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 D Lite 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 D Lite Source Transmitter in any
manner not recommended by the manufacturer.
A strong electromagnetic eld may affect the measurement
accuracy of the Seeker D Lite Source Transmitter.

Introduction & Operation
Chapter 2
What is the Seeker D Lite Source Transmitter?
Overview
Mitigation of signal leakage within the subscriber premise is essential for the successful
operation of services both inside and outside of the coaxial cable network. 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 network. Measurement within the
subscriber premise and the migration to all digital networks 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.
While these new requirements are a necessity to detect the potential for interference
between CATV and LTE services, the cost of designing, manufacturing and deploying this
new generation of leakage detectors has risen signicantly. As an industry leader in the
design and manufacture of signal leakage equipment, VIAVI has studied this application
model very carefully to develop a new and affordable method of signal leakage detection
within the subscriber’s premise.
Testing Approach
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.
