How this Manual is Organized

This manual is divided into the following chapters:

• Chapter 1, “General Information” provides contact information and describes how this

operation manual is structured.

• Chapter 2, “Seeker D Lite Introduction” introduces what the Seeker D Lite is and what it

does. This chapter discusses the practical application, connections and controls of the

Seeker D Lite. Finally, this chapter discusses the battery of the Seeker D Lite and how

to update your rmware.

• Chapter 3, “Seeker D Lite Operation” describes how to congure and operate the

Seeker D Lite.

• Chapter 4, “Leakage Testing” describes the steps needed to perform leakage testing

using the Seeker D Lite.

• Chapter 5, “Appendix” shows the technical specications of the Seeker D Lite as well as

any error codes that may appear on the display screen of the Seeker D Lite.

Optional Software

Although the Seeker D Lite comes precongured and ready to use from the factory, the

following software is required for advanced conguration of the Seeker D Lite:

• Seeker Setup is used to congure the Seeker D Lite, enabling the operator to assemble

les containing channel frequencies, squelch levels, and other settings. Users can

efciently download congurations to one or more leakage detectors.

• Leakage Analysis Workshop (LAW) is software that manages the storage and

retrieval of leakage information collected by vehicle mounted Seeker GPS systems.

Installed on a server, it receives leakage data uploads via the Internet/LAN, Wi-Fi

access point, or cellular connection. Data stored in LAW server may be displayed on

maps or as text, used to generate leakage work orders, or downloaded to other Trilithic

or third-party applications.

Data acquired by the Seeker D Lite must be manually entered into LAW, as the Seeker

D Lite does not communicate directly to LAW.

Introduction

Chapter 2

What is the Seeker D Lite?

Overview

The new Seeker D Lite™ is a tough, convenient, and exible leakage

test tool. The Seeker D Lite works by measuring tagged RF signals in

and around a subscriber’s premises.

This leakage detector assists in installation and troubleshooting by

verifying that the leakage within the subscriber premises is not great

enough to contribute to the cable system’s cumulative leakage index

(CLI). Leaks can also be important indicators of ingress that can hinder

communication on the return band, as well as affecting downstream

QAM channels in the LTE band.

The Seeker D Lite works in conjunction with the CT-4™ Channel

Tagger in the headend or the Seeker D Lite Source Transmitter at

the ground block. Both devices provide an uncompromising tagging

solution for active analog or digital systems and can be used to identify

and locate all RF leaks in both the Aeronautical and LTE bands.

Testing with the Seeker D Lite Source Transmitter

To overcome the high design and manufacturing cost associated with improvements in

instrument sensitivity, this system uses the Seeker D Lite Source Transmitter high output

signal source to replace the cable service at the subscriber’s ground block. The higher

levels transmitted by the Seeker D Lite Source Transmitter will increase the eld strength of

the signals radiating out of the subscriber network allowing a lower cost receiver to be used

for measurement purposes.

The Seeker D Lite Source Transmitter injects two carriers into the subscriber network, one

at 135–139 MHz and another at 611–615 MHz, supporting testing in both the Aeronautical

and LTE bands. The user may set the output level to 43 dBmV for home certication, but

also has the option to reduce the level to 23 dBmV should the subscriber network prove to

be too porous for pinpointing the location of a leak at the higher transmit level.

The Seeker D Lite provides both a visual readout of the measured levels in uV/m and a

tone proportional to signal strength. To prevent false triggering this system utilizes Trilithic’s

channel tagging technique. To provide constancy with leakage levels typically found within

the subscriber’s premise in home cert mode, the levels displayed by the Seeker D Lite have

been normalized to represent the value of a leak at typical system levels. This correlation

between measured and displayed levels will assist the technician in evaluating the severity

and recording of a leak based upon established industry practices.

Seeker D Lite User's Guide

Document Num., Rev. 4 May 2018Page 10

While in monitoring mode, the Seeker D Lite can toggle

between both the low band and high band for dual-band

leakage detection.

For the sake of this manual, the term “low band” refers to the

frequencies of 135–139 MHz and “high band” refers to the

frequencies of 610.5–615 MHz.

Seeker D Lite Features

Easy Frequency Configuration

The Seeker Setup software simplies the conguration process. Instead of going to the

factory to make hardware modications, you can use the Seeker Setup software to adjust

frequencies.

Multiple Frequency Presets

Your Seeker D Lite can be setup to operate on up to 10 different frequency presets, which

makes it easier to monitor and maintain multiple cable systems. These presets dene the

leakage monitoring frequency and, if desired, the tag detection frequency as well. You have

the option of setting up only one frequency preset for simple operation, or multiple leakage

frequencies for maintaining multiple cable systems. Frequency settings range from

135–139 MHz (low band) and 610.5–615 MHz (high band) in 12.5 kHz increments.

Channel Tag Compatibility

Compatibility with the Trilithic CT-4 channel tag devices is another feature of your Seeker

D Lite. The CT-4 can act as a traditional CT-2™ or CT-3™, and can insert Trilithic’s

proprietary tagged signals in both the aeronautical range and the near LTE range at the

same time. The CT-4 eliminates the risk of affecting any adjacent digital channels by

injecting an adjustable signal from 10–30 dBmV, targeting approximately 30 dB below the

chosen digital carriers. Channel tag values in the meter are congured using the Seeker

Setup software.
