How this Manual is Organized
This manual is divided into the following chapters:
• Chapter 1, “General Information” provides Trilithic contact information and describes how
this Operation Manual is structured.
• Chapter 2, “Introduction” describes the Seeker Lite² and its features. This chapter also
discusses the connections and controls of the Seeker Lite². Finally, this chapter discusses
the Seeker Lite²’s battery and how to update your firmware.
• Chapter 3, “Operation” describes how to configure and operate the Seeker Lite².

Precautions
WARNING: Do not use the Seeker Lite² in any manner not
recommended by the manufacturer.
CAUTION: A strong electromagnetic field may affect the accuracy of
Seeker Lite²’s measurements.
CAUTION: Use only the battery charger supplied with the Seeker Lite².
Optional Software
Although the Seeker Lite² comes preconfigured and ready to use from the factory, the Seeker
Setup software is required for advanced configuration of the Seeker Lite². This software enables
the operator to assemble files containing channel frequencies, squelch levels, and other settings.
Users can efficiently download configurations to one or more leakage detectors.

What is the Seeker Lite²?
Seeker Lite² is a tough, convenient and flexible tool used to perform leakage tests. It can assist in
subscriber installs by verifying that leakage in the house is not great enough to contribute to the
cable system’s Cumulative Leakage Index (CLI). It can also be used to find leaks during
troubleshooting.
Seeker Lite² works by measuring ambient RF leakage in and around a subscriber’s premises
and can be used to identify and locate all RF leaks greater than 10 μV/m.
Note: The Seeker Lite² is not made for use with an external dipole
antenna. It is calibrated only with the built-in antenna.
Seeker Lite² Features
Easy Frequency Configuration
The Seeker Setup software simplifies the configuration process. Instead of going to the
factory to make hardware modifications, you can use the Seeker Setup software to adjust
frequencies.

Multiple Frequency Presets
Your Seeker Lite² 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 define 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
118.50 MHz to 147.2500 MHz in 6.25 kHz increments (these increments are sufficient for use
with HRC).
Note: Your Seeker Lite² monitors one frequency at a time. It does not
scan several frequencies at once.
Superior Antenna
An improved antenna design provides more directionality than typically available from other
leakage meters.
Channel Tag Compatibility
Compatibility with both the Trilithic CT-2 and CT-3 channel tag devices is another feature of
your Seeker Lite². Channel Tag refers to the process of adding frequency tags to a broadcast
channel signal. Your Seeker Lite² can be setup to detect a tagged leak and to ignore leaks
that are not tagged. With this feature, you are saved from chasing false alarms from signals
that do not originate in your system.
Channel Tag values range between 10 Hz and 23 Hz and are configured using the Seeker
Setup software.
GT Noise Discrimination
Your Seeker Lite² works with systems employing digital set top terminals that cannot tolerate
“tagged” leakage carriers. Therefore, enhanced “false alarm” resistance can be provided
without the use of a tagged leakage signal. The Seeker Lite² analyzes the detected RF energy
and automatically rejects all noise and signals that are not caused by leaks from your system.
GT noise discrimination is enabled/disabled using the Seeker Setup software.

Squelch Operation
Squelch level is the RF signal threshold that the Seeker Lite² uses to determine the validity of
the signal. The signal “breaks squelch” when the RF leakage is greater than the squelch level,
as long as any enabled tag or GT noise qualifiers 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 reconfigured using
Seeker Setup software.
Source Localization
The Seeker Lite² emits an audible tone to help you pinpoint the leakage source. The tone
frequency increases with signal strength. As you move closer to the leak, the tone frequency
will increase.
Note: Common leakage areas are around the tap, drop cable and any
connection of the cable to other devices.
