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.
5.2 Interpretation of the measurement results
The interpretation of the results recorded in a test report for the measurements described in the present document shall
be as follows:
• the measured value related to the corresponding limit will be used to decide whether an equipment meets the
requirements of the present document;
• the value of the measurement uncertainty for the measurement of each parameter shall be included in the test
report;
• the recorded value of the measurement uncertainty shall be, for each measurement, equal to or less than the
figures in table 1.
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
TR 100 028 [i.2], in particular in annex D of the ETSI TR 100 028-2 [i.3].
Table 1 is based on such expansion factors.
Table 1: Maximum measurement uncertainty
Parameter Uncertainty
Uncertainty in conducted measurements ±1 dB
Uncertainty in radiated measurements ±6 dB
5.3 Methods of measurement
5.3.1 Generic methods of measurement
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
methods shall be used for all other receivers.
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
generators. It is necessary to provide calibrated attenuators for control of the individual levels; very often these will be
built into the generators. Where the attenuators are external, cable lengths should be kept short to avoid cross-coupling
effects.
The tests require the audio output of the receiver to be measured. All tonal controls (user operated and/or preset,

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.
5.2 Interpretation of the measurement results
The interpretation of the results recorded in a test report for the measurements described in the present document shall
be as follows:
• the measured value related to the corresponding limit will be used to decide whether an equipment meets the
requirements of the present document;
• the value of the measurement uncertainty for the measurement of each parameter shall be included in the test
report;
• the recorded value of the measurement uncertainty shall be, for each measurement, equal to or less than the
figures in table 1.
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
TR 100 028 [i.2], in particular in annex D of the ETSI TR 100 028-2 [i.3].
Table 1 is based on such expansion factors.
Table 1: Maximum measurement uncertainty
Parameter Uncertainty
Uncertainty in conducted measurements ±1 dB
Uncertainty in radiated measurements ±6 dB
5.3 Methods of measurement
5.3.1 Generic methods of measurement
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
methods shall be used for all other receivers.
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
generators. It is necessary to provide calibrated attenuators for control of the individual levels; very often these will be
built into the generators. Where the attenuators are external, cable lengths should be kept short to avoid cross-coupling
effects.
The tests require the audio output of the receiver to be measured. All ton

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.
5.2 Interpretation of the measurement results
The interpretation of the results recorded in a test report for the measurements described in the present document shall
be as follows:
• the measured value related to the corresponding limit will be used to decide whether an equipment meets the
requirements of the present document;
• the value of the measurement uncertainty for the measurement of each parameter shall be included in the test
report;
• the recorded value of the measurement uncertainty shall be, for each measurement, equal to or less than the
figures in table 1.
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
TR 100 028 [i.2], in particular in annex D of the ETSI TR 100 028-2 [i.3].
Table 1 is based on such expansion factors.
Table 1: Maximum measurement uncertainty
Parameter Uncertainty
Uncertainty in conducted measurements ±1 dB
Uncertainty in radiated measurements ±6 dB
5.3 Methods of measurement
5.3.1 Generic methods of measurement
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
methods shall be used for all other receivers.
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
generators. It is necessary to provide calibrated attenuators for control of the individual levels; very often these will be
built into the generators. Where the attenuators are external, cable lengths should be kept short to avoid cross-coupling
effects.
The tests require the audio output of the receiver to be measured. All tonal controls (user operated and
