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 Trilithic
or third-party applications.
Data acquired by the Seeker D Lite must be manually entered into LAW, as the Seeker
D Lite does not communicate directly to LAW.

Introduction
What is the Seeker D Lite?
Overview
The new Seeker D Lite™ is a tough, convenient, and exible leakage
test tool. The Seeker D Lite works by measuring tagged RF signals in
and around a subscriber’s premises.
This leakage detector assists in installation and troubleshooting by
verifying that the leakage within the subscriber premises is not great
enough to contribute to the cable system’s cumulative leakage index
(CLI). Leaks can also be important indicators of ingress that can hinder
communication on the return band, as well as affecting downstream
QAM channels in the LTE band.
The Seeker D Lite works in conjunction with the CT-4™ Channel
Tagger in the headend or the Seeker D Lite Source Transmitter at
the ground block. Both devices provide an uncompromising tagging
solution for active analog or digital systems and can be used to identify
and locate all RF leaks in both the Aeronautical and LTE bands.
Chapter 2
Testing with the Seeker D Lite Source Transmitter
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 certication, 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.

Seeker D Lite Features
Easy Frequency 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
frequencies.
Multiple Frequency Presets
Your Seeker D Lite 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 dene 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
135–139 MHz (low band) and 610.5–615 MHz (high band) in 12.5 kHz increments.
While in monitoring mode, the Seeker D Lite can toggle
between both the low band and high band for dual-band
leakage detection.
For the sake of this manual, the term “low band” refers to the
frequencies of 135–139 MHz and “high band” refers to the
frequencies of 610.5–615 MHz.
Channel Tag Compatibility
Compatibility with the Trilithic CT-4 channel tag devices is another feature of your Seeker
D Lite. The CT-4 can act as a traditional CT-2™ or CT-3™, and can insert Trilithic’s
proprietary tagged signals in both the aeronautical range and the near LTE range at the
same time. The CT-4 eliminates the risk of affecting any adjacent digital channels by
injecting an adjustable signal from 10–30 dBmV, targeting approximately 30 dB below the
chosen digital carriers. Channel tag values in the meter are congured using the Seeker
Setup software.

Document Num., Rev. 4May 2018Page 10
Page 11
Squelch Operation
Squelch level is the RF signal threshold that the Seeker D Lite 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 20 µV/m. However, it can be recongured using
the Seeker Setup software.
Source Localization
The Seeker D Lite 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.

About the Battery of Your Seeker D Lite
The Seeker D Lite uses a Lithium-Ion battery. The battery is charged during manufacture and
should be ready to use as long as it has not been stored for a long period of time.
Lithium-Ion batteries operate differently than Nickel-Cadmium batteries. They should be
charged daily, and should not be deeply discharged, as this could damage the battery. There is
no memory effect, so there is no concern for frequent charging.
USB Charging
You can charge the Seeker D Lite using either of the following USB charging methods:
• Connecting the Mini-USB cable and charger from an AC power source to the Seeker
D Lite. The Mini-USB charge / data cable and charger must be connected to both the
Seeker D Lite and a working power outlet before AC charging can begin.
• Connecting the Mini-USB charge / data cable from a PC or laptop computer to the
Seeker D Lite. The Mini-USB charge / data cable must be connected to both the
Seeker D Lite and a PC or laptop computer that is ON before USB charging can
begin.
The following conditions apply when charging the Seeker D Lite via USB:
• When the Seeker D Lite is off and it is charging, the device will go into background
charging and nothing will be shown on the display screen.
• If the Seeker D Lite is on when it is connected to a to a PC, laptop computer, or
working power outlet, the device will automatically turn off.
• If the Seeker D Lite is turned back on when USB charging, the Measurement mode
is disabled while the Seeker D Lite is USB charging.
• When the Seeker D Lite is on and is charging, the screen shown in the image to the

RF Signal Measurement Mode
The RF Signal Measurement Mode is the default display mode for leakage testing and is
used to accurately determine the strength of a leak, pinpoint its location, and provide a
leakage value for documentation. Measured RF leakage values can range from 0.1 to 2000
µV/m and are displayed in large, easy-to-read numbers. A bar graph at the bottom of the
display illuminates proportionally to the signal strength of the leak.
Additionally, an audible tone will sound if the measured signal breaks squelch. The signal
breaks squelch when the RF leakage is greater than the squelch level and tag qualiers are
also met. This tone can be used to help locate the potential source of the leak.
When the Signal Level display is selected, the Antenna icon ashes as indicated by the red
circle in the following images.
When using a CT-4 installed in the headend, the measurement
range for in-home leakage is 20 to 2000 µV/m.
When using a Seeker D Lite Source Transmitter, the
measurement range for in-home leakage is 0.1 to 20 µV/m in

• When this display is selected, the following will occur:
1. The bar graph will indicate the speaker volume.
2. The numerical display will continue to display the RF
signal level.
• Press the CHANGE button repeatedly to increase the speaker
volume of the leakage tone. Brief presses increase the volume
to maximum and then it rolls over to the minimum volume.
After a few seconds in the Speaker Volume Level display
without any action by the user, the display will revert to the

Leakage Testing
Before You Begin Leakage Testing
• A low battery may cause the Seeker D Lite to NOT turn on. Try charging your battery for
3 hours to see if that xes the problem.
• The Seeker D Lite will retain the setup from when the meter was last shut off. For
example, if you were testing frequency preset number two and then turned off your
Seeker D Lite, when you turned it back on again the meter would automatically begin
testing that same preset.
Testing For Leaks
The CT-4 Digital Channel Tagger must be installed and set up
within the system before testing for leaks. The Seeker D Lite
Source Transmitter can also be used at the ground block.
The Seeker D Lite should be congured with the Seeker Setup software before beginning
leakage testing.
1. Turn on the SeekerD Lite
Press the red ON/OFF button until you hear 3 ascending tones. The Seeker D Lite will
power up in RF Level Measurement Mode.
2. Conrm the desired frequency preset (0–9) is selected
If using the Seeker D Lite for the rst time, the default frequency preset during
conguration with Seeker Setup software will be selected.
If the Seeker D Lite has been used since conguration with Seeker Setup software, the
last frequency used will be selected.
For more information about using the Preset Frequency
or Channel Tag features, see Chapter 3: Seeker Operation,
Display Modes.

3. Conrm the Seeker is in the RF Level Measurement mode
The Antenna icon on the display should be ashing for the RF Level Measurement
mode. If necessary, use the SELECT button to move to the Measurement mode (or let it
time out and return to Measurement mode automatically).
4. Begin leakage testing
Move the Seeker D Lite around the test area. If the detected leakage level exceeds the
squelch levels, the Seeker D Lite will alarm.
The frequency of the alarm tone will increase as the detected signal strength increases.
Continue to move the Seeker D Lite in the direction producing the highest tone
frequency to locate the source of the leak.
5. Cruise Mode
If an alarm is not detected in Measurement mode and you wish to continually monitor
leakage levels with your Seeker D Lite, you can select the Cruise mode to shutdown the
display and conserve the battery charge.
To select Cruise mode from the Measurement mode, press the red on/off button until 2
beeps are heard and CR is displayed.
If a signal greater than the squelch level is detected in Cruise mode, the Seeker D Lite
will beep to alert the user. Measurement mode can then be used to measure and nd
the leak.
6. Turn OFF the Seeker D Lite
When testing is complete, turn off the Seeker D Lite by holding down the red ON/OFF
button until you hear 3 descending tones.
The auto time out from the Measurement mode setting to
Cruise mode or off can be programmed via the Seeker Setup
software.
