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 HL Introduction” introduces what the Seeker HL is and what it does.
This chapter discusses the practical application, connections and controls of the Seeker
HL. Finally, this chapter discusses the battery of the Seeker HL and how to update your
rmware.
• Chapter 3, “Seeker HL Operation” describes how to congure and operate the Seeker
HL.
• Chapter 4, “Leakage Testing” describes the steps needed to perform leakage testing
using the Seeker HL.
• Chapter 5, “Appendix” shows the technical specications of the Seeker HL as well as
any error codes that may appear on the display screen of the Seeker HL.
Optional Software
Although the Seeker HL comes precongured and ready to use from the factory, the following
software is required for advanced conguration of the Seeker HL:
• Seeker Setup is used to congure the Seeker HL, 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 VIAVI or
third-party applications.
Data acquired by the Seeker HL must be manually entered into LAW, as the Seeker HL
does not communicate directly to LAW.

Conventions Used in this Manual
This manual has several standardized conventions for presenting information:
• Connections, menus, menu options, and user-entered text and commands appear in
bold.
• Section names, web, and e-mail addresses appear in italics.
A NOTE is information that will be of assistance to you related
to the current step or procedure.
A CAUTION alerts you to any condition that could cause a
mechanical failure or potential loss of data.
A WARNING alerts you to any condition that could cause
personal injury.
Precautions
Do not use the Seeker HL in any manner not recommended
by the manufacturer.
A strong electromagnetic eld may affect the measurement
accuracy of the Seeker HL.
Use only the battery charger supplied with the Seeker HL.
All spent batteries should be disposed of according to local
laws and guidelines.

Introduction
What is the Seeker HL?
Overview
Mitigation of signal leakage within the subscriber premise is essential for
the successful operation of the subscriber’s cable and cellular services. To
thoroughly evaluate the potential for interference to subscriber services,
VIAVI has developed a patent pending approach to signal leakage
measurement which will comprehensively test the Aeronautical and LTE
bands in both fully digital and analog cable systems.
Historically, signal leakage detectors have required high levels of sensitivity
to measure signal leakage radiating from the CATV system. Measurement
within the subscriber premise and the migration to all digital services places
even greater sensitivity requirements upon the leakage detector combined
with a new requirement to simultaneously monitor for signal leakage in both
the aeronautical and LTE bands.
Chapter 2
In laboratory experiments signal leakage measurements as low as
0.1 uV/m have proven sufcient to allow LTE signals to enter the subscriber
network and disrupt cable services. Achieving a measurement sensitivity
of 0.1 uV/m is beyond the measurement range of conventional signal leakage detectors and
requires a new approach to leakage detection within the subscriber premise.
Testing with the Seeker HL Source Transmitter
To meet the new measurement and sensitivity requirements, the Seeker HL monitors 138
MHz and 757.5 MHz simultaneously, supporting testing in both the Aeronautical and LTE
frequency bands. The Seeker HL Source Transmitter replaces the cable service with two
high-output test carriers which pressurize the subscriber cabling, revealing any damage
which may lead to service interruption from ingressing LTE carriers.
The Seeker HL Source Transmitter has two output levels: a +60 dBmV for home
certication and a +40 dBmV output level should the subscriber network prove too porous
for pinpointing the location of a leak at the higher transmit level.
The displayed leakage levels are normalized by the Seeker HL receiver to reect the value
of the leak at nominal systems levels within the subscriber premise. The normalization
of the measured and displayed leakage levels simplies the evaluation of leakage
severity and provides consistency for documentation of leakage levels in accordance with
established industry practices.
Seeker HL User’s Guide
22130948, Rev. 003March 2019 Page 9
When utilizing the higher +60 dBmV transmit level the Seeker HL is able to locate signal
leakage down to a normalized leakage level of 0.1 uV/m with a single exible antenna;
making it possible to locate and repair signal leakage levels far beyond the measurement
range of conventional leakage detectors.
Seeker HL Features
Easy 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
settings.
For the sake of this manual, the term “low frequency” refers
to 138 MHz and “high frequency” refers to 757.5 MHz.

22130948, Rev. 003 March 2019Page 10
Squelch Operation
Squelch level is the RF signal threshold that the Seeker HL 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 5 µV/m. However, it can be recongured using
the Seeker Setup software.
Source Localization
The Seeker HL 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.
