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 VIAVI or an 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.

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, 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.
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 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
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.

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.
