EN 300 830 V1.1.1 (1998-03)61ScopeThe present document provides ElectroMagnetic Compatibility (EMC) specifications for the standardization of ReceiveOnly Mobile Earth Stations (ROMES). Specifications relating to emissions from the antenna port and emissions fromthe enclosure port of the ROMES (figure 1) are not included in the present document. Specifications for emissions fromthe antenna port and from the enclosure port of the ROMESs are included in ETS 300 487 [15].The present document applies to ROMESs which operate in the Land Mobile Satellite Service (LMSS) space to earthbands, 1 525 MHz to 1 544 MHz and 1 555 MHz to 1 559 MHz, allocated by the ITU Radio Regulations [1]. TheROMESs operate as part of a satellite system providing one way data communications.ROMESs can have several configurations, including:-portable equipment;-fixed equipment;-a number of modules including a display/control interface to the user.The present document specifies the applicable EMC tests, their method of measurement, the limits and the minimumperformance criteria for ROMESs. The performance criteria used in the present document requires that the satellitecommunications system of which the ROMES is a part provides reliable delivery of data or messages.The environment classification used in the present document refers to the environment classification used in GenericStandards EN 50081-1 [2] and EN 50082-1 [3], except the vehicular environment class which refers to ISO 7637-1 [11]and ISO 7637-2 [12].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 anylocation 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 phenomena is permanently present, e.g. a radar or broadcastsite in the near vicinity. In such a case it may be necessary to use special protection applied to either the source ofinterference or the interfered part or both.Compliance of radio equipment to the requirements of the present document does not signify compliance to anyrequirements related to spectrum management.Compliance to the present document does not signify compliance to any safety requirements. However, it is theresponsibility of the assessor of the equipment to ensure that any observation regarding the equipment becomingdangerous or unsafe as a result of the application of the tests of the present document should be recorded.In addition to the technical specifications of the present document, there may be published in the Official Journal of theEuropean Community references to other Harmonized EMC standards that apply to the products covered by the presentdocument in their own right.The present document is based on the considerations and guidance given in ETR 238 [16].SIST EN 300 830:2000

The tests shall be carried out at a point within the specified normal operatingenvironmental range and at the rated supply voltage for the equipment.The test conditions and configuration shall be as close to normal intended use as possible and shall be recorded in thetest report.4.2Normal test modulationThe test modulation signal to be used for the calling function shall be a signal representing selective messages generatedby a signal generator. The signal generator may be supplied by the manufacturer.4.3Arrangements for test signals at the input of a ROMESThe manufacturer may, at the time of submitting the ROMES for testing, supply, if necessary, a test fixture and amessage generator to generate the wanted input signal.The source of the wanted input signal, modulated with normal test modulation (subclause 4.2), shall be located outsidethe test environment and the signal level used shall be chosen to be a value significantly above the threshold sensitivitybut below the overload characteristics of the ROMES (the threshold sensitivity and overload characteristic shall bespecified by the manufacturer). Adequate measures shall be taken to protect the measuring equipment from the effect ofthe test environment.Where the receiver incorporates a Radio Frequency (RF) antenna connector, the RF signal source shall be coupled to theinput of the ROMES via a shielded transmission line such as a coaxial cable.Where the ROMES does not incorporate an RF connector, the RF signal source shall be presented to the ROMES fromanother antenna located within the test environment. This antenna shall be coupled to the RF signal source via anappropriate attenuate.4.4Arrangements for test signals at the output of the ROMESFor the performance check before and after the test it shall be possible to assess the performance of the ROMES fromthe presented messages and/or the call received alert signal(s) of the ROMES.During the spot frequency test of the radio frequency immunity test (subclause 9.2) the call received alert signal outputof the ROMES shall be coupled to the outside of the test environment and it shall be possible to assess the performanceof the equipment from the call received alert signal(s) of the ROMES.SIST EN 300 830:2000



EN 300 830 V1.1.1 (1998-03)104.5Exclusion bands for ROMESExclusion bands are determined frequency bands for which the Equipment Under Test (EUT) is excluded from RFimmunity tests.There are no exclusion bands for ROMES as the operating frequency of a ROMES falls outside the range of frequenciesspecified for RF immunity tests.4.6Narrow band responses on ROMESNo immunity tests shall be carried out on frequencies of identified unwanted narrowband responses (spurious responses)of the receiver. These narrowband responses (spurious responses) are identified by the following method.If during the test the unwanted signal causes a non acceptable degradation in performance (subclause 6.2), it is necessaryto establish whether this is due to a narrow band response or to a wideband phenomena. Therefore, the unwanted signalfrequency is increased by an amount equal to twice the nominal bandwidth of the receiver pre-demodulation filter, asdeclared by the manufacturer. The test is repeated with the frequency of the unwanted signal decreased by the sameamount.If the degradation in performance becomes acceptable again (subclause 6.2), then the response is considered to be anarrow band response.If the degradation in performance is still not acceptable, this may be due to the fact that the offset has made thefrequency of the unwanted signal correspond to the frequency of another narrowband response. Under thesecircumstances the procedure is repeated with the increase and decrease of the frequency of the unwanted signal adjustedtwo and a half times the bandwidth previously referred to. If the degradation in performance remains unacceptable(subclause 6.2), the phenomena is considered wideband and therefore an EMC problem and the equipment fails the test.Each type of equipment shall fulfil the requirements of the present document on all frequency channels over which it isintended to operate.5Performance assessment5.1GeneralIf the ROMES has several optional features or configurations, tests shall be performed on the minimum representativeconfiguration of the EUT.In all cases, the minimum configuration of the EUT as marketed, shall comply with the EMC requirements of the presentdocument.The manufacturer shall keep on record information about the ancillary equipment intended for use with the ROMES andmake this information available to the user.The manufacturer shall keep on record the following information:-the ancillary equipment to be combined with the ROMES;-the user control functions and stored data that are required for normal operation and the method to be used toassess whether these have been lost after EMC stress;-an exhaustive list of ports, classified as either AC power, DC power or signal/control including the maximumallowed length of cable connected thereto;-the bandwidth of the IF-filter immediately preceding the demodulator;-the operating frequency bands over which the equipment is intended to operate;-the optional features of the equipment and the actual features of the equipment which are assessed for theperformance or degradation of performance.SIST EN 300 830:2000
