MODEL CLI-1450 1 Introducing the CLI-1450 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.
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.
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.
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.

MODEL CLI-1450 2 Using the CLI-1450 INTRODUCTION The best way to learn about the CLI-1450 is to use it. Section 2 discusses the individual measurements available with the CLI-1450. Each measurement mode discussion includes detailed descriptions on how to perform the measurement as well as operating controls and indicators. LEAKAGE The CLI-1450 has two sub-modes of operation that detect and measure RF leakage: the Measure mode and the Find and Fix mode.
You can read the leakage measurement numerically and on an analog meter. The units in which leakage is being measured appears directly below the meter. Note You can select the units you want to measure leakage in when you configure your CLI-1450 (see LEAKAGE UNITS in the Leakage Configuration section). The frequency being monitored appears in the upper right-hand portion of the screen.
MEASUREMENT PEAK The peak leakage value is indicated on the analog meter as a solid line. It also appears numerically as shown below: The peak value is reset periodically. You can specify how quickly you want it to reset (see PEAK HOLD RESET PERIOD in the Leakage Configuration section). Tip You can manually reset the peak value at any time by pressing the SHIFT + keys. ADJUSTING THE ALARM VOLUME An audible sound is produced when the alarm is triggered.
Note The characteristics for each type of antenna are programmable. Be sure that you have enabled all the antenna types that you want to use. soft key is only available if there is more than one enabled The type. (see EDIT ANTENNA TYPES in the Leakage Configuration section). Note The antenna selection is only useful for field strength measurements. If the measurement units you have selected result in an absolute measurement, the soft key will not be available.
COMPENSATION Compensation allows you to adjust your CLI-1450 to a calibrated leak field (see Appendix D). Press the soft key to adjust compensation.

MODEL CLI-1450 D Appendix D: Setting Up A Calibrated Leak Field INTRODUCTION Regardless of the type of vehicle-mounted antenna used, several variables come into play that could cause a change in measured field strength. The position of the antenna on the truck will affect the ground plane and, therefore, the pattern of the antenna. There may be reflections from other devices mounted on the vehicle (ladder racks, etc.).
SETUP The frequency and level of the predictable “leak” should be given careful consideration, to avoid interfering with any off-air service or allowing an off-air service to affect the measurement. This leak should be generating a signal only during calibration and disconnected at all other times. A bandpass cable drop may be used as the leak signal, with a calibrated dipole as the source antenna. (A fixed dipole or a WWG HD-1 may be used as the source antenna.
b. Source antenna should be carefully located to isolate it from sources of reflection. c. Source antenna should be properly polarized (vertical, if vertical receiving antenna is used). 2. The following considerations should be taken into account when taking measurements using a reference leak source: a. Use a half-wave dipole when taking measurements. b. Place dipole 10 feet from the source antenna and 10 feet from ground, oriented with same polarization as source antenna.
Important Your CLI-1450 stores a separate compensation value for each antenna type. The value automatically becomes effective when you select the antenna. If you are using a calibrated leak field, be sure to make the adjustment for each type of antenna that you want to use.
MODEL CLI-1450 E Appendix E: Technical Note VMA-3 INTRODUCTION The VMA-3 Quarterwave Antenna is a field tunable antenna designed to perform leakage measurements when used with the WWG Model CLI-1450 leakage meters. The field tunable 1/4 λ antenna can be cut to any frequency in the 115-140 MHz range. INSTALLATION The VMA-3 is easy to install. To adjust the VMA-3 antenna to the desired frequency: 1. Using the cutting chart, locate the desired frequency on the horizontal axis. 2.
It is highly recommended that the element be cut long and trimmed down to the exact frequency desired. 5. Cutting the element may be easier by using the edge of a file or grinding wheel to score the rod around its circumference. Then snap it off with a pair of pliers. Always cut from the bottom of the element. 6. Insert the element all of the way into the base assembly and tighten with a 3/32" hexagon screw key. De An sired ten na Le 24 ng 23.
OPERATION For normal measurements, connect the connector on the antenna assembly directly to the antenna connection on the Model CLI-1450 leakage meter or to the DS-1 Docking Station. The antenna used in leakage detection is also referred to as a quarter-wave antenna because it is equal in length to one-quarter the measured wavelength in free space. An antenna's response (receiving or radiation) pattern is determined by its ability to receive or radiate signals better when tuned or pointed in one direction.
