Other standards coverradio 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 issuedunder Council Directive 83/189/EEC (as amended) laying down a procedure for the provision of information in the fieldof technical standards and regulations.The present document, together with ETS 300 721, is intended to become a Harmonized Standard, the reference ofwhich will be published in the Official Journal of the European Communities referencing the Council Directive on theapproximation 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.National transposition datesDate of adoption of this EN:6 February 1998Date of latest announcement of this EN (doa):31 May 1998Date of latest publication of new National Standardor endorsement of this EN (dop/e):30 November 1998Date of withdrawal of any conflicting National Standard (dow):30 November 1998SIST EN 300 832:2000



EN 300 832 V1.1.1 (1998-03)61ScopeThe present document covers the assessment of Mobile Earth Stations (MESs) and ancillary equipment in respect ofElectroMagnetic Compatibility (EMC).Technical specifications related to the antenna port and emissions from the enclosure port of the equipment are notincluded in the present document. Such specific technical specifications are found in the relevant product standard.The present document specifies the applicable EMC tests, the test methods, the limits and the minimum performancecriteria for MESs providing Low Bit Rate Data Communications (LBRDC) using satellites in Low Earth Orbit (LEO)and operating in frequency bands below 1 GHz, as defined in ETS 300 721 [3], and ancillary equipment.In addition to the technical specification of the present document, there may be published in the Official Journal of theEuropean Communities (OJEC) references to Harmonized EMC standards that apply to the products covered by thepresent document in their own right, for example, EN 61000-3-2 and EN 61000-3-3 (power frequency harmonics andvoltage fluctuation).The environment classification used in the present document refers to the environment classification used in the GenericStandards EN 50081-1 [1] and EN 50082-1 [2], except the vehicular environment class which refers to ISO 7637-1 [4]and ISO 7637-2 [5].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 mayoccur 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 producingindividually repeated transient phenomena, or a continuous phenomenon, is permanently present, e.g. a radar orbroadcast site in the near vicinity. In such a case it may be necessary to use special protection applied to either thesource of interference, or the interfered part, or both.Compliance of a MES to the requirements of the present document does not signify compliance to any requirementsrelated to the use of the equipment (i.e. licensing requirements).The present document is based on the considerations and guidance given in ETR 238 [14].2ReferencesReferences may be made to:a)specific versions of publications (identified by date of publication, edition number, version number, etc.), inwhich case, subsequent revisions to the referenced document do not apply; orb)all versions up to and including the identified version (identified by "up to and including" before the versionidentity); orc)all versions subsequent to and including the identified version (identified by "onwards" following the versionidentity); ord)publications without mention of a specific version, in which case the latest version applies.A non-specific reference to an ETS shall also be taken to refer to later versions published as an EN with the samenumber.[1]EN 50081-1 (1992): "Electromagnetic compatibility - Generic emission standard - Part 1:Residential, commercial and light industry".[2]EN 50082-1 (1993): "Electromagnetic compatibility - Generic immunity standard - Part 1:Residential, commercial and light industry".SIST EN 300 832:2000

The assessment shall include sufficient representative configurations of the MES to adequately exercisethe 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 ancillaryequipment.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 theantenna 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 configurationshall be as defined in subclause 5.4.4.2Arrangements for testsIn order to measure the system emission and electromagnetic immunity under operational conditions, properarrangements have to 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 MESwith 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 carrier-on and carrier-off states;b)a specific Quality of Transmission Measurement Apparatus (QTMA).EXAMPLE:The quality of transmission can concern:- the Bit Error Ratio (BER);- the message throughput;- the continuity of the communication link; or- a combination of them.SIST EN 300 832:2000



EN 300 832 V1.1.1 (1998-03)10For the measurement of the quality of transmission, a communications link shall be established and the wanted inputsignal shall be applied to the Radio Frequency (RF) input of the receiver. Signal level adjustment may be performed byadjustment of the test transmitter output level such that the received signal level is as close to the normal operationsignal 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 STE, the QTMA and the source of the wanted input signal shall be located outside the test environment. Adequatemeasures shall be taken to protect them from the effects of all the radiated fields within the test environment.For the quality of transmission measurement, the MES may be put in a specific mode for that test where the receiveddata are looped back to the transmitter.4.3RF connection of test signalsWhere the equipment incorporates an external antenna connector and when agreed by the applicant, the antenna shall beremoved and the wanted signal to establish communications shall be delivered through that connector by a coaxial cable.Adequate measures shall be taken to minimize the effect of unwanted currents on the external conductor of the coaxialcable at the point of entry to the equipment. Adequate measures shall also be taken to avoid the effect of the unwantedsignal on the measuring equipment.Where the equipment incorporates an external antenna connector, the applicant may consider it as an integral antennafor the purpose of this test.The test system shall be located outside of the test environment.Where the equipment does not incorporate an external RF connector, the wanted signal to establish communicationsshall be delivered from the equipment to an antenna located within the test environment. Adequate measures shall betaken to protect the measuring equipment from the effect of all the radiated fields within the test environment.4.4Exclusion bandThere shall be no immunity tests for the transmitter parts of MESs within the tran
