Preface: About the Manual

xxii

Chapter 4, "Field Sweeping with the SDA-5000," begins with coverage of

test point compensation and how to configure your SDA-5000. 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 amplifier alignment.

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 well.

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 service centers

worldwide.
