| The PROLINK4 Premium is the most
advanced, versatile and precise instrument of its range. Analog signals,
Level, Video/Audio and Carrier/Noise measurements are available. For digital signals, the instrument measures Channel Power, Carrier/Noise and Bit
Error Rate (with DVB Channel Identification as well as MPEG-2 decoding and wrong
packet detection). For BER measurements on QPSK (Satellite) signals, the measurements is taken before and after the first correction algorithm (Viterbi), thus obtaining the necessary information to verify. It complies with all DVB recommended quality parameters. To ensure quality reception on CATV networks, BER and MER is measured, as well as, an analysis of the return path. For Digital Terrestrial Television (COFDM), measurements of BER and CSI (Channel Status Information) are taken within necessary parameters to quantify the quality of such a transmission system. Apart from the already mentioned measurements, the PROLINK-4 Premium monitors the number of wrong packets received over a certain period of time, with the objective of finding out what caused the interruptions. Another interesting function is the automatic identification of the services provided by the operator (PROMAX patent), as well as the ability to decode MPEG-2 signals and visualize them on the monitor as you would with an analog signal. Equipped with Li+ batteries, the PROLINK-4 Premium has an autonomy of more than 3 hours with a very reduced charging time and without the inconvenience of the memory effect. It is ideal for field use because it has been designed with shock protectors to cope with drops and small hits. The entire instrument, including the front panel, is prepared so to support changing environmental conditions such as dust and rain. The instrument comes with a carrying bag. An optional hard carrying case is available. |

The impulse response We introduce the new channel impulse response function for PROLINK-4C Premium and PROLINK-4 Premium. This function will be included as standard in the instruments of new delivery. If required, it is also possible to upgrade the firmware of the instruments in the field. Quality of the digital signal The PROLINK-4 Premium and PROLINK-4C Premium include many other functions to determine the quality of the DVB-T signals. For example, the measurement of Power, C/N, BER, CSI and MER. The Bit Error Rate (BER) is a parameter that determines the limit of acceptability of the signal. This limit is established by DVB. But to define the quality of the signal other measurements such as CSI or MER have to be taken in consideration. Such parameters will determine the noise margin or, in other words, how far we are from the limit of acceptability. The constellation Another very important and complementary function to that we have described previously is the constellation. A well designed and perfectly synchronized transmission system does not assure a reception free of errors in all the coverage area. The constellation function allows to analyze each one of the QAM carriers within a COFDM signal: 1705 in the system 2k and 6817 in 8k. Transport stream analyzer This function allows the detection of impulsive noise affecting the signal reception. The impulsive noise is mainly caused by home appliances, vehicles, etc. These interferences are easily leaked through the antenna and can affect the reception, but they are not always present. |
