  • Page 106 – 7859 – ONSTELLATION: Control mean for the quality of the signal by a group of points making spots on the screen of the field meter. The more circular and distinct the spots of the constellation, the better the quality of the signal.
  • Page 107 – 7859 – REQUENCY: Parameter that characterizes the radio-electrical wave. It is measured in “Hertz“. We usu- ally use some multiples of this unit: kilohertz (kHz), megahertz (MHz), gigahertz (GHz). ex.: At Saint Etienne (Guizay), the TF1 frequency is 583.25 MHz P/LP: high/low priority ...

  • Page 109 – 7859 – LP : (Physical Layer Pipe) from 1 to 256 channels are available in DVB-T2 to transport inde- pendent multiplexes. OLARIZATION: Polarization of a signal from the satellite. It can be either: linearly polarized, horizontally or vertically: Circularly polarized to the right or the left In ground reception, the polarization is generally horizontal (the stalks of antennas are horizon- tal).
