edge + mode: Triggers on positive-slewing edge

Edge – mode: Triggers on negative-slewing edge

High frequency on/off select

High Frequency ON mode: Removes trigger hysteresis and improves sensitivity. Should be used when trigger slew rate exceeds 1 V/ns.

High Frequency OFF mode: Retains trigger hysteresis and improves noise rejection at low slew rates.

Metastability Reject On/Off select

Metastability Reject On mode: Upon detection of trigger and holdoff collision, time base will reject the sampled point.

Metastability Reject Off mode: Allows metastable points caused by trigger/holdoff collisions to display.

Variable trigger hold off range and resolution
