29、d (1 18 MHz to 136,975 MHz), using Double Sideband Amplitude Modulation with 8,33 kHz or 25 kHz channel spacing. The present document may be used by accredited test laboratories for the assessment of the performance of the equipment. The performance of the equipment submitted for type testing should

30、 be representative for the performance of the corresponding production model. The present document has been written on the assumption that: - the type test measurements will be performed only once, in an accredited test laboratory and the measurements accepted by the various authorities in order to

31、grant type approval; if equipment available on the market is required to be checked it will be tested in accordance with the methods of measurement specified in the present document. - ETSI 8 ETSI EN 300 676 VI .3.1 (2003-03) 1 Scope The present document states the minimum performance requirements f
