Putting Innovation Within Reach

Product innovation at Trilithic has always been characterized by one thing: it’s practical. It

makes life easier for customers. It’s the natural result of listening to them. That philosophy

has been the driving force behind the company’s growth from its beginnings as a two-man

engineering team in 1986 to its current position as a global manufacturer with more than 130

employees.

A privately held company, Trilithic broadend its original RF and microwave component product

line by acquiring lters manufacturer Cir-Q-Tel and instruments manufacturer Texscan, adding

broadband solutions to the product line. The company also expanded operations to Thailand in

2001, to meet increasing demand for its products in the growing markets of Asia.

As new communications applications continue to emerge, part of Trilithic’s business has

evolved into managing change—helping customers respond quickly to market opportunities

with innovative technology and individualized solutions. But the core value of Trilithic’s

business approach—listening to customers—hasn’t changed. Keeping that focus intact will

help provide better products in the long run and ensure continued growth for decades to come.

Trilithic is comprised of two major divisions:

Broadband Instruments

The company is best known for innovations in signal level measurement, leakage detection

and reverse path maintenance—like the use of Digital Signal Processing (DSP) technology,

which lets eld technicians upgrade their signal analyzers by simply downloading rmware.

Emergency Alert Systems

Trilithic’s EAS division is a leading supplier of homeland security government-mandated

emergency alert systems for broadband and other communication system providers. As

the communications industry continues its rapid evolution, Trilithic has begun offering

comprehensive systems and services to address a wide variety of emergency alert system

needs, including the design and architectural layout of complex analog and digital EAS

networks.

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.

Precautions

Periodic Calibration

The chosen frequency must closely match that of the leakage detector or leaks will not be

detected properly. If the Seeker HL Source Transmitter appears to be out of calibration, the unit

must be returned to Trilithic or a Trilithic authorized repair center for re-calibration.

A CAUTION alerts you to any condition that could cause a

mechanical failure or potential loss of data.

A NOTE is information that will be of assistance to you related

to the current step or procedure.

A WARNING alerts you to any condition that could cause

personal injury.

Do not use the Seeker HL Source Transmitter in any manner

not recommended by the manufacturer.

A strong electromagnetic eld may affect the measurement

accuracy of the Seeker HL Source Transmitter.

In-Home Leakage Evaluation System Introduction & Operation

Chapter 2

What is the Seeker HL Source Transmitter?

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, Trilithic 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.

In laboratory experiments signal leakage measurements as low as 0.1 uV/m have proven

sufcient 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 Approach

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

certication 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 reect the value

of the leak at nominal systems levels within the subscriber premise. The normalization

of the measured and displayed leakage levels simplies the evaluation of leakage

severity and provides consistency for documentation of leakage levels in accordance with

established industry practices.

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.

Equipment Supplied with the Seeker HL Source Transmitter
