32、s of EN 301 489-1 1, clause 4 shall apply as appropriate. Further product related test conditions for VHF aeronautical radio equipment are specified in the present document. 4.1 General For emission and immunity tests the test modulation, test arrangements, etc., as specified in the present document

33、, clauses 4.2 to 4.5, shall apply. 4.2 Arrangements for test signals The provisions of EN 301 489-1 1, clause 4.2 shall apply with the following modification.

34、.1 Arrangement for test signals at the input to the transmitter The provisions of EN 301 489-1 1, clause 4.2.1 shall apply with the following modification. The transmitter shall be modulated with normal test modulation by an internal or external signal source capable of producing the appropriate dri

35、ve signal (see clause 4.5). 4.2.2 Arrangements for test signals at the output from the transmitter The provisions of EN 301 489-1 1, clause 4.2.2 shall apply with the following modifications. The transmitter shall be operated at its maximum rated RF output (PEP), or at a level not less than -6 dB re

36、lative to that power level in the event of declared thermal limitations. The RF output signal of the transmitter shall be coupled to the measuring equipment via a shielded transmission line such as a coaxial cable. The measuring equipment shall comprise a combination of a modulation analyser and an

37、audio distortion meter. For transmitters with an integral antenna, a 50 RF connection point shall be provided for test purposes. 4.2.3 Arrangements for test signals at the input to the receiver The provisions of EN 301 489-1 1, clause 4.2.3 shall apply with the following modifications. The wanted RF

38、 input signal coupled to the receiver shall be modulated with normal test modulation (see clause 4.5). For receivers with an integral antenna, a 50 RF connection point shall be provided for test purposes. 4.2.4 Arrangements for test signals at the output from the receiver The provisions of EN 301 48

39、9-1 1, clause 4.2.4 shall apply. 4.2.5 Arrangements for testing transmitters and receivers together (as a system) The provisions of EN 301 489-1 1, clause 4.2.5 shall apply.

40、89-1 1, clause 4.3 shall apply. Frequencies on which radio communications equipment is intended to operate are excluded from immunity tests with radiated RF test signals. The RF test exclusions are referred to as “exclusion bands“ and are detailed below for the various cases. 4.3.1 Transmitter exclu

41、sion bands for EM emission measurements Exclusion bands shall apply when measuring transmitters in transmit mode of operation. Exclusion bands shall not apply when measuring transmitters in standby mode of operation. The exclusion band for transmitters is given in table 1. Table 1: Transmitter exclu

42、sion bands for emission measurements Category of EUT (Channel spacing) Width of exclusion band (see notes 1 and 2) Centre of exclusion band 8,33 kHz equipment 2,042 MHz or 2,442 MHz Fc 25 kHz equipment 2,125 MHz or 2,525 MHz Fc NOTE 1: The exclusion band is the product of 5 times the receiver bandwi

43、dth plus 20 times the measurement bandwidth (i.e. 100 kHz, or 120 kHz), for the measurement range 30 MHz to 1 GHz. NOTE 2: The extension of the exclusion bandwidth for transmitters to include 20 times the measurement bandwidth is needed to accommodate the skirt bandwidth of the filters used in the m

44、easurement equipment. A narrower measurement bandwidth may be used. The exclusion band and measurement bandwidth shall be recorded in the test report. 4.3.2 Receiver exclusion bands for EM emission measurements There shall be no frequency exclusion band applied to EM emission measurements of receive

45、rs, or ancillaries. 4.3.3 Transmitter exclusion bands for immunity tests The exclusion band extends plus and minus twice the occupied bandwidth (BW) from the centre frequency (Fc 2BW). For 25 kHz equipment the exclusion band extends 50 kHz, and for 8,33 kHz equipment 16,7 kHz around the centre frequ

46、ency (Fc). 4.3.4 Receiver exclusion bands for immunity tests The exclusion band is the operating frequency range, extended at each end by 5 % of the centre frequency (Fc). EXAMPLE: For the centre frequency 127,5 MHz, the exclusion band extends from 111,625 MHz (i.e. 118 MHz minus 6,375 MHz) to 143,3

47、5 MHz (i.e. 136,975 MHz plus 6,375 MHz). 4.4 Narrow band responses of receivers Any receiver response to an RF immunity test that has a bandwidth as defined in EN 301 489-1 1, clause 4.4. shall be considered a narrow band response, and shall be subject to spurious response rejection tests specified

48、in the relevant product standards for the effective use of the radio spectrum. ETSI ETSI EN 301 489-22 V1.3.1 (2003-11) 9 4.5 Normal test modulation The normal test modulation is specified as follows: for analogue speech equipment: - the receiver input signal shall be set to the nominal operating fr

49、equency, modulated with a sinusoidal audio frequency of 1 kHz at 30 % depth and at a level which gives a SINAD ratio of 20 dB, measured at the receiver output using a psophometric telephone filtering network as described in ITU-T Recommendation P.53 6; - the transmitter shall be modulated with a sinusoidal audio frequency signal of 1 kHz. The level of this audio signal shall be set to obtain at least 80 % modulation depth of the RF output signal. for VDL Mode 2 and VDL Mode 4 equipment: - the receiver input signal shall be s
