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

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

For the purpose of this part of IEC 1319, the following special terms and abbreviations are

used:
Digital Satellite Radio.
3.1 DSR:
Electromagnetic wave with vertically oriented electrical field
3.2 vertical (V) polarization:
vector.
As in 3.2, but with horizontal orientation.
3.3 horizontal (H) polarization:

3.5 right-hand (R) polarization:
Voltages corresponding to logic 0 and logic 1 for 74-series TTL integrated
3.6 TTL levels:

for storing data on the optimum adjustment of the receiver, and often of the associated

equipment, for that emission.

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:

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).
