Test frequencies: 1) the lowest operating frequency of the EUT; 2) the highest operating frequency of the EUT; 3) a frequency mid-way between 1) and 2) above. Test arrangement (see Figure 5.1): 1) connect the EUT to th

25、e test load, via the coupling device; ETSI ETSI EN 302 296-2 V1.2.1 (2011-05) 182) connect the spectrum analyser to the coupling device. For the purposes of this test no test signal is required, the manufacturer shall ensure that the full rated output power of the transmitter will be maintained duri

27、5.4.1.4 Test arrangement NOTE 1: The optional filter should suppress the output signal so that no intermodulation products are generated by the spectrum analyser. The insertion loss throughout the measuring range should be known. NOTE 2: For high power transmitters the preferred set up would require

28、 A to be connected to B and A1 to be connected to B1. NOTE 3: For low power transmitters the preferred set up would require A to be connected to C and A1 to be connected to C1. NOTE 4: If the transmitter does not include any output filter, an external filter shall be added after the transmitter for

29、the testing arrangement. This filter shall be representative of the multiplexer or filter existing in operational conditions and viewed by the transmitted output when installed. In this case, the antenna port measurements shall be performed at the output of this extra filter. Figure 5.1: Testing arr

44、s and conformance Test specifications Table (HS-RTT) in Table A.1 serves a number of purposes, as follows: it provides a statement of all the requirements in words and by cross reference to (a) specific clause(s) in the present document or to (a) specific clause(s) in (a) specific referenced documen

45、t(s); it provides a statement of all the test procedures corresponding to those requirements by cross reference to (a) specific clause(s) in the present document or to (a) specific clause(s) in (a) specific referenced document(s); it qualifies each requirement to be either: - Unconditional: meaning

46、that the requirement applies in all circumstances; or - Conditional: meaning that the requirement is dependent on the manufacturer having chosen to support optional functionality defined within the schedule. in the case of Conditional requirements, it associates the requirement with the particular o

48、cedure is illustrative but other means of demonstrating compliance with the requirement are permitted.
