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.
