For the purposes of the present document, the terms given in Directive 2014/53/EU [i.1] and the following apply:

adjacent channel selectivity: at a given frequency separation, ratio of the maximum unwanted signal level to the

blocking: at a given frequency separation, ratio of the maximum AM unwanted signal level to the wanted signal level

external antenna: antenna designed to be connected to the equipment with the use of a 50 Ω or 75 Ω external

integral antenna: antenna which is detachable from the equipment without the use of any tools, and not using a 50 Ω

NOTE: A device that uses a supplied earphone as the antenna has an integral antenna.

sensitivity: minimum wanted signal level required to provide a given level of audio quality

The following broadcast radio modulation methods are considered feasible within the current authorization regime in

Broadcast radio receivers may include demodulation capability for one or more of these modulation methods.

Conformance shall only be required for each of the modulation methods included in the receiver.

The following frequency bands are identified in the ECA table [i.4] for broadcast radio services:

• High Frequency (HF): 3 950 kHz to 4 000 kHz, 5 900 kHz to 6 200 kHz, 7 200 kHz to 7 450 kHz, 9 400 kHz

to 9 900 kHz, 11 600 kHz to 12 100 kHz, 13 570 kHz to 13 870 kHz, 15 100 kHz to 15 800 kHz, 17 480 kHz

to 17 900 kHz, 18 900 kHz to 19 020 kHz, 21 450 kHz to 21 850 kHz and 25 670 kHz to 26 100 kHz.

Broadcast radio receivers may include tuning capability for one or more of these frequency bands. Conformance shall

The equipment shall be tested under normal test conditions according to the relevant product and basic standards or to

the information accompanying the equipment, which are within the manufacturers declared range of humidity,

temperature and supply voltage. The test conditions shall be recorded in the test report.

The interpretation of the results recorded in a test report for the measurements described in the present document shall

• the measured value related to the corresponding limit will be used to decide whether an equipment meets the

• the value of the measurement uncertainty for the measurement of each parameter shall be included in the test

• the recorded value of the measurement uncertainty shall be, for each measurement, equal to or less than the

For the test methods, according to the present document, the measurement uncertainty figures shall be calculated and

shall correspond to an expansion factor (coverage factor) k = 1,96 or k = 2 (which provide confidence levels of

respectively 95 % and 95,45 % in the case where the distributions characterizing the actual measurement uncertainties

are normal (Gaussian)). Principles for the calculation of measurement uncertainty are contained in ETSI

Two generic methods of measurement are applicable to verifying the performance of the receiving equipment in

question. The conducted test methods shall be used for receivers with an external antenna connector. The radiated test

For both generic methods, two generators are needed. One provides the wanted signal, and the other the unwanted

signal, or interferer (when required). The two signals are combined in such a way as to maintain isolation between the
