4.2.4.3 Conformance Conformance tests as defined in clause 5.3 shall be carried out. Only demodulation systems supported by the receiver shall be tested. Only bands supported by the receiver shall be tested. 4.2.5 Adjacent channel selectivity and blocking 4.2.5.1 Definition The adjacent channel selectivity at a given frequency separation, is the ratio of the maximum unwanted signal level to the wanted signal level necessary to provide a given level of audio quality. The wanted and unwanted signals are of the same modulation type. The blocking ratio at a given frequency separation, is the ratio of the maximum AM unwanted signal level to the wanted signal level necessary to provide a given level of audio quality. The appropriate measure of audio quality, known as the impairment criteria, are specified for each modulation type. In order to provide effective use of spectrum, devices shall be able to demodulate the tuned signal in the presence of similar signals in adjacent channels. The first, second and third adjacent channels both above and below the tuned signal shall be tested. In addition, testing shall also be performed to check the ability of the receiver to work effectively with interfering signals at a greater separation from the wanted signal (blocking). The channel spacings specified in table 7 shall apply. oSIST prEN 303 345 V1.1.1:2016
