MODEL CLI-1450

Introducing
the CLI-1450

1

INTRODUCTION

The CLI-1450 Leakage/Signal Level Meter is a high performance
instrument designed for cable television technicians. The durable,
water-resistant CLI-1450 makes innovative use of a graphics LCD to
simplify operation. The LCD backlight makes measurements easier
in crawl spaces and behind television sets. The display is also easy to
see in bright sunlight.

LEAKAGE DETECTION AND MEASUREMENT

Your CLI-1450 is a highly sensitive, hand-held leakage meter that
makes finding and measuring RF leakage easy. Because it can
accurately detect and measure video signals, it is not necessary to
inject an additional RF carrier for the purpose of monitoring leakage.
Your CLI-1450 is frequency agile — you can configure it to monitor a
carrier frequency between 115 to 140 MHz.

You can use the optional LT1000 Leakage Tagger to modulate an
existing carrier with a distinct tag signal. This enhances detection
sensitivity in noisy environments and reduces false alarms. In
overbuild situations, you can determine if a detected leak is emanat­ing from the network that you are testing.

An audible alarm notifies you when your CLI-1450 has detected a
leak. You specify the level threshold at which the alarm is triggered.

1-1

To reduce the likelihood of false alarms, you can configure the alarm
to occur only when a tag signal is present. You can quickly adjust the
volume of the alarm and even mute it if desired.

Your CLI-1450 makes the accurate leakage measurements that you
need to verify compliance with government regulations. The type of
antenna you are using and the distance from the leak are considered
when measuring field strength. You can select from among four
antenna types — monopole, dipole, vehicle mount and custom. The
antenna factor for each type is programmable.

The most accurate and repeatable measurements are made using a
dipole antenna located at the required reference distance. This is the
only method recommended by Wavetek Wandel Goltermann for
making compliance measurements. You can also make approximate
measurements up to 30 meters away by entering the estimated
distance from the leak. Your CLI-1450 will calculate what the
equivalent field strength would be at the reference distance. These
measurements are adequate for grading leaks you have found and
prioritizing your repair schedule based on leak severity.

The CLI-1450 has the ability to interface with GPS tracking systems
using its built-in serial port.

LEVEL MEASUREMENTS

Your CLI-1450 performs accurate signal level measurements — even
on scrambled channels with horizontal or vertical sync suppression. A
scan mode allows you to see the levels of all carriers in a spectral
display. You can also view level measurements at a single frequency
or for a specific channel. When tuned to a channel, the display
indicates the levels of the video and audio carriers, and the difference
between the carrier levels.

When performing an installation, you can press the Installation Check
key to quickly verify that all channels are within limits that you have
defined. You can use this feature to determine whether or not a
subscriber connection meets government regulations.

A special channel plan building mode automatically determines

1-2

which channels are active on your cable system. Once you have
defined a channel plan, you can copy it to other units. You can also
create channel plans using StealthWare (Version 3.0), the Windows™
based data management package for Stealth products.

For documentation purposes, you can print any measurement screen
to a serial printer (Wavetek P-Stealth Printer). Following an installa­tion check, you can print an installation report and file it with the work
order. You can also print a report that lists all configuration settings
including the channel plan.

The CLI-1450 tunes from 45 to 559 MHz with options to extend the
range to 5 to 890 MHz.

DIGITAL CARRIER MEASUREMENT OPTION 1450DIG

As digital services such as audio, video, Internet, and telephony
become more common, a way of accurately measuring their carriers is
needed. The 1450DIG digital carrier measurement option provides
an average power measurement of QPSK, 16-QAM, 64-QAM, 256­QAM, QPR, BPSK, CAP-16, and other modulation schemes. To be
measured, carriers must be in a state of continuous (i.e., non-burst)
transmission.

MEASUREMENT LOGGING (signal level modes only)

With the CLI-1450, you can store installation checks that you have
performed throughout the day. You can also store scan and tilt
measurements. Each file is time and date stamped and can be recalled
later for viewing on the LCD screen.

When viewing a file, you can adjust the screen settings the same as
when you are viewing a “live” measurement. Using the built-in serial
port, you can print files and even upload them to StealthWare (Version

3.0) for further analysis and archiving.

AUTO TESTS (signal level modes only)

Automated tests are easy with the CLI-1450 and provide a convenient
way of acquiring proof-of-performance compliance data. Tests can be

1-3

executed immediately or scheduled over a period of time. To
conserve battery life, CLI-1450 shuts itself off between scheduled
intervals. 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.

Auto Tests results are time, date, and temperature stamped and can be
viewed on the LCD screen. Limits are applied to the measurement
data with out-of-tolerance conditions concisely indicated. You can
print a test report for each interval or a comprehensive 24 hour report
that summarizes data collected from up to four intervals. Auto Test
result files can be uploaded to StealthWare (Version 3.0).

MULTIPLE CHANNEL PLANS

The CLI-1450 stores channel plans that you have built and edited.
This is convenient if you use your CLI-1450 for more than one plant.
You can quickly select the correct channel plan for the plant at which
you are working.

DOCKING STATION OPTION

The DS-1 docking station simplifies connection to a vehicle antenna
and power source. Your CLI-1450 automatically recharges when
resting in the docking station. The adjustable arm makes it easy to
view the display from the driver’s seat.

REVERSE INGRESS SCAN

Reverse ingress scan is a feature of the sub-band option for models
CLI-1450 and MS1300. A continuous fast scan is performed that
permits the installer to see ingress signals in the reverse band. The
operator can set the start and stop frequencies of the scan, the interval,
and the scan rate (dwell). In use, once the installation is complete, the
meter can be connected to the tap end of the drop and the reverse scan
mode selected. A user programmable limit can be set for simple
identification of problem drops. To check for intermittent ingress, the
meter can be set in the peak hold mode to catch transient signals. The
screen can be saved for later viewing, printing, or upload to

fresh one as soon as possible.

This indicates that the RF synthesizer has become
unlocked. If this condition persists, the unit may need

repair.

A list can be either "active" or "inactive". You can tell by looking at the
border. If the border is solid, the list is active and any keys that you
press are directed toward it. If the border is dim, the list is inactive and
is not affected by key presses. Usually you can make a list become
active by pressing the key.

When there are more items in the list than can be displayed at one
time, a scroll bar appears along the right-hand edge of the list. You can
use this to get an idea of where you are. When you have reached the
first or last item, an arrow appears inside the scroll box pointing to the
direction you can go.
