(e.g. muting, clicks, warbles or squeaks).
4.2.4.3 Conformance
Conformance tests as defined in clause 5.3.4 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.

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.

4.2.4 Adjacent channel selectivity and blocking
4.2.4.0 Definition
The selectivity of a receiver is a measure of its ability to discriminate between a wanted signal to which the receiver is
tuned and unwanted signals entering the broadcast receiver tuning port.
4.2.4.1 General requirements
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
signals at a greater separation from the wanted signal, known as blocking or far-off selectivity. The channel spacing
specified in table 3 shall apply.

4.2.4.3 Conformance
Conformance tests as defined in clause 5.3.1 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 Unwanted emissions in the spurious domain
4.2.5.1 Definition
Unwanted emissions in the spurious domain are emissions from the equipment in the frequency range defined by
CEPT/ERC/Recommendation 74-01E [i.7].
4.2.5.2 Limits
The limits in CENELEC EN 55032 [4], Class B shall not be exceeded.
4.2.5.3 Conformance
Manufacturers shall provide a representative sample of the receiver system. The level of spurious emissions shall be
measured by either:
a) conducted (conducted differential voltage) emissions from an external RF port; and radiated emissions from
the cabinet and structure of the equipment (cabinet radiation); or
b) radiated emissions from the cabinet and the integral antenna.
Conformance tests as defined in clause 5.3.2 shall be carried out.
4.2.6 Sensitivity
4.2.6.1 Definition
Receiver sensitivity is the ability to receive a wanted signal at low input signal levels while providing a pre-determined
level of performance.
Receiver sensitivity is only specified for digital systems. The AM and FM bands are characterized by wide variations in
the level of co-channel interference and therefore specifying a minimum requirement for sensitivity creates a limitation
to the solutions provided by manufacturers. DAB and DRM have been designed to cope with variable levels of
interference and system performance is determined by ensuring sufficient sensitivity.

NOTE 1: The requirements in table 5 are defined for the receiver including casing. Hence modules need better values to
compensate for losses of the casing.
NOTE 2: It has to be taken into account that the sensitivity of the receiver measured with a cable to the broadcast receiver
tuning port should be better than stated in table 5 to compensate for additional receiver internal interferences when
measuring the sensitivity with built-in antenna.
When stating the sensitivity performance of a receiver with built-in antenna, a precise description of the measurement
set-up including TEM-cell type, size and calibration method has to be given.
4.2.6.3 Conformance
Conformance tests as defined in clause 5.3.3 shall be carried out. Only demodulation systems supported by the receiver
shall be tested. Only bands supported by the receiver shall be tested.
5 Testing for compliance with technical requirements
5.1 Environmental conditions for testing
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.

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.
