EN 300 829 V1.1.1 (1998-03)61ScopeThe present document covers the assessment of Inmarsat-C Global Maritime Distress and Safety System (GMDSS) andEnhanced Group Call (EGC) Ship Earth Stations, as defined by the International Maritime Organization (IMO) to beused for Low Bit Rate Data Communications (LBRDC) in the GMDSS, in respect of ElectroMagnetic Compatibility(EMC).Technical specifications related to the antenna port and emissions for the enclosure port of the radio equipment arefound in the related product standard ETS 300 460 [11] for the effective use of the radio spectrum.The present document specifies the applicable EMC tests, the test methods, the limits and the minimum performancecriteria for Ship Earth Stations for the maritime mobile service operating in the Maritime Mobile Satellite Service(MMSS) bands.The ElectroMagnetic Environment used in the present document to develop the technical specifications encompasses theElectroMagnetic Environment on board ships as identified in EN 60945 [13].The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus in maritimeenvironments. The levels do not cover extreme cases which may occur in any location, but have a low probability ofoccurrence.Compliance of radio equipment to the requirements of the present document does not signify compliance to anyrequirements related to the use of the equipment (i.e. licensing requirements).Compliance to the present document does not signify compliance to any safety requirements. However, it is theresponsibility of the assessor of the equipment that any observations regarding apparatus becoming dangerous or unsafeas a result of the application of the tests defined in the present document, are recorded in the test report.The present document is based on the consideration and guidance as given in ETR 238 [12].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]CISPR 16-1: "Specification for radio disturbance and immunity measuring apparatus and methods- Part 1: Radio disturbance and immunity measuring apparatus".[2]EN 55022 (1994): "Limits and methods of measurement of radio disturbance characteristics ofinformation technology equipment".[3]EN 61000-4-2: "Electromagnetic compatibility (EMC) - Part 4: Testing and measurementtechniques - Section 2: Electrostatic discharge immunity test".[4]EN 61000-4-11: "Electromagnetic compatibility (EMC) - Part 4: Testing and measurementtechniques - Section 11: Voltage dips, short interruptions and voltage variations immunity tests".SIST EN 300 829:2000

Thefrequency of the test voltage shall be 50 Hz ± 1 Hz.The normal test voltage for equipment to be connected to a battery, shall be the nominal voltage of the battery (12 V,24 V etc.). For operation from other power sources, the normal test voltage shall be declared by the manufacturer.The test configuration shall be as close as possible to normal intended use.SIST EN 300 829:2000
EN 300 829 V1.1.1 (1998-03)9If the equipment is part of a system, or can be connected to ancillary equipment, then it shall be acceptable to test theequipment while connected to the minimum representative configuration of ancillary equipment necessary to exercisethe ports.Ports which in normal operation are connected shall be connected to an ancillary equipment or to a representative pieceof cable correctly terminated to simulate the input/output characteristics of the ancillary equipment. RF input/outputports shall be correctly terminated.If the equipment has a large number of ports, then a sufficient number shall be selected to simulate actual operationconditions and to ensure that all the different types of termination are tested.Ports which are not connected to cables during normal intended operation, e.g. service connectors, programmingconnectors, temporary connectors etc. shall not be connected to any cables for the purpose of EMC testing. Wherecables have to be connected these ports, or interconnecting cables have to be extended in length in order to exercise theEUT, precautions shall be taken to ensure that the evaluation of the EUT is not affected by the addition or extension ofthese cables.The test conditions, test configuration and mode of operation shall be recorded in the test report.4.1.1Emission testsThis subclause defines the test conditions and configurations for the emission tests as follows:-the measurement shall be made in the operation mode producing the largest emission in the frequency band beinginvestigated consistent with normal applications;-an attempt shall be made to maximize the detected radiated emission for example by moving the cables of theequipment.For the purpose of the emission tests, the EUT may be provided with a test facility to activate the transmitter withoutreception of enabling signals from the STE.The details of the test facility shall be recorded in the test report.4.1.2Immunity testsThis subclause defines the test conditions and configurations for the immunity tests as follows:-the measurement shall be made in the mode of operation as required in subclause 4.1.2.1;-for the immunity tests of ancillary equipment without separate pass/fall criteria, the receiver or transceivercoupled to the ancillary equipment shall be used to judge whether the ancillary equipment passes or fails.4.1.2.1Mode of operationFor the immunity tests of transmitters, the transmitter shall be operated at normal RF output power, modulated withnormal modulation.For the immunity test of receivers, the wanted input signal coupled to the receiver shall be modulated with normalmodulation.4.1.2.2Special Test EquipmentThe Special Test Equipment (STE) shall be supplied by the manufacturer or system provider. Since this test equipmentwill be specific for the particular system, it is not possible to provide detailed specifications in the present document.However the following requirements apply:-STE shall simulate the satellite signal, thus enabling the ship earth station to transmit to allow measurements oftransmission parameters;-any specification of the STE which may have direct or indirect effects on any specification of the presentdocument shall be clearly stated by the manufacturer;SIST EN 300 829:2000
EN 300 829 V1.1.1 (1998-03)10-the STE shall prevent any radiation of signals, and it shall be certified by the system operator to be suitable forsuch purpose;-when using the STE it shall be ensured that no transmission to the satellite occurs.The details of the STE shall be recorded in the test report.4.2Narrowband responses on receivers and receivers oftransceiversResponses on receivers or receivers of transceivers occurring during the test at discrete frequencies which are narrowband responses (spurious responses) are identified by the following method.If an unwanted signal causes the EUT to fail the performance check it is necessary to establish whether the failure is dueto a narrow band response or to wide band phenomena.Taking the initial test frequency as reference the procedure is repeated with an increase of the unwanted signal frequencyby an amount equal to twice the bandwidth of the IF filter, as declared by the manufacturer. For the purpose of thepresent document, in the absence of a narrow IF filter bandwidth declared by the manufacturer, the IF bandwidth shallbe taken as 5 kHz.If the performance check is successful, then the response is considered to be a narrow band response.If the performance check still fails, the test is repeated with the frequency of the unwanted signal decreased by the sameamount.If the performance check is successful, then the response is considered to be a narrow band response.If the performance check still fails, this may be due to the fact that the offset has made the frequency of the unwantedsignal correspond to the frequency of another narrow band response.Therefore, taking the initial test frequency as a reference the procedure is repeated with an increase of the unwantedsignal frequency by two and one half times the bandwidth referred to in the third paragraph of this subclause.If the performance check is successful, the response is considered to be a narrow band response. If the performancecheck still fails, the test is repeated with the frequency of the unwanted signal decreased by two and one half times thebandwidth referred to in the third paragraph of this subclause.If the performance check still fails, the phenomenon is considered wideband and therefore an EMC problem and theequipment fails the test.All narrow band responses shall be disregarded.5Performance assessment5.1GeneralThe manufacturer shall supply the following information to be recorded in the test report:-the intended functions of the radio equipment which shall be in accordance with the documentationaccompanying the equipment;-the primary functions of the radio equipment to be tested during and after the EMC testing;-the characteristics of the signal used for testing (random bit stream, message format, etc.) and details of thenecessary test equipment required to enable the assessment of the EUT;SIST EN 300 829:2000
EN 300 829 V1.1.1 (1998-03)11-the method to be used to verify that a communications link is established and maintained;-the ancillary equipment to be combined with the radio equipment for testing (where applicable);-an exhaustive list of all ports, with the maximum cable lengths allowed, classified as either power, signal, controlor antenna.
