Foreword
This European Standard (Telecommunications series) has been produced by ETSI Technical Committee
Electromagnetic compatibility and Radio spectrum Matters (ERM).
The present document is based upon the Generic Standards EN 50081-1 and EN 50082-1. Other standards cover radio
communications equipment not listed in the scope of the present document.
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 83/189/EEC (as amended) laying down a procedure for the provision of information in the field
of technical standards and regulations.
The present document, together with ETS 300 733 or ETS 300 734 as appropriate, is intended to become a Harmonized
Standard, the reference of which will be published in the Official Journal of the European Communities referencing the
Council Directive on the approximation of the laws of the Member States relating to electromagnetic compatibility ("the
EMC Directive") (89/336/EEC as amended).
Technical specifications relevant to the EMC Directive are given in annex A.

1 Scope
The present document covers the assessment of Mobile Earth Stations (MES) used within Satellite Personal
Communications Networks (S-PCN), and ancillary equipment in respect of ElectroMagnetic Compatibility (EMC).
Technical specifications related to the antenna port and emissions from the enclosure port of the equipment are not
included in the present document. Such specific technical specifications are found in the relevant product ETS.
The present document specifies the applicable EMC tests, the test methods, the limits, and the minimum performance
criteria for digital radio equipment as defined in annex B, operating in the frequency ranges 1,6/2,4 GHz and 2 GHz,
and for the associated ancillary equipment.
In addition to the technical specification of the present document, there may be published in the Official Journal of the
European Communities (OJEC) references to Harmonized EMC standards that apply to the products covered by the
present document in their own right, for example EN 61000-3-2 and EN 61000-3-3 (power frequency harmonics and
voltage fluctuation).
The environment classification used in the present document refers to the environment classification used in the Generic
Standards EN 50081-1 [1] and EN 50082-1 [2], except the vehicular environment class which refers to ISO 7637–1 [3].
The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus at residential,
commercial, light industrial and vehicular environments. The levels, however, do not cover extreme cases which may
occur in any location but with a low probability of occurrence.
The present document may not cover those cases where a potential source of interference, which is producing
individually repeated transient phenomena, or a continuous phenomenon, is permanently 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.
For a multimode radio station, the present document only applies to the radio station when operated in the S-PCN mode.
Compliance of S-PCN Mobile Earth Stations (MES) radio equipment to the requirements of the present document does
not signify compliance to any requirements related to the use of the equipment (i.e. licensing requirements).
The present document is based on the considerations and guidance given in ETR 238 [13].

- the equipment is intended for use in conjunction with a MES to provide additional operational and/or control
features to the MES (e.g. to extend control to another position or location); and
- the equipment cannot be used on a stand alone basis to provide MES user functions independently of a MES; and
- the absence of the ancillary equipment does not inhibit the operation of the MES.

4 General test conditions
4.1 Test conditions
For MESs with ancillary equipment and/or various ports, the number of test configurations shall be determined. The
assessment shall include sufficient representative configurations of the MES 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 MES with the selected configuration of ancillary
equipment.
The equipment shall be tested under conditions which are within the applicant's declared range of humidity,
temperature, and supply voltage.
The EUT operational frequencies used during the test, shall be recorded in the test report.
The test conditions shall be recorded in the test report.
The test configuration shall be as close to normal intended use as possible, and shall be recorded in the test report.
For testing and if physically separated from the MES, any voltage converter shall form part of the EUT.
Whenever the Equipment Under Test (EUT) is provided with an integral antenna, the EUT shall be tested with the
antenna fitted in a manner typical of normal intended use.
For MES for which connection to a host equipment is necessary to offer additional functionality, the test configuration
shall be as defined in subclause 5.4.
4.2 Arrangements for tests
In order to measure the system emission and electromagnetic immunity under operational conditions, proper
arrangements shall be provided (by the applicant), e.g.:
a) a Special Test Equipment (STE) to put the MES terminal in its normal operating mode, and providing the MES
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) a specific Quality of Transmission Measurement Apparatus (QTMA).
EXAMPLE: The quality of transmission can concern:
- the audio signal;
- the BER;

- the message throughput;
- the continuity of the communication link; or
- a combination of them.
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. Signal level adjustment may be performed by
adjustment of the test transmitter output level such that the received signal level is as close to the normal operation
signal level as possible. This signal level should be sufficient to avoid the broad band noise from the power amplifiers
generating the EMC disturbance 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 (STE), the QTMA and the source of the wanted input signal shall be located outside the
test environment. Adequate measures shall be ta
