• Chapter 5, “Appendix” shows the technical specications of the Seeker HL as well as
any error codes that may appear on the display screen of the Seeker HL.
Optional Software
Although the Seeker HL comes precongured and ready to use from the factory, the following
software is required for advanced conguration of the Seeker HL:
• Seeker Setup is used to congure the Seeker HL, enabling the operator to assemble
les containing channel frequencies, squelch levels, and other settings. Users can
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 VIAVI or
third-party applications.
Data acquired by the Seeker HL must be manually entered into LAW, as the Seeker HL
does not communicate directly to LAW.

Introduction
What is the Seeker HL?
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.
Chapter 2
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 with the Seeker HL Source Transmitter
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.
Seeker HL User’s Guide
22130948, Rev. 003March 2019 Page 9
Page 10
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.
Seeker HL Features
Easy 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
settings.
For the sake of this manual, the term “low frequency” refers
to 138 MHz and “high frequency” refers to 757.5 MHz.
Seeker HL User’s Guide
22130948, Rev. 003 March 2019Page 10
Page 11
Squelch Operation
Squelch level is the RF signal threshold that the Seeker HL 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 5 µV/m. However, it can be recongured using
the Seeker Setup software.
Source Localization
The Seeker HL 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 HL
The Seeker HL 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 HL using either of the following USB charging methods:
• Connecting the Mini-USB cable and charger from an AC power source to the Seeker
HL. The Mini-USB charge / data cable and charger must be connected to both the
Seeker HL 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 HL. The Mini-USB charge / data cable must be connected to both the Seeker
HL and a PC or laptop computer that is ON before USB charging can begin.
The following conditions apply when charging the Seeker HL via USB:
• When the Seeker HL 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 HL 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 HL is turned back on when USB charging, the Measurement mode is
disabled while the Seeker HL is USB charging.
• When the Seeker HL is on and is charging, the screen shown in the image to the
right will be displayed, the Charge icon will ash, and the on-screen bar graph will
show the charging progress.

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 1000
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 source of the leak and, perhaps more
importantly, the potential source of ingress.
The image displayed to the right represents the leakage detector
measurement mode with no signal detected. Notice how no
values are displayed and the bar graph at the bottom of the
screen remains blank.
Within the leakage detector measurement mode, the antenna
icon in the lower right side of the screen ashes to indicate that
the leakage detector is currently taking measurements.
No Signal Detected
The image displayed to the right indicates detected leakage
values of 174 uV/m at 757.5 MHz and 23 uV/m at 138 MHz. The
bar graph at the bottom of the screen will display the relative
signal level of the detected signal.
Additionally, when the show noise setting is turned off, the tag
icon will be displayed in the upper right corner of the display to
indicated that the leakage detector is receiving the tagged signal
from the Seeker HL Source Transmitter.
If the tag icon is not displayed along with the signal level, the
show noise setting is turned on. In this mode, the signal levels
that are displayed will also include non-tagged noise that is
received by the leakage detector.

Offset Level Settings
The image displayed to the right shows the offset levels for both the
high and low frequencies. These values are used to normalize the
leakage readings to typical system levels.
Example: If the transmitter is injecting 60 dBmV at the ground block
and typical system level is 0 dBmV, with a 60 dB offset, the leakage
readings will reect what the leakage values would be as if the launch
level at the house were 0 dBmV.
If the “Enable Meter Entry” checkbox is checked within the Seeker
Setup software during conguration, these levels are adjustable on the leakage detector.
We recommend to uncheck this setting so that these values are not visible on the leakage
detector and can only be adjusted in Seeker Setup.
Press the SELECT button (middle right) once to view the offset level settings. The rst digit
of the high-frequency offset levels will begin to ash. To adjust the value of the selected digit
upward, press the CHANGE button (upper right).
Press the SELECT button (middle right) again to move the selection to the next digit and
continue this process until you are nished entering the offset values. The offset value for both
the high and low frequencies can be set anywhere from 20 to 80 dB.
Input Level Settings
The image displayed to the right shows the input level setting that
should match the transmit level of the Seeker HL Source Transmitter.
The source transmitter operates at two different output levels of
60 dBmV (120 dBuV) and 40 dBmV (100 dBuV), as indicated on the
label on the back of the device.
Example: If the output level of the transmitter is set to 60 dBmV
(120 dBuV), the input level of the leakage detector should be set to
120 dBuV.
Within the input level setting mode, the PK icon in the upper middle side of the screen ashes.
If the “Enable Meter Entry” checkbox is checked within the Seeker Setup software during
conguration, this level is adjustable on the leakage detector.
Press the SELECT button (middle right) ve times to view the input level setting. The input
level setting will begin to ash. To adjust the value of the input level, press the CHANGE button
(upper right). The input level value can be set to 120 dBuV or 100 dBuV.

continuously displayed as indicated in
the following image.
• 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 VOLUME button again 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
Signal Level display.
The speaker volume does not change during adjustment, but
is instead indicated by the bar graph. When leaks are found,
you will hear the volume change in the leakage tone.

Leakage Testing
Before You Begin Leakage Testing
• A low battery may cause the Seeker HL to NOT turn on. Try charging your battery for 3
hours to see if that xes the problem.
• The Seeker HL will retain the setup from when the meter was last shut off. For example,
if you were testing with the distance set to the near-eld probe setting and then turned
off your Seeker HL, when you turned it back on again the meter would automatically
begin testing that same distance.
Testing For Leaks
The Seeker HL and Seeker HL Source Transmitter should be congured with the Seeker Setup
software before beginning leakage testing.
1. Turn on the Seeker HL
Press the red ON/OFF button until you hear 3 ascending tones. The Seeker HL will
power up in RF Level Measurement Mode.
2. 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).
If the “Enable Meter Entry” checkbox is checked within the
Seeker Setup software during conguration, the following
levels are adjustable on the leakage detector.
If this checkbox is unchecked, these settings cannot be
adjusted on the meter. Skip to Step 5.
3. Conrm the desired offset levels are selected
These values are used to normalize the leakage readings to typical system levels.
Press the SELECT button (middle right) once to view the offset level settings. The rst
digit of the high-frequency offset levels will begin to ash. To adjust the value of the
selected digit upward, press the CHANGE button (upper right).
Press the SELECT button (middle right) again to move the selection to the next digit
and continue this process until you are nished entering the offset values. The offset
value for both the high and low frequencies can be set anywhere from 20 to 60 dB.

4. Conrm the desired input level settings are selected
The input level setting should match the transmit level of the Seeker HL Source
Transmitter. The source transmitter operates at two different output levels of 60 dBmV
(120 dBuV) and 40 dBmV (100 dBuV), as indicated on the label on the back of the
device.
Press the Select button (middle right) ve times to view the input level setting. The input
level setting will begin to ash. To adjust the value of the input level, press the CHANGE
button (upper right). The input level value can be set to 120 dBuV or 100 dBuV.
5. Begin leakage testing
Move the Seeker HL around the test area. If the detected leakage level exceeds the
squelch levels, the Seeker HL will alarm.
The frequency of the alarm tone will increase as the detected signal strength increases.
Continue to move the Seeker HL in the direction producing the highest tone frequency
to locate the source of the leak.
6. Turn OFF the Seeker HL
When testing is complete, turn off the Seeker HL by holding down the red ON/OFF
button until you hear 3 descending tones.
