Foreword This Candidate Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). The present document has been produced by ETSI in response to a mandate from the European Co

18、mmission issued under Council Directive 98/34/EC 4 (as amended) laying down a procedure for the provision of information in the field of technical standards and regulations. The present document together with EN 301 489-1 1 is intended to become a Harmonized Standard, the reference of which will be

26、the test conditions of EN 301 489-1 1, clause 4 shall apply as appropriate. 4.1 General For emission and immunity tests the test modulation, test arrangements, etc., as specified in the present document, clauses 4.1 to 4.4 shall apply. For the purpose of EMC tests, body worn or hand held transmitter

27、s shall be mounted on a non-conductive stand at least 0,8 m from any conducting surface. The EUT and any other equipment required for the performance assessment before, during, and after the conclusion of the tests, shall be connected in a manner typical of normal intended use. Whenever the EUT is p

28、rovided with a detachable antenna, it shall be tested with the antenna fitted in a manner typical of normal intended use. For immunity tests, if the equipment is of a category which permits it, a communications link shall be established at the start of the test and maintained during the test. The te

29、st conditions shall be as follows: the transmitter shall be operated at its normal maximum RF output power modulated with a suitable modulation signal (see clause 4.2.1); ETSI ETSI EN 301 489-28 V1.1.1 (2004-09) 7 for stand alone receivers or receivers of transceivers operating in simplex mode, the

30、wanted RF input signal, coupled to the receiver, shall be modulated with a suitable modulation signal (see clause 4.2.3); for duplex transceivers, the wanted RF input signal, coupled to the receiver, shall be modulated with a suitable modulation signal (see clause 4.2.3). The transmitter shall be op

31、erated at its normal maximum output power, modulated with the test modulation signal, coupled to the transmitter from the output of the receiver (repeater mode). 4.2 Arrangements for test signals The provisions of EN 301 489-1 1, clause 4.2 shall apply. 4.2.1 Arrangements for test signals at the inp

32、ut of transmitters The provisions of EN 301 489-1 1, clause 4.2.1 shall apply with the following modifications. For the purpose of the present document, the transmitter video or combined video/audio input signal shall be supplied by a generator at the correct impedance applied at the connections of

33、the stated inputs, unless otherwise stated (see figures 1 and 2). The manufacturer shall specify a representative test signal. 4.2.2 Arrangements for test signals at the output of transmitters The provisions of EN 301 489-1 1, clause 4.2.2 shall apply. 4.2.3 Arrangements for test signals at the inpu

34、t of receivers The provisions of EN 301 489-1 1, clause 4.2.3 shall apply with the following modifications. For the purpose of the present document, the transmitter video or combined video/audio input signal shall be supplied by a generator at the correct impedance applied at the connections of the

39、tended as follows: the lower frequency of the exclusion band is the lower frequency of the switching range, minus 5 % of the centre frequency of the switching range; the upper frequency of the exclusion band is the upper frequency of the switching range, plus 5 % of the centre frequency of the switc

40、hing range. 4.3.2 Transmitter exclusion band Exclusion bands shall not be applied when measuring transmitters in standby mode. For the purpose of the present document, the exclusion band shall extend over the frequencies above and below the fundamental transmitting frequency, but separated from the

41、centre frequency of the emission by 250 % of the relevant Channel Separation (CHS) of the radio-frequency channel arrangement where the system is to be placed. When the CHS is not defined the exclusion band shall extend over the frequencies above and below the fundamental transmitting frequency but

42、separated from the centre frequency of the emission by 250 % of the necessary bandwidth. ETSI ETSI EN 301 489-28 V1.1.1 (2004-09) 9 4.4 Narrow band responses of receivers The provision of EN 301 489-1 1, clause 4.4 shall apply. The nominal frequency offset used for the identification of narrowband r

43、esponses shall be twice the bandwidth of the receiver IF filter immediately preceding the demodulator, as declared by the manufacturer, for the first part of the identification procedure, and two and one half times the bandwidth of the receiver for its second part. The narrowband response shall be l

44、imited to less than 3 times the declared channel bandwidth (B) of the system. See EN 302 064-1 5. 5 Performance assessment 5.1 General The provision of EN 301 489-1 1, clause 5.1 shall apply with the following modification. In addition, the manufacturer shall at the time of submission of the equipme

45、nt for test, supply the following information to be recorded in the test report: the coupling means to be used for the application of the modulation signal to the EUT and for monitoring the output of the EUT; and the level and make up of the RF test signal for the establishment of the communications

46、 link; description of test fixtures. 5.2 Equipment which can provide a continuous communications link The provision of EN 301 489-1 1, clause 5.2 shall apply. 5.3 Equipment which does not provide a continuous communications link The provision of EN 301 489-1 1, clause 5.3 shall apply. 5.4 Ancillary

48、a specified in this clause and clauses 6.2, 6.3, 6.4, 6.5 and 6.6 as appropriate. The establishment and maintenance of a communications link and the assessment of loss of noise margin at the Quasi-Error-Free (QEF) point are used as performance criteria to ensure that all primary functions of the tra

49、nsmitter and receiver are evaluated during the immunity tests. In addition, the test shall also be performed in idle mode to ensure the transmitter does not unintentionally operate. The maintenance of a communications link shall be assessed using an indicator which may be part of the test system or the EUT. If an equipment is of a specialized nature, such that the performance criteria described in the following clauses are not appropriate, then the manufacturer shall declare, for inclusion in the test report, his own sp
