1 Hz 1 Hertz 1

1 GHz 1 Gigahertz 1.000.000.000
Frequency range:
a) Satellite resp. LNB:
11 GHz range from 10,70 GHz - 11,70 GHz, 12 GHz range
fromn 11,70 GHz - 12,75 GHz
b) Receiver: Intermediate frequency, or 1. IF 950 to 2150
MHz
Intermediate frequency:
The frequency range transmitted by the satellite cannot be
transmitted via cable, and is therefore converted by the LNB
to the intermediate frequency range of 950 to 2150 MHz.
This makes transmission possible, and allows the digital
receiver to process the signal.
1. IF = intermediate frequency
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 frequen-
cy of the digital receiver.
LOF:
Local oscillator frequency: stated in terms of MHz or GHz;
varies depending on the LNB and the frequency range recei-
ved.
Receiving frequency of the digital receiver = broadcasting fre-
quency of the satellite - LOF
Modulation at 22 KHz:
Apart from the 14/18 Volt switching facility, this serves to
switch between two LNBs. In the case of a Universal LNB it
serves to switch to the High-Band range
OSD:
O
n S creen D isplay (messages and menues shown on
screen)
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
PID:
P
acket Id entifier, Packet-ID
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.
Receiver :
The signals received by the DVB-T antenna, resp. received
and converted by the LNB cannot be processed by the televi-
