    4、 ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). The present document has been produced by ETSI in response to a mandate from the European Commission issued under Council Directive 98/34/EC i.1 (as amended) laying down a procedure for the provision of informa

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

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

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

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

    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.
