1. General 2. Delivery volume 4. Charging 3. Measurement principle The is a impulse reflectometer, processor controlled, with LCD display for check and locate faults in telecommunication and power cables. For a more accurate analysis the return loss of coaxial cables is measured additionally. It is handy and easy to operate. The special features are: already 20 cable types are pre-programmed, additional types can be added in the men ...

By long pressing of the button 3 - until the icons appear inverted - you get to the first parameter of the measurement. Here can be set with the buttons 1 or 2 the required value. During switching on the state of charge of the battery in the display ...

If the zoom is switched on, the entire display is used for the display of the measuring curve. An already set gai ...

0.80 / 3.50 CPE ON P: 1 v/c=0.83 5.7 dB 8. Measuring with the pulse reflectometer 8.1 Basic principle The basic physical principle is the echo. There are here signals sent out in e.g. the form of sound. If they hit an obstacle, then a part of it is sent back again, therefore reflected. Simple examples are the echo of a rock wall or the sonar in the maritime. This principle works the same as well on electric lines. Only one takes as ...

back at the sending point. To get accurate results, you need to pay attention to something: e. g., that the cable offers a resistance to the signals. This in turn depends on the structure of the cable. There is except of the cable loss still a very important parameter - the propagation factor. Very important for coaxial cable is the characteristic impedance and consequently the adaptation or matching. On this basis the measurements ...

Measuring cursor determined length propagation factor at 8.3 Length and distance measurement - for the practitioner The main application of a pulse reflectometer is determining the cable length, either the length of a laid cable or the distance routed to a certain modification, such as cable failure, inserted component. There are only two ideal states: 1. The cable matches - only transmit pulse recognizable Resistance equal to 75 o ...

An important statement about the quality of a cable or components present in the line allowed the return loss, also reflection attenuation (dBRL) called. Since most taps and splitter have a lower return loss as coaxial cable, it is of interest if these are still intact. In intact coaxial cables the return loss is in the range of about 45 ... 65 dB. Everything else indicates more or less an existing fault. For the passive components ...
