Worldwide presence Dark grey indicates countries that have adopted or deployed LNB X-SQUARE 2012 LNB... LNB (low noise block downconverter), is the low signal frequency reduction amplifier, it is composed by the LNB with LNC, LNC by the mixer, the local oscillator constituted. before arrival at the antenna, the satellite signal is quite weak and the greater the higher the frequency of the signal loss of coaxial cable transmission, So need LNB to zoom in, and also not be too much to deterioration of the signal to noise ratio. The LNB s workflow is first satellite high frequency signal amplification, reuse local oscillator circuit to convert the high-frequency signal to an intermediate frequency 950Mhz - 2150Mhz (determined in accordance with LNB type intermediate frequency range) and again enlarged to facilitate the transmission and satellite coaxial cable the receiver demodulates and work. 8

About LNB LNB Parts An LNB has several components. An input filter assures that only signals from satellites enter the LBN. The low noise preamp amplifies the satellite signal to a usable level. A local oscillator and mixer down-convert the signal to an intermediate frequency that carries the TV channel information. The output filter removes any unwanted signals that may cause interference, and a final amplifier increases the IF to a more usable level to travel through the cable to the receiver. The output power of an LNB depends upon the strength of the signal received and the design of the LNB. System LNB Testing Numerous satellite TV systems installed by service providers such as Dish Network and DirecTV have system tests that reveal a failed LNB. The process of testing a system depends on the model of the receiver, but the user's manual illustrates how to do it. Your TV screen shows the results of the system test. If the LNB is not functioning properly, a message will display that clearly says so. Run a system test using your remote control. If a defective LNB message appears, call your service provider to send a technician. Service is usually included in your subscription price. LNB Tester or Meter Use a meter to test the power of the signal coming out of an LNB. A standard radio frequency power meter will show the level dbm, but it requires external power to operate. The meter may also be expensive. The power output should be from -80dBm to -25dBm. Smaller, less expensive meters designed for home satellite systems connect between the LNB and the receiver. The LNB gets the voltage needed to operate the electronic circuits from the receiver through the cable. An LNB in-line tester uses this power. Install it between the existing cable and the LNB to read the signal level. 10

Noise figure Bearing in mind that the ideal situation is to have a minimum amount of noise across the entire frequency band. Every LNB is different because of manufacturing tolerances. Measuring LNB noise is time-consuming and can't be done for LNBs selling for just a few pounds each. Instead, the manufacturer will make a few checks at specific frequencies on a few random samples. Without a full graph showing the actual measurements of the LNB that you buy, it's impossible to know what you have got. The manufacturer may state a "typical" or "minimum" noise figure but that's based on measurements of only a few random samples at a specific frequency. In the end, you have to rely on results. If a lot of people say "the A quad-output LNB works for me in a fringe reception area with a dish made by B and a receiver made by C" then that's probably the best information you are going to get. (If you are not in a "fringe reception area", just buy the cheapest. It won't make any difference whatsoever to your picture quality or rain margin. The dish size is much more important. If in doubt, buy a "Sky zone 2 minidish" or larger.) The "0.1dB" specification is utterly meaningless. Seriously, once the noise figure is below 0.6dB right across both bands (Hi and Lo), then lowering it further (even if that were technically possible, which it isn't) would make no discernible difference to reception.
