ETSI ETSI EN 303 372-1 V1.1.1 (2016-08) 6 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.5], which is the predecessor of the Radio Equipment Directive, 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.

ETSI ETSI EN 303 372-1 V1.1.1 (2016-08) 7 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 conventional ODU functionality. 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. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

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.5], which is the predecessor of the Radio Equipment Directive, 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
conventional ODU functionality.
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.

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.

6 Draft ETSI EN 303 372-1 V1.1.0 (2016-01)
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 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.5], which is the predecessor of the Radio Equipment Directive, 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 fiber 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.

4 Technical requirements specifications
4.1 Environmental profile
The technical requirements of the present document apply under the environmental profile for operation of the
equipment, which shall be declared by the supplier. The equipment shall comply with all the technical requirements of
the present document at all times when operating within the boundary limits of the declared operational environmental
profile.
4.2 Equipment capabilities
The technical requirements of the present document apply under the capabilities of the equipment, which shall be
declared by the supplier. The equipment shall comply with all the technical requirements of the present document at all
times when operating within the boundary limits of the declared equipment capabilities.
Equipment capabilities comprise the following characteristics:
• Receive frequency band
• Polarization states
• Local oscillator frequency
• Nominal antenna diameter
• Specific satellite network - if applicable
An ODU might be capable of receiving multiple frequency bands. The local oscillator frequency and the polarization
states may be different in each frequency band. The declaration shall include all combinations of frequency band,
polarization states and local oscillator frequency.
Polarization state can take the values horizontal linear, vertical linear, left hand circular and right hand circular. An
ODU may receive multiple states in one frequency band.
If an ODU is designed for a specific satellite network, then certain requirements do not apply.
4.3 Conformance requirements
4.3.1 Radiation from the ODU
Specification 1: Unwanted radiation including Local Oscillator (LO) leakage radiated from the antenna
Purpose:
To limit the unwanted radiation level from the outdoor unit in order to protect adjacent satellites that use different
frequency bands and are located near-by.
The EIRP of the unwanted radiation, including the LO frequency as well as its second harmonic, transmitted in the
antenna axis (or boresight) direction, shall not exceed the following limits:
• −60 + dBm in a 120 kHz bandwidth at the fundamental frequency of the LO u
• −50 + dBm in a 120 kHz bandwidth at the second harmonic of the LO u
• −60 + dBm in any other 120 kHz bandwidth u
where =20 log . is the nominal antenna diameter, is the wave length. u
This specification applies to the frequency range from 2,5 GHz to 25 GHz.
NOTE 1: These limits are derived from those in ETSI ETS 300 784 [i.2]. Here EIRP is used instead of power at the
antenna flange, because an antenna flange may not be present. is the upper bound for the antenna on-u
axis gain, which corresponds to 100 % efficiency.

Specification 2: Radiation from the outdoor unit (EIRP)
Purpose:
To limit unwanted radiation level from the outdoor unit in order to protect other systems.
The EIRP of unwanted signals radiated by the outdoor unit within the band from 30 MHz to 25 GHz, shall not exceed
the following values measured in any 120 kHz bandwidth (see CISPR No. 16-1 [i.4]):
• 20 dBpW in the range 30 MHz to 960 MHz;
• 43 dBpW in the range from 960 MHz to 2,5 GHz;
• 57 dBpW in the range from 2,5 GHz to 25 GHz.
The lower limits apply at the transition frequency.
This specification applies for all off-axis angles greater than 7°.
NOTE 2: EIRP limits are in accordance with CENELEC EN 50083-2 [i.3].
