9、ssessment of radiocommunication and ancillary equipment in respect of Elecmomagnetic Compatibility (EMC). Technical specifications related to the antenna port are found in the related product standard ETS 300 441 191 for the effective use of the radio specttum. The present document specifies the app

10、licable EMC tests, the test methods, the limits and the minimum performance criteria for maritime radiotelephone watch receivers operating on 2 182 kHz and the associated ancillary equipment. The electromagnetic environment used in the present document to develop the technical specifications encompa

11、sses the electromagnetic environment on board ships as identified in EN 60945 101. The EMC requirements have been selected to ensure an adequate level of Compatibility for apparatus in maritime environments. The levels do not cover extreme cases which may occur in any location but have a low probabi

12、lity of occurrence. Compliance of radio equipment to the requirements of the present document does not signify compliance to any requirements related to the use of the equipment. Compliance to the present document does not signify compliance to any safety requirements. However, it is the responsibil

13、ity of the assessor of the equipment that any observations regarding apparatus becoming dangerous or unsafe as a result of the application of the tests defined in the present document, should be recorded in the test report. 2 Normative references References may be made to: specific versions of publi

23、ver, transmitter or transceiver is considered as an ancillary equipment (apparatus) if: - the equipment is intended for use in conjunction with a receiver, transmitter or transceiver to provide additional operational and/or control features to the radio equipment (e.g. to extend control to another p

24、osition or location); and the equipment cannot be used on a stand alone basis to provide user functions independently of a receiver, transmitter or transceiver; and - - the receiver, transmitter or transceiver to which it is connected, is capable of providing some intended operation such as transmit

25、ting and/or receiving without the ancillary equipment, Le. it is not a sub-unit of the main equipment essential to the main equipment basic functions. artificial antenna: A non-radiating load of 10 Sl in series with 250 pF. signal relative humidity: 20 % to 75 %. The normal test voltage for equipmen

26、t to be connected to the AC mains, shall be the nominal mains voltage. The frequency of the test voltage shali be 50 Hz k 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,

27、the normal test voltage shall be declared by the manufacturer. The test configuration shall be as close as possible to normal intended use. If the equipment is part of a system, or can be connected to ancillary equipment, then it shall be acceptable to test the equipment while connected to the minim

28、um representative configuration of ancillary equipment necessary to exercise the ports. Ports which in normal operation are connected shall be connected to an anciliary equipment or to a representative piece of cable correctly terminated to simulate the inpuuoutput characteristics of the anciliary e

29、quipment. RF input ports shall be correctly terminated. If the equipment has a large number of ports, then a sufficient number shall be selected to simulate actual operation conditions and to ensure that aii the different types of termination are tested. Ports which are not connected to cables durin

30、g normal intended operation, e.g. service connectors, programming connectors, temporary connectors etc. shall not be connected to any cables for the purpose of Eh4C testing. Where cables have to be connected to these ports, or interconnecting cables have to be extended in length in order to exercise

31、 the EUT, precautions shall be taken to ensure that the evaluation of the EUT is not affected by the addition or extension of these cables. The test conditions, test configuration and mode of operation shall be recorded in the test report. 4.1.1 Emission tests This subclause defrnes the test conditi

32、ons 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 being investigated consistent with normal applications; an attempt shall be made to maximize the detected radiated emissions for exampl

33、e by moving the cables of the equipment. - ETSI STD-ETSI EN 3UL 090-ENGL 1998 3LI00855 033qOOO 91T 9 EN 301 O90 V1.l.l (1 998-09) 4.1.2 Immunity tests This subclause defines the test conditions and configurations for the immunity tests as follows: - - the measurement shall be made in the mode of ope

34、ration as required in subclause 4.1.2.1; for the immunity tests of ancillary equipment without separate pass/fail criteria, the receiver, transmitter or transceiver coupled to the ancillary equipment, shall be used to judge whether the ancillary equipment passes or fails. 4.1.2.1 Mode of operation F

35、or the immunity tests, the wanted input signal, coupled to the receiver, shall be the normal test signal a) (subclause 4.1.2.2) except where otherwise stated. For immunity tests requiring performance criterion A, the EUT shall be put in the non-muted state before the test. For immunity tests requiri

36、ng performance criteria B or C, the EUT shall be put in the muted state before the test. 4.1.2.2 Normal test signal The following normal test signals are defined: a) an A2A signal on the frequency of 2 182 kHz with a level of 60 dBFV (emf) modulated with 1 kHz to a depth of 30 %; b) an A2A signal on

37、 the frequency of 2 182 kHz with a level of 60 dBpV (emf) modulated with the radiotelephone alarm signal (see ETS 300 44 1 191) to a depth of 70 %. 4.1.2.3 Arrangements for test signals at the input of the receiver Test signal sources shall be connected to the receiver input in such a way that the i

38、mpedance presented to the receiver input is 50 R. Adequate measures shall be taken to avoid the effect of the unwanted signal on the measuring equipment 4.1.2.4 Receiver exclusion band The exclusion band is the frequency range 2 065 kHz to 2 300 kHz. 4.1.2.5 Narrow band responses Responses occurring

39、 during the test at discrete frequencies which are narrow band responses (spurious responses) are identified by the method specified in this subclause. If an unwanted signai causes an SND/N of less than 10 dB it is necessary to establish whether the distortion is due to a narrowband response or to w

40、ideband phenomena. Taking the initial test frequency as reference the procedure is repeated with an increase of the unwanted signal frequency by 40 kiiz. If the SND/N recovers to not less than 10 dB, then the response is considered as a narrowband response. If the SND/N is still less than 10 dB, the

41、 test is repeated with the frequency of the unwanted signal decreased by 40 kHz. If the SND/N recovers to not less than 10 dB, the response is considered as a narrowband response. If the SND/N is still less than 10 dB, this may be due to the fact that the offset has made the frequency of the unwante

42、d signal correspond to the frequency of another narrowband response. Therefore, taking the initial test frequency as reference the procedure is repeated with an increase of the unwanted signal frequency by 50 kHz.

43、9) If the SND/N recovers to not less than 10 dB the response is considered as a nmwband response. If the SNDIN is still less than 10 dB, the test is repeated with the frequency of the unwanted signal decreased by 50 kHz. If the SND/N is still less than 10 dB, the phenomenon is considered wideband an

44、d therefore an EMC problem and the equipment fails the test All narrowband responses shall be disregarded. 5 Performance assessment 5.1 General The manufacturer shall, supply the following information to be recorded in the test report: - - the ancillary equipment to be combined with the radio equipm

45、ent for testing (where applicable); an exhaustive list of ports, with the maximum cable lengths allowed, classified as either power, signal or control. Power ports shall further be classified as AC or DC power. 5.2 Ancillary equipment At the manufacturers discretion an ancillary equipment may be: -

46、declared compliant separately from the receiver to all the applicable immunity and emission clauses of the present document; - - declared compliant to another appropriate harmonized EMC standard; tested with it connected to the receiver in which case compliance shall be demonstrated to the appropria

47、te clauses of the present document. 6 Performance criteria 6.1 General The equipment shall meet the minimum performance criteria as specified in subclauses 6.2,6.3, 6.4, for the tests indicated in table2 (clause 7). 6.2 Performance criteria A for continuous phenomena The EUT shall continue to operat
