17、Electromagnetic compatibility and Radio spectrum Matters (ERM). The present document has been produced by ETSI in response to a mandate from the European Commission issued under Council Directive 98/34/EC (as amended) laying down a procedure for the provision of information in the field of technical

18、 standards and regulations. The present document 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 electromagnet

19、ic compatibility (“the EMC Directive“) (89/336/EEC 3 as amended) and Directive 1999/5/EC of the European Parliament and of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity (“the R ElectroMagnetic Compatibility (EM

20、C) standard for radio equipment and services; Part 1 : Common technical requirements“. Directive 1999/5/EC of the European Parliament and of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity (R a specific Quality o

21、f Transmission Measurement Apparatus (QTMA). b) 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 immunity tests of the EUT, a communications link shall be establi

22、shed between the EUT and the testing system. The EUT shall be placed in the operating mode. For EUT for which connection to a host equipment is necessary to offer functionality the manufacturer shall select which of the alternative performance assessment configurations shall be used.

24、odifications. For transmitters, the EUT shall be operated at its maximum rated RF output Peak Envelope Power (PEP), or at a level not less than -6 dB relative to that power level in the event of declared thermal limitations. The transmitter shall be modulated with a test signal which represents norm

25、al operation as specified by the manufacturer. A communication link shall be established at the start of the test and be maintained throughout the test.

27、g modifications. For the immunity tests of receivers, the wanted input signal, coupled to the receiver, shall be modulated with a test signal specified by the manufacturer which represents normal operation. For the measurement of the quality of transmission, a communications link shall be establishe

28、d 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. The Special

29、Test Equipment (STE), the QTMA and the source of the wanted input signal shall be located outside the test environment. 4.2.4 Arrangements for test signals at the output of receivers The provisions of EN 301 489-1 i, clause 4.2.4 shall apply with the following modifications. For the quality of trans

30、mission measurements the MES may be put in a specific mode of operation where the received data are looped back to the modulation input of the transmitter part of the EUT. 4.2.5 Arrangements for testing transmitter and receiver together (as a system) The provisions of EN 301 489-1 i, clause 4.2.5 sh

31、all apply. 4.3 Exclusion bands The provision of EN 301 489-1 i, clause 4.3 shall apply with the following modifications: - - the transmitter exclusion band and the receiver exclusion band as defined below shall apply, there shall be no exclusion bands for the ancillary equipment. 4.3.1 Transmitter e

32、xclusion band The transmitter exclusion band is the band of frequencies over which no tests of radiated immunity of a transmitter are made. The lower frequency of the transmitter exclusion band is the centre frequency minus twice the occupied bandwidth. The upper frequency of the transmitter exclusi

33、on band is the centre frequency plus twice the occupied bandwidth. 4.3.2 Receiver exclusion band The receiver exclusion band is the band of frequencies over which no tests of radiated immunity of a receiver are made. The lower frequency of the receiver exclusion band is the lower frequency of the co

34、mplete receive band of the EUT minus 5 % of that lower frequency. The upper frequency of the receiver exclusion band is the upper frequency of the complete receive band of the EUT plus 5 % of that upper frequency. 4.4 Narrow band responses of receivers The provisions of EN 301 489-1 i, clause 4.4 sh

35、all not apply. ETSI 10 ETSI EN 301 489-20 VI .2.1 (2002-1 1) 5 Performance assessment 5.1 Gen eral The provision of EN 301 489-1 i, clause 5.1 shall apply with the following modification. In addition, the manufacturer shall, at the time of submission of the equipment for test, declare comprehensivel

36、y the intended use of the equipment, and provide full and complete documentation necessary for user operation, testing and evaluation purposes. The present documentation shall include, but need not be limited to: - the ranges of the operational parameters, e.g. the power delivered to the antenna, th

37、e frequency ranges, the operational frequencies; the ancillary equipment andor host equipment to be combined with the MES for testing, if applicable; the user-control functions that are required for normal operation; the method and criteria to be used to assess the quality of transmission. - - - Thi

38、s information shall be in accordance with the documentation and the information leaflet accompanying the equipment and shall be recorded in the test report. 5.2 MES connected to host equipment For MES parts for which connection to or integration with a host equipment is necessary in order to offer a

39、dditional functionality, two alternative approaches are permitted. The manufacturer shall declare which alternative shall be used. 5.2.1 Alternative A: combined equipment A combination of a MES and a specific type of host equipment is used for testing according to the present document. Where more th

40、an one such combination is intended, testing shall not be repeated for combinations of MES and other host equipment where the latter are substantially similar, in particular such that host models are unlikely to significantly influence the intrinsic immunity and unwanted emissions of the MES. Where

41、more than one such combination is intended and host equipment are not substantially similar, one combination shall be tested against all requirements of the present document; all other combinations shall be tested separately for emissions only. 5.2.2 Alternative B: use of a test jig Where the MES is

42、 intended for use with a variety of host equipment, the manufacturer shall supply a suitable test jig that is representative of the range of host equipment in which the device is intended to be used. The test jig shall allow the MES part to be powered and stimulated in a way similar to the way it wo

43、uld be powered and stimulated when connected to or inserted into the host equipment. Measurements shall be made to all requirements of the present document. The test jig shall be designed such that alteration of the MESS intrinsic immunity and unwanted emissions is minimized. 5.3 Anci Ilary equ i pm

46、ll meet the requirements for base station e quip men t. - - A V-MES is an Installable Equipment (IE); a P-MES is a Portable Equipment (PE). 6 Performance criteria 6.1 Gen eral The equipment shall meet the minimum performance criteria as specified in clauses 6.2 and 6.3 The establishment of a communi

47、cations link at the start of the test, the maintenance of the communications link and the assessment of the recovered signal information is used as the performance criteria to ensure that the essential functions of the EUT are evaluated during and after the test. 6.2 Performance criteria for Continu

48、ous Phenomena (CP) The following procedures shall apply: during each individual exposure in the test sequence it shall be verified by the QTMA supplied by the manufacturer that the communications link is maintained, and that the quality of transmission observed is no worse than that declared by the

49、manufacturer; at the conclusion of the test: - the EUT shall operate as intended with no loss of user control functions or stored data, as declared by the manufacturer; - - under no circumstances shall the transmitter operate unintentionally. the communications link has been maintained during the test; and the quality of transmission observed is no worse than that declared by the manufacturer; ETSI 12 ETSI EN 301 489-20 VI .2.1 (2002-1 1) Reference to clauses in EN 301 489-1 I 9.7.3 Performance criteria; Voltaae dim and interruDtions 6.3 Special product-r
