Introduction & Operation
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 signicantly. 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 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.

Battery Charging
Before you can use your instrument, you will need to charge its battery. Your instrument’s
battery pack provides approximately 8 to 10 hours of power during continuous operation.
The instrument comes with a AC to DC Power Adapter & Battery Charger which can be used to
charge the battery in approximately 3 hours or to trickle charge the battery while the instrument
is in use.
Plug the power adapter & battery charger into the DC charge port of the Seeker D Lite Source
Transmitter on the left side of the instrument under a protective cover.
Your instrument is equipped with a “smart” battery charging circuit so that the charging method
(fast or trickle) is an auto function. Fast Charge is used to charge the battery quickly. Trickle
Charge is used to keep the battery fully charged.
Every time your instrument is plugged into the charging cube, it starts charging automatically
via the Trickle Charge method. If the unit determines Fast Charge is necessary, it defaults to
the Fast Charge method.
Battery Charge Indicator LED
The Battery Charge Indicator LED is located on the front panel of the Seeker D Lite
Source Transmitter. This LED indicators represent the status of the internal battery and its
charging status.
The LED will illuminate when the Seeker D Lite Source Transmitter is connected to the
charger and the following conditions are met:
• A solid Green LED is displayed when the batteries is fully charged.
• A solid Red LED is displayed when the batteries is charging.
• A ashing Red LED is displayed when the battery or charging circuit has a fault.
In this case, the meter will need to be serviced by a VIAVI Certied Repair Center.
Before sending in the unit for repair, contact us for an RMA.
• The LED is not displayed when there is no power supplied to the charger.

Operation
Once the instrument’s battery is charged, you may startup the Seeker D Lite Source
Transmitter by pressing the ON/OFF button on the front of the device. To shutdown the Seeker
D Lite Source Transmitter, simply press and hold the power button for two seconds.
If the Seeker D Lite Source Transmitter has been powered on and idle for ten (10) minutes, the
device will shutdown automatically to conserve battery power.
Power Indicator LED
The Power Indicator LED is located on the front panel of the Seeker D Lite Source
Transmitter. This LED indicator represent the status of the instrument and will illuminate
when the Seeker D Lite Source Transmitter is powered ON and the following conditions are
met:
• A solid Green LED is displayed when the battery charge is full and the device is
operating normally.
• A solid Red LED is displayed when the battery charge is low. When the battery
charge drops to this level, it is recommended that the battery is charged soon.
• A ashing Red LED is displayed when the battery charge is very low. When the
battery charge drops to this level, it is recommended that the battery is charged
immediately.
• The LED is not displayed when the Seeker D Lite Source Transmitter is shutdown.
Transmit Level Adjustment
The Transmit Level Indicator LED will illuminate when the Seeker D Lite Source
Transmitter is powered ON. To change the output level, simply press and release the
Transmit Level button.
This LED indicator will illuminate as follows for the transmit level that is currently selected:
• A solid Green LED is displayed when the transmit level is set to 23 dBmV.
• A solid Red LED is displayed when the transmit level is set to 43 dBmV.
• A ashing LED is displayed when the transmit signal circuit has a fault which can
lead to an unreliable source output. In this case, the meter will need to be serviced
by a VIAVI Certied Repair Center. Before sending in the unit for repair, contact us
for an RMA.
