PREFACE

About This Manual

The SignalOn Return Path Ampli er covered in this user manual is part of the SignalOn family of plug-in modules. The Return
Path Ampli er provides gain ampli cation with low distortion and low noise for a broadband communications system return

path (5 MHz to 200 MHz).

The SignalOn system uses a modular design that allows for high isolation combining, splitting, ampli cation, redundant

switching, and status monitoring of the headend signals in a broadband communications system. The SignalOn system

provides strong cable management, EMI shielding, and ease of use, all of which facilitate recon guration and enhance

performance within a dynamic headend environment.

Admonishments

Important safety admonishments are used throughout this manual to warn of possible hazards to persons or equipment.

An admonishment identi es a possible hazard and then explains what may happen if the hazard is not avoided. The

admonishments — in the form of Dangers, Warnings, and Cautions — must be followed at all times. These warnings are

fl agged by use of the triangular alert icon (seen below), and are listed in descending order of severity of injury or damage

and likelihood of occurrence.

Danger: Danger is used to indicate the presence of a hazard that will cause severe personal injury, death, or substantial
property damage if the hazard is not avoided.

Warning: Warning is used to indicate the presence of a hazard that can cause severe personal injury, death, or substantial
property damage if the hazard is not avoided.

Caution: Caution is used to indicate the presence of a hazard that will or can cause minor personal injury or property
damage if the hazard is not avoided.
