ABOUT THE MANUAL
Section I Introduction
Chapter 1 introduces you to the new SDA family of CATV test
equipment. In this chapter, you learn about the features and
capabilities of the SDA field and headend units, and about
the various options available.
Section II Field Units
Chapter 2, "Description and Basic Operation," describes the
SDA-5000’s user interface and its basic modes of operation.
You also learn basic configuration procedures and what you
need to print files and screen shots.
Chapter 3, "Channel Plans," shows you how to configure your
unit’s channel plan capability, edit channel plan
parameters, create, copy and edit channel
plans, and how to configure a digital carrier.
Chapter 4, "Field Sweeping with the SDA-5000
," begins with
coverage of test point compensation and how to configure
. Sweep configuration is covered in detail,
after which you learn how to connect to amplifier test
points and how to conduct forward, reverse, sweepless, and
loopback sweeps. This chapter also describes reverse
Chapter 5, "Reverse Path Troubleshooting," describes the
problems most common to the return path, offers tips to help
you more quickly trace the trouble, and shows you how to use
the Zero Span mode to look at TDMA signals.
Chapter 6, "Measuring System Performance," explains how to
evaluate system performance by measuring key parameters.
Operations covered include Level, Tilt, Scan,
Carrier-to-Noise ratio (C/N), Hum, Modulation-Demodulation,
Composite Second Order (CSO) and Composite Triple Beat (CTB).
Chapter 7, "Spectrum Analyzer Mode," describes the
SDA-5000’s spectrum analysis capabilities and how it can
assist you in general troubleshooting and in examining TDMA
signals with the Zero Span mode. CSO/CTB mode is covered as
Chapter 8, "PathTrak Field View (OPT3)," shows you how to
use PathTrak mode for return path troubleshooting by
comparing spectrum measurements at the node with current
conditions at the headend.
Chapter 9, "Digital Analysis (QAM View OPT4)," explains how
to use the new QAM digital channel tool. You’ll learn to
measure the most critical characteristics of a digital
channel, and how to use a spectrum view of ingress. You’ll
also learn how to use the constellation view to assist you
in your troubleshooting efforts and how to use the equalizer
to correct the effects of reflections in the transmission path.
Chapter 10, "Automatic Test," explains how to perform
automatic system tests, an easy way to acquire
proof-of-performance compliance data. You learn how to
create test locations and how to edit location parameters,
as well as how to set testing schedules and how to view and
print test reports.
Chapter 11, "Files," describes how to store, view, or print
files created from field measurement data. Sweep reference
files and measurement files are covered, along with the
procedure for comparing a reference file with a "live"
sweep in the field.
Chapter 12, "Maintenance," covers the routine maintenance
tasks that a service technician can perform in the field.
Inspection, connector replacement, battery terminal
cleaning, general cleaning, and calibration are all covered.
The chapter ends with a list of Acterna
Section III Headend Units
Chapter 13, "Description and Basic Operation of the SDA-5500
," describes the user interface and basic modes
of operation for the SDA headend units (SDA-5500
SDA-5510). You also learn basic configuration procedures and
what you need to print files and screen shots.
Chapter 14, "SDA-5500/SDA-5510
Sweep Configuration," shows
you how to configure the SDA-5500
for forward sweep and for
reverse sweep. It covers wiring connections, telemetry and
frequency settings, channel plan creation and editing, and
how to test the transmitter setup. You’ll also find
important information about using the SDA-5500
together. In addition, this chapter includes a section on
sweep history and theory that will deepen your understanding
of what sweeping is and how it works.
Section IV Appendices
Appendix A, "Application Notes," contains the full text of
four application notes that help to clarify many of the
issues covered in other chapters in the manual. The four
application notes are: "Forward Sweep and Balance,"
"Reverse Sweep and Balance," "Return Path Troubleshooting,"
and "Proofing and Testing."
Appendix B, "Specifications," lists the technical
specifications for each unit.
Appendix C, "Status Indicators and Icons," provides a
descriptive list of indicators and icons that you’ll find on
the SDA’s screens and used throughout the manual.
Appendix D, "User and Error Messages," describes many of the
messages that appear on-screen indicating a problem in
operation or a malfunctioning unit.
The Glossary defines many of the terms used throughout the
