The Electronic Programme Guide is an additional function of many DVB receivers. This can
show the broadcast information provided by the broadcasters, provided
that it is available, graphically on the screen for the user, thus providing an overview of the
current programmes. In TechniSat units this programme guide is called SFI or SFIplus and
contains additional functions. See SFI/SFIplus.
Frequency
Physical size, indicates the number of vibrations per second, the unit is the Hertz (Hz).
Frequency range
a) Satellite or LNB:
11 GHz range from 10.70 GHz - 11.70 GHz, 12 GHz range from 11.70 GHz - 12.75 GHz
b) Receiver: Intermediate frequency, or 1. ZF 950 to 2150 MHz
Unit Description Vibrations per second.
1 Hz 1 Hertz 1
1 kHz 1 Kilohertz 1.000
1 MHz 1 Megahertz 1.000.000
1 GHz 1 Gigahertz 1.000.000.000
Coaxial cable
Connection cable between LNB and satellite receiver for transmission of received signals
and power supply for the LNBs.
LNB/LNC (Low Noise Block converter)
Reception unit at the focal point of the antenna, converts the frequency range of the satellite
into the intermediate frequency of the digital receiver.
LOF
Local oscillator frequency; data in MHz or GHz; depending on LNB and received
frequency range
Reception frequency of digital receiver = broadcaster frequency of the satellite LOF.
Modulation at 22 KHz
Apart from the 14/18 Volt switching facility, this serves to switch between 2 LNBs. In the case
of a Universal LNB it serves to switch to the High-Band range
Parabolic dish
Dish made of metal or coated synthetics, with a parabolic shape, to focus the
electromagnetic waves broadcast by the satellite at a focal point
Polarisation plane
To better utilise the available frequency range, satellites are configured so that neighbouring
transponders broadcast with opposite polarisation (horizontal and vertical or laevo-rotatory
and dextro-rotatory). To receive both polarisation planes you will require two single
LNBs or a V/H LNB.
