Signal Level, Leakage & Home Wiring Test Kit: CLI-1750/LST-1700
The Home Wiring Test Kit provides a comprehensive measurement set of tools for troubleshooting home wiring, as well as performing loop loss tests for cable modem installation Mini-Sweep measures the frequency responses that must be accurate for digital or internet services with the CLI-1750 by receiving LST-1700 sweep signals; frequency characteristics of reverse path can also be obtained The FDR Mode can identify the location and magnitude of impedance mismatch caused by poor connections, cut wires, bad terminations, providing a distance-to-fault reading with no dead zone Leakage can be detected and measured with the CLI-1750 by receiving leakage monitoring signals from the LST-1700 transmitter Combination Signal Level Meter, Leakage Meter and Home Wiring Test, all in one kit 95% of all forward and reverse ingress and interference is located in the distribution and home network. Advanced ingress spectrum scan helps locate the source fast and easy Complete digital measurement solution for DTV and cable modem signals; digiCheck average power measurement including auto limit check
Extensive testing shows that one of the main challenges to successfully offering new, digitally based services is the existing wiring in the customers home. Digital services, including audio, video, Internet, and telephony are less tolerant than traditional analog services of frequency response problems, reflections, group delay, and ingress caused by inferior componetry or poor craftsmanship. Will the existing wiring deliver the quality the customer demands? Should the network provider or homeowner plan to rewire when digital services are activated? You need tools to help answer these questions quickly and accurately because replacing wiring makes new service activation costs high, often limiting the acceptance of new services. The Model CLI-1750, used in conjunction with the Model LST-1700 Signal Transmitter, helps identify and locate potential problems with the distribution network and home wiring prior to activating these new services. The CLI-1750 and LST-1700 are compact home wiring testers capable of measuring not only routine power levels, but also digital average power, leakage, frequency domain reflectometry (FDR), and sweep, which can be useful for a wide range of trouble shooting from installation to characterizing existing wire. The instruments superior user interface and performance can reduce the installation time and repair cost. Designed for use by installers, the CLI-1750 and LST-1700 are easy to use, portable, and economical solutions that perform a comprehensive set of tests to verify the quality of the installation. With these instruments, signal levels are checked to verify proper levels arriving at the tap and the house according to design and government regulations. Frequency response is measured to verify proper losses as a function of cable length, type, number of passive components, and to uncover any roll-off or sharp changes in response. A FDR test reveals precise location of sources of reflections, degree of severity, and enables surgical replacement of faulty cable or components, or repair of craftsmanship problems. A reverse ingress scan test shows the presence of noise or ingress generated in the home that hampers reverse communication for all customers sharing the node. A leakage test finds potential points of ingress because the source of ingress may not be in operation while the installer is at the house.

Ingress is Egress
Ingress is the is the most serious problem on interactive reverse path services. Ninety-five percent of all ingress comes from the home and distribution network. Leakage and ingress are directly coupled problems. A leak out can also be an opening for ingress to enter the cable system.

Leakage Measurement
The flexible configuration menu allows customization of all leakage parameters. Frequency agility allows the user to 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 LT-1000 Leakage Tagger, a special tag alarm can be programmed for use in overbuild situations.
Measurement Mode
Leak Level
Alarm Volume Leakage parameters can be customized in Configure mode. Analog Meter Scale 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 measurement is performed on active (unscrambled) video carriers.This mode is more accurate but less sensitive than the Find & Fix mode. 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 to the leak source. The large, numeric readout quickly updates the leakage signal strength.The graph automatically rescales in the Find & Fix mode providing an easy-to-interpret graphical view of the leak response.

Level Measurement
CLI products provide a comprehensive single-channel display and a multi-channel display with pass/fail indicators that quickly and clearly indicates whether all channels are being received at the subscribers drop at appropriate system design levels.
The single-channel display shows the video and audio carrier levels and the difference between levels. (Compatible with dual sound and NICAM.)
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.

Installation Check
Pressing the 3 single 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.
The results are displayed in a list indicating which parameters are out of tolerance. If all levels are within limits, a 3 appears in the right far column. If any parameter is out of tolerance an x will be shown.
Pressing the Cycle soft key provides more detail by displaying a list of all channels. Passing channels are indicated by a 3 in the right hand column.
Pressing the Cycle soft key provides a detailed view of errors by specific channel.
These results can be printed or downloaded to a 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 networks are within specifications, or to gather 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, technicians can record information about the location at which the test is being performed. Files can be created for commonly tested locations so technicians only need to enter the information once, and a test report can be printed for each interval. Or a comprehensive 24 hour report can be generated to that summarize all data collected from up to four intervals.
The tilt display shows six channels and updates in less than a second.
Auto Test results are time, date, and temperature stamped and can be stored, viewed, printed, or uploaded to JDSUs StealthWare software.
CLI-1750/LST-1700
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.
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.
In the Configure mode both analog and digital limits can be set to guarantee correct test results.
