1 Scope
This European Telecommunication Standard (ETS) covers the assessment of Very Small Aperture
Terminals (VSAT) and Satellite News Gathering (SNG) Transportable Earth Stations (TESs)
communication equipment in respect of Electromagnetic Compatibility (EMC). Technical specifications
related to the antenna port and emissions from the enclosure port of the equipment, for frequencies
above 1 000 MHz, are not included in this ETS. Such specific technical specifications are found in the
relevant product standards for the effective use of the radio spectrum.
This ETS specifies the applicable EMC tests, the limits, and the minimum performance criteria for the
following Earth Stations (ES) as defined in annex B.
The environment classification used in this ETS refers to the environment classification used in the
Generic Standards EN 50081-1 [1] and EN 50082-1 [2].
The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus in
residential, commercial and light industrial environments. The levels, however, do not cover extreme
cases which may occur in any location but with a low probability of occurrence.
This ETS may not cover those cases where a potential source of interference which is producing
individually repeated transient phenomena or a continuous phenomenon is present, e.g. a radar or
broadcast site in the near vicinity. In such a case it may be necessary to use special protection applied to
either the source of interference, or the interfered part or both.
Compliance of VSAT equipment to the requirements of this ETS does not imply compliance to any
requirement related to the use of the equipment (e.g. licensing requirements).

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this ETS, the following definitions apply:
ancillary equipment: An equipment used in connection with an ES is considered as ancillary if the
following three conditions are met:
- the equipment is intended for use in conjunction with an ES to provide additional operational and/or
control features (e.g. to extend control to another position or location); and
- the equipment cannot be used on a stand alone basis to provide user functions independently of an
ES; and
- the absence of the equipment does not inhibit the operation of the ES.
carrier-on state: A transmit ES is in this state when it is authorized to transmit, and when it transmits a
signal, either authorized by a Centralized Control and Monitoring Function (CCMF) when designed for
unattended operation or by local control when designed for attended operation.
carrier-off state: A transmit ES is in this state when it is authorized to transmit, and when it does not
transmit any signal, either authorized by a CCMF when designed for unattended operation or by local
control when designed for attended operation.
NOTE: The existence of a carrier-off state depends on the system of transmission used. For
VSATs designed for continuous transmission mode there may be no carrier-off state.
enclosure port: The physical boundary of the apparatus through which an electromagnetic field may
radiate or impinge (figure 1).
manufacturer (supplier): The legal entity responsible under the terms of the Council Directive,
89/336/EEC [3], for placing the product on the market.
port: A particular interface of the specified apparatus with the external electromagnetic environment
(figure 1).

4 General test conditions
4.1 Test conditions
For Earth Stations with or without ancillary equipment, and/or various terrestrial ports, the number of test
configurations shall be determined. The assessment shall include sufficient representative configurations
of the ES to adequately exercise the equipment. These configurations shall be recorded in the test report.
In the following clauses, the Equipment Under Test (EUT) is the ES with the selected configuration of
ancillary equipment.
The equipment shall be tested under conditions which are within the manufacturers declared range of
humidity, temperature, and supply voltage.
The test conditions shall be recorded in the test report.
4.2 Arrangements for tests
In order to measure the unwanted emissions and electromagnetic immunity under operational conditions,
the following arrangements shall be provided by the manufacturer:
a) a special test equipment to put the ES terminal in its normal operating mode, and providing the ES
with a receive signal to emulate the operational conditions of reception. This equipment shall control
the EUT, when it is capable of transmission, so that it switches between the transmission disabled,
carrier-on and carrier-off states;
b) the specific Quality of Transmission Measurement Apparatus (QTMA).
For the measurement of the quality of transmission a communications link shall be established and the
wanted input signal shall be applied to the Radio Frequency (RF) input of the receiver via the antenna. For
tests on the receiver, the level of the signal received from the test transmitter shall be as close as possible
to the normal operation level of the EUT receiver. Care should be taken to avoid the broad band noise
from the power amplifier of the test transmitter from influencing the measurement.
Adequate measures shall be taken to avoid the effects of the unwanted signal on the measuring
equipment.
The special test equipment, the QTMA and the source of the wanted input signal shall be located outside
the test environment. Adequate measures shall be taken to protect them from the effects of all the
radiated fields within the test environment.

5 Performance assessment
5.1 General
The manufacturer shall, at the time of submission of the equipment for test, declare the intended use of
the equipment, and provide full and complete documentation necessary for user operation, testing and
evaluation purposes. This documentation shall include, but not be limited to:
- the ranges of the operational parameters, e.g. the power delivered to the antenna, the frequency
ranges;
- an exhaustive list of ports, classified as either power or signal/control. Power ports shall further be
classified as AC or DC power;
- the ancillary equipment to be combined with the ES for testing, if applicable;
- the user-control functions that are required for normal operation;
- the minimum quality of transmission, and the method to be used to assess it.
This information shall be in accordance with the documentation accompanying the equipment.
All this information shall be recorded in the test report.
5.2 Equipment configuration(s)
For radiation measurements in carrier-on state, the ES shall be put in a continuous transmit mode or to
the maximum burst rate where applicable. The ES shall be operated at the highest normal operating
Equivalent Isotropically Radiated Power (EIRP) or, if that is the maximum attainable, then 3 dB below
such maximum.
A suggested test configuration is shown in figure 2.
