10、174 MHz and 400 MHz; - 100 kHz between 400 MHz and 790 MHz; - 4 kHz between 790 MHz and 862 MHz; - 100 kHz between 862 MHz and 1 000 MHz; - 100 kHz above 1 000 MHz.

11、6-1-1 3 or CISPR 16-2-3 4. 4.1.2 Test modulating signal The modulation signal at the input of the transmitter shall be according to OFDM signal defined in the equipment technical specification with the following specific settings: The FFT mode supported by the EUT. If more than one mode are supporte
12、d by the EUT, the mode with the largest FFT size. The guard interval duration supported by the EUT. If more than one guard interval duration are supported by the EUT, the guard interval with the shortest duration. The modulation constellation supported by the EUT. If more than one modulation constel
13、lation are supported by the EUT, the constellation with the highest order. The code ratio supported by the EUT. If more than one code ratio are supported by the EUT, an optional code ratio declared by the equipment manufacturer (or the code with the lowest ratio). 4.2 Test arrangement for measuremen
14、t of spurious emissions See clause 5.3.1 in 2 for initial conditions, test procedure and test requirements. 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 shou
15、ld be known. NOTE 2: For high power transmitters the preferred set up would require 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 incl
16、ude any output filter, an external filter shall be added after the transmitter for 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 measurem
17、ents shall be performed at the output of this extra filter.

NOTE 1: Disconnect the power amplifier from the output filter. NOTE 2: The frequency response of the outp

NOTE 4: The out-of-band spectrum of the OFDM signal shall be calculated by applying the recorded frequency response o
20、f the output filter to the recorded spectrum of the OFDM signal. NOTE 5: If the transmitter does not include any output filter, an external filter shall be added after the transmitter for the testing arrangement. This filter shall be representative of the multiplexer or filter existing in operationa
21、l 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.

25、st specifications Table (HS-RTT) The HS Requirements 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) sp
26、ecific clause(s) in (a) specific referenced document(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
27、requirement to be either: - Unconditional: meaning 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,
28、it associates the requirement with the particular optional service or functionality; it qualifies each test procedure to be either: - Essential: meaning that it is included with the Essential Radio Test Suite and therefore the requirement shall be demonstrated to be met in accordance with the refere
29、nced procedures; - Other: meaning that the test procedure is illustrative but other means of demonstrating compliance with the requirement are permitted. Table A.1: HS Requirements and conformance Test specifications Table (HS-RTT) Harmonized Standard EN 302 998-2 The following requirements and test
30、 specifications are relevant to the presumption of conformity under the article 3.2 of the R those designated “O“ make up the Other Test Suite; for those designated “X“ there is no test specified corresponding to the requirement. The completion of all tests classified “E“ as specified with satisfact
31、ory outcomes is a necessary condition for a presumption of conformity. Compliance with requirements associated with tests classified “O“ or “X“ is a necessary condition for presumption of conformity, although conformance with the requirement may be claimed by an equivalent test or by manufacturers a
32、ssertion supported by appropriate entries in the technical construction file. Clause Number Identification of clause(s) defining the test specification in the present document unless another document is referenced explicitly. Where no test is specified (that is, where the previous field is “X“) this
