29、 EN 301 489-1 i, clause 4 shall apply as appropriate. Further provisions related to test conditions for broadcasting service transmitters are specified in the present document. 4.1 Gen eral For emission and immunity tests the test modulation, test arrangements, etc. as specified in the present docum
30、ent, clauses 4.1 to 4.5 shall apply. For immunity tests, the output of the Tx shall be monitored as specified in the present document, clause 4.2.3. 4.2 Arrangements for test signals The provisions of EN 301 489-1 i, clause 4.2 shall apply. 4.2.1 Arrangements for test signals at the input of transmi
31、tters The provisions of EN 301 489-1 i, clause 4.2.1 shall apply, with the following modifications: If the transmitter under test incorporates base-band processing andor coding equipment (e.g. a NICAM encoder for an analogue modulated TV transmitter, or an MPEG2 encoder for a digital television tran
32、smitter), then this equipment shall be active as in normal operation. The manufacturer shall provide reference encoders and the tests shall be carried out with these in operational mode. If the transmitter under test does not include integrated base-band processing andor coding equipment, the manufa
33、cturer shall declare whether the transmitter is designed for operation with or without encoder(s). The manufacturer shall clearly state this in the product documentation. If the transmitter under test is designed for operation with externally fitted encoder(s), then it is lefi to the decision of the
34、 manufacturer whether the transmitter under test shall be tested with such encoder(s). Depending on the manufacturers decision, the manufacturer may have to provide reference encoders and the tests shall be carried out with these in operational mode. Any unused input port of the transmitter under te
35、st shall be terminated according to the manufacturers instructions. 4.2.2 Arrangements for test signals at the input of transposers, active deflectors, or RF power amplifiers The provisions of EN 301 489-1 i, clause 4.2.1 shall apply, with the following modifications: In case of transposers and acti
36、ve deflectors, the wanted RF input signal, at a frequency determined from the manufacturers specification, shall be set to a level equal to the mid point of the range declared by the manufacturer. In case of RF amplifiers, the wanted RF input signal of a suitable level shall be delivered from an ade
37、quate external modulator provided by the manufacturer. The modulator may be placed outside the test environment. A broadcasting transmission shall be established at the start of the test and maintained during the test. ETSI 8 ETSI EN 301 489-14 V1.2.1 (2003-05) 4.2.3 Arrangements for test signals at
38、 the output of transmitters, transposers, active deflectors or RF power amplifiers The provisions of EN 301 489-1 i, clause 4.2.2 shall apply with the following modifications. Typical test arrangements to assess the performance of the EUT are shown in: NOTE: figure 1 for analogue modulated TV transm
39、itters; figure 2 for T-DVB transmitters. In practice it is not necessary to use all the individual instrumentation shown in figure 1.

42、.2 and 4.3.3 of the present document. 4.3.1 Transmitter and RF power amplifier exclusion band The exclusion band for the transmitter andor power amplifier shall be the allocated channel. 4.3.2 Active deflector exclusion band The exclusion band for the active deflector (transmitting and receiving ele
43、ments) is equal to the channel centre frequency -5 % to +5 %. Special precautions shall be taken to avoid the wanted RF output of the active deflector from disturbing the signal at the RF input port. 4.3.3 Transposer exclusion band For emission measurements, the transposer exclusion band shall compr
44、ise the exclusion band of the transmitting element of the equipment under test only. For immunity tests with continuous phenomena, the transposer exclusion bands shall comprise both the exclusion bands of the transmitting and receiving elements of the equipment under test. The exclusion band for the
45、 transposer (transmitting and receiving elements) is equal to the channel centre frequency for each element -5 % to +5 %. For the receiver part of the transposer, the exclusion band takes into account the blocking effect that may occur due to the high level of the immunity test fieldstrength (10 V/m
46、) in regard to the RF input level of that receiver part (which is usually less than 1 mV). ETSI 10 ETSI EN 301 489-14 VI .2.1 (2003-05) 4.4 Narrow band responses of receivers The provisions of EN 301 489-1 i, clause 4.4 shall apply during the immunity tests of transposers and active deflectors to co
47、ntinuous phenomena. 4.5 Normal test modulation 4.5.1 Analogue Modulation The vision carrier shall be amplitude modulated with composite sync pulses and a 350 mV luminance bar, the sound 1 (mono) carrier shall be frequency modulated with a 1 kHz sinusoidal signal at a level to cause a frequency devia
48、tion of 50 kHz and the sound 2 (NICAM) carrier shall be DQPSK modulated with a pseudo random bit sequence. 4.5.2 Digital Modulation (T-DVB) The modulation signal at the input of the transmitter shall be as stated in EN 300 744 6, clause 4.3, but with the following specific settings: Mode 8K; Guard i
49、nterval duration 1/32; TS modulation 64 QAM; Code Ratio 213. 5 Performance assessment 5.1 Gen eral The provisions of EN 301 489-1 i, clause 5.1 shall apply. In addition, the manufacturer shall, at the time of submission of the equipment for testing, declare the following information, also to be recorded in the test report, as appropriate : the frequencies as used in the transmitter for oscillators, clocks and intermediate frequencies; the bandwidth of the IF filter, or the bandwidth of the RF filter if no IF signal processing is used; for RF ampl
