Introduction
Today, satellite communications is an important means for broadcast distribution of television and radio programs to
homes. Satellites transmit signals that can be received directly by mass deployed consumer electronics equipment. The
present document concerns the performance of this kind of equipment with regard to harmful interference. The
avoidance of receiving or transmitting interfering signals is considered in the present document, whereas reception of
the wanted signals is not considered. Satellite operators or broadcasters may create specifications for the latter purpose.
The present document is intended to cover the provisions of Radio Equipment Directive [i.1] article 3.2, which states
that "Radio equipment shall be so constructed that it both effectively uses and supports the efficient use of radio
spectrum in order to avoid harmful interference". The directive requires that unwanted radio wave emissions of
transmitters are limited in order to avoid harmful interference. It requires that receivers are resilient against harmful
interference from radio waves in shared and adjacent frequency channels. In addition to the present document, other
ENs that specify technical requirements in respect of essential requirements under other parts of article 3 of the Radio
Equipment Directive [i.1] may apply to equipment within the scope of the present document.
The R&TTE Directive [i.3], which is the predecessor of the Radio Equipment Directive [i.1], contains no receiver
requirements. Moreover, broadcast reception equipment is explicitly not covered. The present document becomes
necessary with the adoption of the Radio Equipment Directive.
An overview of satellite broadcast reception equipment is given in the following. Typically, the equipment comprises
an OutDoor Unit (ODU), and InDoor Unit (IDU), an Inter-Facility Link (IFL) between these units, and optionally
multi-switches for connecting multiple IDUs to an ODU. The ODU comprises an antenna and a Low Noise Block
converter (LNB). The frequency down-conversion by the LNB enables transmission on a coaxial cable to the IDU.
A frequency range that contains several modulated carriers is down-converted as one block. The most popular kind of
antenna is a parabolic reflector antenna with offset feed. In that case the feed horn is often integrated with the LNB into
one unit called Low Noise Block converter with Feed (LNBF). The IDU demodulates one of the carriers,
de-multiplexes the retrieved bit stream and decodes digital audio video and audio for display on a TV screen. Common
terms for the IDU are set-top box or satellite receiver. IDUs may contain a hard disk for recording programs. An IDU
may be capable of processing multiple carriers for direct viewing and recording. The IDU functionality may be
integrated into a TV set. Typically, the satellite transmits two electromagnetic waves with orthogonal polarization at the
same time. In case the satellite transmits a large frequency band, it is divided up for frequency conversion with different
local oscillator frequencies. The IDU selects by control signals which polarization and frequency band the ODU
provides on the IFL. An ODU may work with multiple IDUs or IDUs with multiple tuners via separate IFLs. Multi-
switches connected to an ODU allow connecting a large number of IDUs.
Frequency bands are re-used by satellites on different orbital positions of the Geostationary Orbit arc. Discrimination
between signals from wanted and adjacent orbital positions is provided by the directivity of the ODU antenna. The
actually required discrimination depends on the specific scenario of satellite spacing and Equivalent Isotropically
Radiated Power (EIRP), as well as on the robustness of the wanted signals. Moreover, a certain on-axis gain is required
for receiving the wanted signals with the target availability. In general, a larger antenna provides better discrimination
and gain, but on the other hand small antennas are better accepted by users and the public. Requirements on the antenna
are often given by means of the minimum antenna diameter. The meaning of such a requirement is "that the antenna
gain pattern shall be compliant with a reference pattern or mask that includes the nominal antenna diameter as a
parameter". The nominal diameter is a means for specifying and classifying antennas and in an easy way, but the actual
antenna diameter may be different from it, or the antenna might not be circular. The concept of gain pattern definition
with nominal antenna diameter is applied in the present document.

Besides the concept of ODU, IDU, IFL and optionally multi-switches, new concepts with different allocation of
functionality exist. With channel stacking or SatCR, frequency channels are re-arranged by the ODU or an additional
unit, so that all relevant channels can be carried on a single coaxial cable. IDUs or additional cables are connected by
simple splitters. With Sat>IP, the ODU or an additional device performs demodulation and conversion to video over
Internet Protocol. Common connected devices including tablet computers can be used to watch broadcast television
inside a home network. Another concept applies optical fibre to carry signals between ODU and multi-switches. In
conjunction with these and further concepts, the same requirements on the ODU characteristics exist.
The present document consists of multiple parts that apply to different kinds of equipment units, including ODUs for
specific frequency bands and IDUs.

The present document applies to ODUs for satellite broadcast reception from geostationary satellites in the frequency
band 10,7 GHz to 12,75 GHz. An ODU receives electromagnetic waves from a satellite. It amplifies the receive signal
at low noise, converts it to a lower frequency band and makes it available to the IDU on an interface.
Part of the IDU functionality may be integrated with the ODU. In that case the present document applies only to the
ODU functionality that is defined above.
The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the
efficient use of radio spectrum in order to avoid harmful interference.

Introduction
Today, satellite communications is an important means for broadcast distribution of television and radio programs to
homes. Satellites transmit signals that can be received directly by mass deployed consumer electronics equipment. The
present document concerns the performance of this kind of equipment with regard to harmful interference. The
avoidance of receiving or transmitting interfering signals is considered in the present document, whereas reception of
the wanted signals is not considered. Satellite operators or broadcasters may create specifications for the latter purpose.
The present document is intended to cover the provisions of Radio Equipment Directive [i.1] article 3.2, which states
that "Radio equipment shall be so constructed that it both effectively uses and supports the efficient use of radio
spectrum in order to avoid harmful interference". The directive requires that unwanted radio wave emissions of
transmitters are limited in order to avoid harmful interference. It requires that receivers are resilient against harmful
interference from radio waves in shared and adjacent frequency channels. In addition to the present document, other
ENs that specify technical requirements in respect of essential requirements under other parts of article 3 of the Radio
Equipment Directive [i.1] may apply to equipment within the scope of the present document.
The R&TTE Directive [i.3], which is the predecessor of the Radio Equipment Directive [i.1], contains no receiver
requirements. Moreover, broadcast reception equipment is explicitly not covered. The present document becomes
necessary with the adoption of the Radio Equipment Directive.
An overview of satellite broadcast reception equipment is given in the following. Typically, the equipment comprises
an OutDoor Unit (ODU), and InDoor Unit (IDU), an Inter-Facility Link (IFL) between these units, and optionally
multi-switches for connecting multiple IDUs to an ODU. The ODU comprises an antenna and a Low Noise Block
converter (LNB). The frequency down-conversion by the LNB enables transmission on a coaxial cable to the IDU.
A frequency range that contains several modulated carriers is down-converted as one block. The most popular kind of
antenna is a parabolic reflector antenna with offset feed. In that case the feed horn is often integrated with the LNB into
one unit called Low Noise Block converter with Feed (LNBF). The IDU demodulates one of the carriers,
de-multiplexes the retrieved bit stream and decodes digital audio video and audio for display on a TV screen. Common
terms for the IDU are set-top box or satellite receiver. IDUs may contain a hard disk for recording programs. An IDU
may be capable of processing multiple carriers for direct viewing and recording. The IDU functionality may be
integrated into a TV set. Typically, the satellite transmits two electromagnetic waves with orthogonal polarization at the
same time. In case the satellite transmits a large frequency band, it is divided up for frequency conversion with different
local oscillator frequencies. The IDU selects by control signals which polarization and frequency band the ODU
provides on the IFL. An ODU may work with multiple IDUs or IDUs with multiple tuners via separate IFLs. Multi-
switches connected to an ODU allow connecting a large number of IDUs.
Frequency bands are re-used by satellites on different orbital positions of the Geostationary Orbit arc. Discrimination
between signals from wanted and adjacent orbital positions is provided by the directivity of the ODU antenna. The
actually required discrimination depends on the specific scenario of satellite spacing and Equivalent Isotropically
Radiated Power (EIRP), as well as on the robustness of the wanted signals. Moreover, a certain on-axis gain is required
for receiving the wanted signals with the target availability. In general, a larger antenna provides better discrimination
and gain, but on the other hand small antennas are better accepted by users and the public. Requirements on the antenna
are often given by means of the minimum antenna diameter. The meaning of such a requirement is "that the antenna
gain pattern shall be compliant with a reference pattern or mask that includes the nominal antenna diameter as a
parameter". The nominal diameter is a means for specifying and classifying antennas and in an easy way, but the actual
antenna diameter may be different from it, or the antenna might not be circular. The concept of gain pattern definition
with nominal antenna diameter is applied in the present document.

Besides the concept of ODU, IDU, IFL and optionally multi-switches, new concepts with different allocation of
functionality exist. With channel stacking or SatCR, frequency channels are re-arranged by the ODU or an additional
unit, so that all relevant channels can be carried on a single coaxial cable. IDUs or additional cables are connected by
simple splitters. With Sat>IP, the ODU or an additional device performs demodulation and conversion to video over
Internet Protocol. Common connected devices including tablet computers can be used to watch broadcast television
inside a home network. Another concept applies optical fibre to carry signals between ODU and multi-switches. In
conjunction with these and further concepts, the same requirements on the ODU characteristics exist.
The present document consists of multiple parts that apply to different kinds of equipment units, including ODUs for
specific frequency bands and IDUs.

1 Scope
The present document applies to ODUs for satellite broadcast reception from geostationary satellites in the frequency
band 10,7 GHz to 12,75 GHz. An ODU receives electromagnetic waves from a satellite. It amplifies the receive signal
at low noise, converts it to a lower frequency band and makes it available to the IDU on an interface.
Part of the IDU functionality may be integrated with the ODU. In that case the present document applies only to the
ODU functionality that is defined above.
The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the
efficient use of radio spectrum in order to avoid harmful interference.

antenna is a parabolic reflector antenna with offset feed. In that case the feed horn is often integrated with the LNB into
one unit called Low Noise Block converter with Feed (LNBF). The IDU demodulates one of the carriers,
de-multiplexes the retrieved bit stream and decodes digital audio video and audio for display on a TV screen. Common
terms for the IDU are set-top box or satellite receiver. IDUs may contain a hard disk for recording programs. An IDU
may be capable of processing multiple carriers for direct viewing and recording. The IDU functionality may be
integrated into a TV set. Typically, the satellite transmits two electromagnetic waves with orthogonal polarization at the
same time. In case the satellite transmits a large frequency band, it is divided up for frequency conversion with different
local oscillator frequencies. The IDU selects by control signals which polarization and frequency band the ODU
provides on the IFL. An ODU may work with multiple IDUs or IDUs with multiple tuners via separate IFLs. Multi-
switches connected to an ODU allow connecting a large number of IDUs.
Frequency bands are re-used by satellites on different orbital positions of the Geostationary Orbit arc. Discrimination
between signals from wanted and adjacent orbital positions is provided by the directivity of the ODU antenna. The
actually required discrimination depends on the specific scenario of satellite spacing and Equivalent Isotropically
Radiated Power (EIRP), as well as on the robustness of the wanted signals. Moreover, a certain on-axis gain is required
for receiving the wanted signals with the target availability. In general, a larger antenna provides better discrimination
and gain, but on the other hand small antennas are better accepted by users and the public. Requirements on the antenna
are often given by means of the minimum antenna diameter. The meaning of such a requirement is "that the antenna
gain pattern shall be compliant with a reference pattern or mask that includes the nominal antenna diameter as a
parameter". The nominal diameter is a means for specifying and classifying antennas and in an easy way, but the actual
antenna diameter may be different from it, or the antenna might not be circular. The concept of gain pattern definition
with nominal antenna diameter is applied in the present document.

Besides the concept of ODU, IDU, IFL and optionally multi-switches, new concepts with different allocation of
functionality exist. With channel stacking or SatCR, frequency channels are re-arranged by the ODU or an additional
unit, so that all relevant channels can be carried on a single coaxial cable. IDUs or additional cables are connected by
simple splitters. With Sat>IP, the ODU or an additional device performs demodulation and conversion to video over
Internet Protocol. Common connected devices including tablet computers can be used to watch broadcast television
inside a home network. Another concept applies optical fibre to carry signals between ODU and multi-switches. In
conjunction with these and further concepts, the same requirements on the ODU characteristics exist.
The present document consists of multiple parts that apply to different kinds of equipment units, including ODUs for
specific frequency bands and IDUs.

1 Scope
The present document applies to ODUs for satellite broadcast reception from geostationary satellites in the frequency
band 10,7 GHz to 12,75 GHz. An ODU receives electromagnetic waves from a satellite. It amplifies the receive signal
at low noise, converts it to a lower frequency band and makes it available to the IDU on an interface.
Part of the IDU functionality may be integrated with the ODU. In that case the present document applies only to the
ODU functionality that is defined above.
The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the
efficient use of radio spectrum in order to avoid harmful interference.
