For non-specific references, the latest version of the referenced document (including any amendments) applies. i.1 Directive 1999/5/EC of the European Parliament and of the Council of 9 M
27、arch 1999 on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity (R b) the specific Quality of Transmission Measurement Apparatus (QTMA). For the measurement of the quality of transmission a communications link shall be established and the wanted
28、input signal shall be applied to the Radio Frequency (RF) input of the receiver via the antenna. The special test equipment, the QTMA and the source of the wanted input signal shall be located outside the test environment. Adequate measures shall be taken to protect them from the effects of all the
29、radiated fields within the test environment. 4.2.1 Arrangements for test signals at the input of transmitters The provisions of EN 301 489-1 1, clause 4.2.1 shall apply. 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.

For tests on the receiver, the level of the signal received from the test transmitter shall be as close as
31、possible to the normal operation level of the EUT receiver. 4.2.4 Arrangements for test signals at the output of receivers The provisions of EN 301 489-1 1, clause 4.2.4 shall apply. 4.2.5 Arrangements for testing transmitter and receiver together (as a system) The provisions of EN 301 489-1 1, clau
32、se 4.2.5 shall apply. 4.3 Exclusion bands There are no exclusion bands for ESs within in the scope of the present document. 4.4 Narrow band responses of receivers Narrow band responses are not allowed for ESs within in the scope of the present document. 5 Performance assessment 5.1 General The provi
33、sion of EN 301 489-1 1, clause 5.1 shall apply. In addition the manufacturer shall provide the following information to be recorded in the test report: - the dedicated grade (A or B) for the ES in accordance with the information contained in the instructions accompanying the ES (see clause 5.3); - t
34、he ranges of the operational parameters, e.g. the power delivered to the antenna, the frequency ranges; - the minimum quality of transmission, and the method to be used to assess it. This information shall be in accordance with the documentation accompanying the equipment. 5.2 Equipment configuratio
35、n(s) For radiation measurements in carrier-on state, the ES shall be put in a continuous transmit mode or to the maximum burst rate where applicable. The ES shall be operated at the highest normal operating Equivalent Isotropically Radiated Power (EIRP) or, if that is the maximum attainable, then 3
36、dB below such maximum. A suggested test configuration is shown in figure 1. ETSI ETSI EN 301 489-12 V2.2.2 (2008-09) 10Figure 1: Suggested test configuration For the tests, the ES antenna reflector and the test antenna may be removed at their flanges and be replaced by one direct wave guide connecti
37、on. The following test equipment shall be the means whereby the correct operation of the EUT is verified: a) the power meter measures the output power and is used to confirm the transmission disabled, carrier-on and carrier-off states and output level consistency; b) the frequency counter measures t
38、he centre frequency of the radiated carrier in the absence of modulation; c) the spectrum analyser measures the bandwidth of the transmission; d) the test receiver is used to demodulate the transmitted signal; e) the two QTMA are used in conjunction with each other to assess the quality of transmiss
39、ion; f) the test transmitter is used to control the switching between transmission disabled, carrier-on and carrier-off states by transmitting the control and monitoring signals. 5.3 Equipment classification The provisions of EN 301 489-1 1, clause 5.5 set out for base stations shall apply with the
40、following addition. The equipment are classified into the two grades of service: - grade A of ES for which short interruptions of transmission are accepted during immunity testing with EMC transient phenomena; - grade B of ES for which no short interruption of transmission is accepted during immunit
41、y testing with EMC transient phenomena. The applicable grade A or B shall be declared by the manufacturer, it shall be in accordance with the information contained in the instructions accompanying the ES, and shall be recorded in the test report. ETSI ETSI EN 301 489-12 V2.2.2 (2008-09) 116 Performa
42、nce criteria The definition of the functions of the EUT, including its ancillary equipment, to be checked during and after the EMC tests shall be declared by the manufacturer and recorded in the test report. The equipment shall meet the minimum performance criteria as specified in clauses 6.1, 6.2 a
43、nd 6.3 and additionally the functions as declared by the manufacturer. 6.1 Performance criteria (C) for Continuous phenomena applied to the EUT The provisions of EN 301 489-1 1, clause 6.1 shall apply with the following modification. The EUT shall be considered to satisfy the immunity if the followi
44、ng conditions are met during and after the exposure: a) the quality of transmission observed is no worse than that declared by the manufacturer (clause 5.1); b) the EUT is able to be placed in the transmission disabled state, and does not leave that state without being commanded; c) when the EUT is
45、in the transmission disabled state there is no change in the signal level; d) when the EUT is in the carrier-on state there is no change in the signal level or frequency; e) when the EUT is in the carrier-off state there is no increase of the signal level; f) for ESs capable of transmitting, under n
46、o circumstances does the transmitter operate unintentionally during the test; g) the EUT operates as intended with no loss of user control functions, stored data and the communications link. 6.2 Performance criteria (TA) for Transient phenomena applied to a grade A EUT The provisions of EN 301 489-1
47、 1, clause 6.2 shall apply with the following modification. The EUT shall be considered to satisfy the immunity specifications if the following conditions are met: - during and after the series of individual exposures: a) the EUT is able to be placed in the transmission disabled state, and does not
48、leave that state without being commanded; b) when the EUT is in the transmission disabled state there is no change in the signal level; c) when the EUT is in the carrier-on state there is no change in the signal frequency or increase of the signal level; d) when the EUT is in the carrier-off state t
49、here is no increase of the signal level; e) for ESs capable of transmitting, under no circumstances does the transmitter operate unintentionally during the test; - at the conclusion of each exposure the quality of transmission observed shall be no worse than that declared by the manufacturer (clause 5.1); - at the conclusion of the total test comprising the series of individual exposures the EUT shall operate as intended with no loss of user control functions or stored data and the communications link shall remain maintained.
