5 Testing for compliance with technical requirement s 
5.1 Environmental conditions for testing 
Tests defined in the present document shall be carr ied out at representative points within the 
boundary limits of the declared operational environ mental profile. 
Where technical performance varies subject to envir onmental conditions, tests shall be carried 
out under a sufficient variety of environmental con ditions (within the boundary limits of the 
declared operational environmental profile) to give  confidence of compliance with the affected 
technical requirements.  
5.1.1 Normal and extreme test conditions 
Measurements shall be made under normal test condit ions, and also, where stated, under

The test conditions and procedures shall be as spec ified in EN 300 086-1 [1], clauses 5.3 to 5.5. 
5.1.2 Test power source 
The test power source shall meet the requirements o f EN 300 086-1 [1], clause 5.2. 
5.1.3 Nominal input test signal 
The nominal input test signal (applied to the input  of the repeater) is a modulated test signal 
(modulation frequency shall be 1250 Hz and resultan t frequency deviation shall be 60 % of the 
maximum permissible frequency deviation according E N 300 086-1 [1] clause 7.4.3.1) which level 
is adjusted to produce a nominal output power level  (measured at the output of the repeater) as 
defined by the manufacturer. 
5.1.4 Choice of samples for test suites 
Measurement shall be performed, according to the pr esent document, on samples of equipment 
defined in EN 300 086-1 [1], clause 4.1. 
5.2 Interpretation of the measurement results 
The interpretation of the results recorded in a tes t report for the measurements described in the 
present document shall be as follows: 
• the measured value compared to the corresponding l imit shall be used to decide whether 
an equipment meets the requirements of the present document; 
• the value of the measurement uncertainty for the m easurement of each parameter shall 
be included in the test report; NT-3002 
 
1000219862 9/13 
 • the value of the measurement uncertainty shall be,  for each measurement, equal to or 
lower than the figures given in clause 10 (table 13 ) in EN 300 086-1 [1]. 
For the test methods, according to the present docu ment, the measurement uncertainty figures 
shall be calculated in accordance with TR 100 028 [ 1] and shall correspond to an expansion 
factor (coverage factor) k = 1,96 or k = 2 (which p rovide confidence levels of respectively 95 % 
and 95,45 % in the case where the distributions cha racterizing the actual measurement 
uncertainties are normal (Gaussian)). 
The particular expansion factor used for the evalua tion of the measurement uncertainty shall be 
stated. 
The absolute measurement uncertainties are given in  clause 10 (table 13) in EN 300 086-1[1].  
5.3 Essential radio test suites 
Essential test suites are referred to in annex III of TIO [l.2] (or annex III of R&TTE Directive [i.1] ). 
The following essential test suites shall be used t o assess the performance of equipment. 
5.3.1 Frequency error 
The frequency error shall be measured to determine the difference between the measured carrier 
frequency in the absence of modulation and the nomi nal frequency of the transmitter. 
This test applies only to frequency changing repeat ers. 
The measurements specified in EN 300 086-1 [1], cla use 7.1.2 shall be carried out. 
5.3.2 Adjacent and alternate channel power 
The adjacent and alternate channel power shall be m easured to determine the part of the total 
power output of a repeater under defined conditions  of modulated input signal, which falls within a 
specified pass-band centred on the nominal frequenc y of either of the adjacent and alternate 
channels. This power is the sum of the mean power p roduced by the modulation, hum and noise 
of the repeater. 
This test applies only to channel selective repeate rs. 
The repeater shall be set to maximum gain. The meas urements specified in EN 300 086-1 [1], 
clause 7.5.2 shall be carried out. The input test s ignal for this test shall be as defined in accordin g 
NT-3002, clause 5.1.3.  
5.3.3 Intermodulation attenuation 
This test shall be used to verify that the level of  intermodulation products, generated in non-linear 
elements of the repeater, in the presence of two RF  input signals, do not exceed the specified 
limits. 
This requirement applies to all types of repeaters.  
The repeater shall be set to maximum gain. Two cont inuous sinusoidal RF signals shall be fed to 
the input antenna port of the repeater using a comb ining device. The frequencies of both RF 
signals shall be within the repeater's operating ba nd. The spacing between both RF signals shall 
be lower than the declared operational frequency ba nd of the repeater (e.g. 500 kHz). The input 
signals and resulting third order product shall be within the declared operational frequency band 
of the repeater. 
The level of both RF input signals shall be increas ed, until the maximum rated output power, as 
declared by the manufacturer, is reached. 
In case of a repeater only supporting one channel, one RF input signal shall be set to the 
operating frequency and the other RF input signal a t an offset of 100 kHz to either side NT-3002 
 
1000219862 10/13 
 successively. In this case the input signal at the repeaters operating frequency shall be 
increased, until the maximum rated output power per  channel, as declared by the manufacturer, 
is reached. The second signal shall be set to the s ame input level. 
The level of the third order intermodulation produc ts shall be measured by means of a selective 
measurement device presenting to the repeater a loa d with an impedance of 50 Ω. 
The test shall be repeated with both RF input signa ls increased by 10 dB each. 
NOTE: In this case, the automatic gain (level) cont rol may reduce the gain to a value less than 
maximum gain in order to keep the maximum rated out put power per channel, as declared by 
the manufacturer. An average power measurement shal l be performed using a bandwidth of 3 
kHz. 
The measurements shall be performed on all antenna ports of the repeater. 
5.3.4 Spurious emissions and Wideband noise 
The purpose of this test is to establish the level of conducted spurious emissions and wideband 
noise at the antenna ports and the effective power of spurious emissions radiated by the cabinet 
and structure. 
This requirement applies to all types of repeaters.  
The measurements specified in TS 101 789-1 [3], cla use 5.5.1 shall be carried out under normal 
test conditions. Measurement bandwidths shall be as  indicated in table 1 and 2:

9 kHz to 150 kHz 1 kHz 
150 kHz to 30 MHz 10 kHz

5.3.5 Out of band gain 
To test the net gain of the repeater outside the de clared transmit frequency band. This test shall 
also be used to check the net gain at harmonic freq uencies. 
This requirement applies to all types of repeaters.  
The measurements specified in TS 101 789-1 [3], cla use 5.5.3 shall be carried out, under normal 
test conditions.
