Leakage detection in cable TV networks

Since the digitization of terrestrial TV, many countries have discontinued TV broadcasting in the UHF range. The freedup frequencies are now available as digital dividend for other services such as LTE. Since cable TV continues to use the UHF band, leakage in broadband cable networks will become the most frequent cause of interference in LTE networks. R&S®EFL110/210 is the ideal tool for detecting this leakage.

The R&S®EFL110/210 can be carried using a shoulder and waist strap so that users have both hands free for working with the antenna. When the directional antenna points at an interference source, the R&S®EFL110/210 immediately registers an increase in level. The measured value is visible for a while in the spectrogram display, allowing users to see radiated emissions that were only briefly indicated by the antenna. Using the spectrogram, users can move the antenna back until the interference is visible again and the antenna points to the source. Users follow the antenna movement with their eyes, and the R&S®EFL110/210 supports them by generating an acoustic signal. The pitch of the tone is proportional to the measured field strength.

Once the source of interference is detected and corrected, the R&S®EFL210 TV test receiver can be used for a final test of the TV signal quality.

The R&S®EFL110/210 is small, lightweight and robust and has been optimized for outdoor use. Its 5.7" display adapts itself to the ambient brightness and is always clearly visible. A special daylight mode makes it possible to read the display even in bright sunlight.
