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 congure 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 specications 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 precongured and ready to use from the factory, the
following software is required for advanced conguration of the Seeker D Lite:
• Seeker Setup is used to congure the Seeker D Lite, enabling the operator to assemble
les containing channel frequencies, squelch levels, and other settings. Users can
efciently download congurations 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
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.
Chapter 2
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 certication, 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 Features
Easy Frequency Configuration
The Seeker Setup software simplies the conguration process. Instead of going to the
factory to make hardware modications, 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 dene 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.
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.
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 congured using the Seeker
Setup software.

Squelch Operation
Squelch level is the RF signal threshold that the Seeker D Lite uses to determine the
validity of the signal. The signal “breaks squelch” when the RF leakage is greater than
the squelch level and tag qualiers are met as well. The receiver will not alarm for signals
below the squelch level.
The squelch level has a factory default of 20 µV/m. However, it can be recongured using
the Seeker Setup software.
Source Localization
The Seeker D Lite emits an audible tone to help you pinpoint the leakage source. The tone
frequency increases proportional to signal strength. As you move closer to the leak, the
frequency of the tone will increase.
Common leakage areas are around the tap, drop cable,
ground block, CPE, and any connection of the cable to other
devices.
