FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international co-operation on all questions concerning standardization in the electrical and electronic
fields. To this end and in addition to other activities, the IEC publishes International Standards. Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt
with may participate in this preparatory work. International, governmental and non-governmental organizations
liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International
Organization for Standardization (ISO) in accordance with conditions determined by agreement between the
two organizations.
2) The formal decisions or agreements of the IEC on technical matters, express as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the
form of standards, technical reports or guides and they are accepted by the National Committees in that
sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
Attention is drawn to the possibility that some of the elements of this International Standard may be the
6)
subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 1319-1 has been prepared by IEC technical committee 84:
Equipment and systems in the field of audio, video and audiovisual engineering.
The text of this standard is based on the following documents:
DIS Report on voting
84/420/FDIS 84/447/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
Annex A is for information only.

INTRODUCTION
Informal interconnection standards for satellite receiving equipment exist in Europe, North
America and Japan, and they are not sufficiently similar to allow one common IEC standard to
be achieved. Consequently, it has proved necessary to produce three standards:
Interconnections of satellite receiving equipment - Part 1: Europe
IEC 1319-1,
Interconnections of satellite receiving equipment - Part 2: Japan
IEC 1319-2,
Interconnections of satellite receiving equipment - Part 3: North America

4 Interface requirements for polarizers and polarswitchers
4.1 Mechanical polarizers (optional)
Three output terminals shall be provided, with the corresponding signals.
0 V
a) Common reference (ground):
5,0 V (±10 %)
b) Voltage:
0,2 A continuous
Load current:
0,5 A maximum during 1 s
The control signal is a pulse width modulated signal with the following characteristics:
c)
TTL levels (see 3.6)
Voltages:
17 ms to 21 ms
Pulse repetition rate:
0,8 ms to 2,2 ms
Pulse duration:
positive going pulse
Pulse polarity:
The waveguide probe shall be able to rotate through an angle in excess of 135° without
mechanical blocking.
NOTE — A minimum rotation angle of 135° is needed for polarizers suitable for the four polarization types V,
H, R and L. Usually the antenna probe is placed behind a PTFE strip in a round waveguide. The PTFE strip
should be oriented parallel to the H direction, so that the correspondence between rotation angle and
polarization type is:
R= 45° V= 90° L= 135°
H= 0°
The other angles can be derived from the specified values by linear interpolation.
A pulse duration in the range of 0,8 ms to 1,2 ms shall correspond to horizontal (H)
polarization.
A pulse duration in the range of 1,6 ms to 2,2 ms shall correspond to vertical (V) polarization.
NOTE — These ranges take into account mechanical tolerances in the polarizer and in the mounting of the
antenna.
If the pulse is generated digitally, the change in pulse duration required to produce a rotation of
135° shall have a resolution of at least 1 part in 128 of the maximum duration of the pulse.
The control pulse train may be continuous, or active only during change commands. In the
latter case, it is essential that the 5 V supply voltage line is activated (and deactivated) with the
pulse already (or still) in existence. The total duration of the active pulse train shall be at least
1,5 s.

1319-1 © IEC:1995 – 21 –
4.2 Magnetic polarizers (using the Faraday effect)
In order to ensure a constant magnetic field strength over a wide temperature range, a
symmetrical constant current supply is preferred.
4.2.1 Polarizers for two orthogonal polarizations
The constant current supply shall have a range of at least ±50 mA, and shall be capable of
passing 50 mA into a load resistance of 100 S2.
4.2.2 Polarizers for four polarizations
The constant current supply shall have a range of at least +100 mA to –50 mA, and shall be
capable of passing +100 mA and –50 mA into a load resistance of 100 S2.
To compensate for the considerable differences in the sensitivity (angle of rotation for a given
in 256 of the maximum
current) of different types of polarizers, a resolution of at least 1 pa rt
rotation angle is recommended if the current is controlled digitally.
The above-mentioned requirements are based on a maximum polarizer sensitivity corres-
ponding to a 45° rotation and a current of 25 mA. Due to the variation of sensitivity of some
types of polarizers to carrier frequency, it is recommended that the individual current value for
each program position should be stored in the memory of the receiver.
4.3 Polarswitchers
In the case of low-cost satellite reception units for satellites using only one microwave band, it
is quite popular to combine the LNB with a unit switching between H and V polarizations. In this
case the H/V status is controlled in the same way as the band-switch of dual-band LNBs.
ical or right-hand circular
11,5 V to 14,0 V corresponds to ve rt
16,0 V to 19,0 V corresponds to horizontal or left-hand circular
The above-mentioned values apply to the input of the LNB or polarswitcher (for details see
5.2.2 and 5.3).
