CLI-1450/CLI-1750
Combination Signal Level/Leakage Meters
Key Features
Finding the Egress Helps Find and Fix the Ingress.
RF signals leaking out of your system can also indicate RF signals leaking in.
Repairing any potential points of ingress/egress will reduce or eliminate unwanted
incoming and outgoing interfering RF signals. This not only translates to
compliance with government or system leakage (egress) regulation, but also
translates to reducing ingress noise that can affect reverse path services.
JDSU has embraced the “Find and Fix” concept in the design of the CLI-1450/
CLI-1750 Combination Signal Level and Leakage Meter. A frequency agile leakage
mode makes quick work of finding and fixing leakage sources. The Ingress Scan
feature identifies ingress problems from the tap to the drop. In addition, the same
reliable signal level meter functions found in the MicroStealth are in the CLI
products, eliminating the need to carry multiple meters.
Faster “Find and Fix.”
The CLI design enables installers to do their jobs faster and easier. First, all meters
are lightweight and easy to carry, yet durable and water-resistant. Second, all have
a user-friendly, icon-based user-interface. The simple icons are used in all CLI
meters, and all other JDSU field meters. This means less training and less
downtime for field techs & installers. Finally, the user interface is also available in
international languages, allowing for ease of use throughout the world.

This fast mode is used
for drop-to-subscriber
and inside the home
applications. The fast Find & Fix
Mode assists in quickly guiding
the technician towards the leak
source. The large numeric readout
is able to quickly update the leakage signal strength. The graph will
do an auto rescale in the "find and
fix" mode providing a graphical
view of the leak response.
LT-1000 Leakage Tagger
The distinctive signal tagging from the LT-1000 assures the technician
that detected leaks are not being generated from competing systems in
overbuild situations. The Leakage Tagger modulates the video signal
under test at user programmable rates, and improves detection
sensitivity in noisy environments.
Ingress Scan
The innovative ingress scan mode finds forward and reverse ingress problems from the tap to the drop. Start/stop
frequencies, resolution, and dwell time are programmable in the set-up menu. The operator can also set a limit
threshold for simple identification of problem drops. To check for intermittent ingress, the meter can be adjusted to
the peak hold mode to capture transient signals. Ingress scan displays can be saved for later printing or uploading to
StealthWare software.
Testing the reverse path spectrum for sub-band signals being generated in the drop system improves the effectiveness of
finding ingress sources and common path distortions.
Leakage Measurement
The flexible configuration menu allows customization of all leakage parameters. Frequency agility lets the user select
any test signal from 115-140 MHz. Leakage alert threshold limits can be set for system or regulatory standards.
Visual and audible alarms can be enabled to alert the operator when threshold limits are exceeded. When used with
the LT1000 Leakage Tagger, a special tag alarm can be programmed for use in overbuild situations.

The Measurement Mode is used for “ride-out” driving applications,calibrated leaks,and FCC/CENELEC
testing.A numeric readout and audible alarm quickly alert the user when leakage threshold limits
have been exceeded. The leakage measurment is performed on active (unscambled) video carriers.
This mode is more accurate but less sensitive than the Find & Fix mode.
A display of the spectrum with clear pre-set limits
allows the installer to easily identify ingress. All
intermittent ingress is detected through flexible
dwell-time setup.

N/A
Pressing the “cycle”soft key
provides a detailed view of
what specific error is on the
specific channel.
Pressing the “cycle”soft key provides
more detail by bringing up a list of
all channels. Passing channels have
a “3” in the right hand column.
The results are displayed in a list
indicating which parameters are
out of tolerance. If all levels are
within limits, a “3” will be in the right far
column. If any parameter is out of tolerance
an “x” will be shown.
The six-channel scan shows six
different user-defined video
carriers, with pass/fail indicator
for user-defined limits.
The Full Scan display shows all
user-defined video carriers.The
unique limit check feature quickly checks the results against
user-defined analog and digital limits.
Level Measurement
CLI products provide a comprehensive single-channel display and a multi-channel display with pass/fail indicators.
This quickly and clearly indicates if all channels are being received at the subscriber’s drop at appropriate system
design levels.

CLI-1450/CLI-1750
The single channel display shows the
video and audio carrier levels and the
difference between levels. Compatible
with dual sound and NICAM.
Installation Check
Pressing the “3“ key provides an installation status check which allows users to verify that all levels are within user-
defined limits. Up to four different limits can be configured: tap, ground block, subscriber drop, and custom. This
feature can be used to determine if a subscriber connection meets cable networks or government specifications.
These results can be printed or downloaded into the PC for report generation using StealthWare™ Data Analysis Software.
Tilt Mode
Tilt measurement is a fast and effective method to balance line extenders
and in-home amplifiers.
Auto Test
To certify that the network termination and home network are within the
specifications, or for proof-of performance compliance data, an auto-test
can be performed. Tests can be executed immediately or scheduled over
a period of time. When configuring an Auto Test, you can record information
about the location at which the test is being performed. Files can be created for
commonly tested locations so you need only enter the information once.You can
print a test report for each interval, or a comprehensive 24 hour report that
summarizes data collected from up to four intervals.
Customized Channel Plans
Channel plans can be built, stored, and edited. This is convenient if you
use the meter for more than one plant. You can quickly selelct the correct
channel plan at which you are working. It’s only necessary to build a
chennel plan once. A “cloning”funtion makes it possible to easily transfer channel
plans from one field instrument to the other. StealthWare™ software enables you
to upload and download channel plans from your PC to the meter.
digiCheck™ Digital Signal Measurement
Making accurate digital average power and performance
measurements are addressed with the digiCheck™
measurement function. The digiCheck™ average power
measurement takes small slices of the integrated RF-energy, summing them
together to provide one total power reading. It takes into account the channel
flatness of the digital carrier itself.

CLI-1450/CLI-1750
Auto Test results are time, date, and temperature
stamped and can be stored,viewed, printed, or
uploaded to StealthWare™ software.
The tilt display provides a display of six channels
that updates in less than a second.
Digital-TV and forward cable modem signal
"Small-band" digital carriers, like cable telephony, require a different measurement technique. For that purpose, the
digiCheck™ feature offers a time average as well. Even in this case, all level readings are fully compensated for by the correct
occupied bandwidth.
“Small-band” digital signals are like cable
telephone carriers.
The digiCheck™ method of measuring the total integrated RF-power under the haystack is very
reliable and accurate. All level readings are fully compensated for by the correct occupied bandwidth.
Digital and Analog Limits
Cable networks have analog and digital carriers. The levels of analog and digital signal measurements are different
according to standards and regulations. Digital signals are typically 6-14 dB below analog signals. Users can enter
minimum and maximum digital channel level limits separately from analog limits. Scan Mode, Installation Check,
and Auto Test will accurately measure both digital and analog signals. This allows easy identification of the pass/fail
condition of both channel limits sets.
StealthWare™ Software
Signal level measurments can be uploaded for storing, viewing, and printing. StealthWare™ allows you to build channel
plans and test locations which can be downloaded to the field meter.
Multi-Lingual LCD Screen
The user interface is now fully converted in the international language requested: French, Portuguese, German, Spanish,
Italian, and Dutch.
Mini-Sweep and Fault Locator
When paired with the CLI-1750, the optional model LST-1700 Transmitter adds 5-862 MHz Mini-Sweep
and FDR Fault Locator for qualifying in-home wiring. The CLI-1450 can be upgraded for full
compatibility with the LST-1700.
