11 7. CARRIER POWER(CONDUCTED) The method of measurement described under EN ,subclause8.2.2 Note: Not applicable, This requirement applies to transmitters which may be used without an integral or dedicated antenna 8. EFFECTIVE RADIATED POWER The method of measurement described under EN ,subclause8.3.2 On a test site, selected from annex A, the equipment shall be placed at the specified height on a support, as specified in annex A, and in the position closest to normal use as declared by the manufacturer. The test antenna shall be oriented initially for vertical polarization and shall be chosen to correspond to the frequency of the transmitter. The output of the test antenna shall be connected to the measuring receiver. The transmitter shall be switched on, if possible, without modulation and the measuring receiver shall be tuned to the frequency of the transmitter under test. In case of pulse modulation equipment where it is not possible to make the measurement in the absence of modulation, the measurement shall be carried out by the use of a measuring receiver with bandwidth as stated in subclause 6.6 and peak detector set in accordance with the specification of CISPR 16 [8] section one for the bands C and D. The test antenna shall be raised and lowered through the specified range of height until a maximum signal level is detected by the measuring receiver. The transmitter shall then be rotated through 360 in the horizontal plane, until the maximum signal level is detected by the measuring receiver. The test antenna shall be raised and lowered again through the specified range of height until a maximum signal level is detected by the measuring receiver. The maximum signal level detected by the measuring receiver shall be noted. The transmitter shall be replaced by a substitution antenna as defined in annex A, subclause A.1.5. The substitution antenna shall be orientated for vertical polarization and the length of the substitution antenna shall be adjusted to correspond to the frequency of the transmitter. The substitution antenna shall be connected to a calibrated signal generator. If necessary, the input attenuator setting of the measuring receiver shall be adjusted in order to Page 11 of 22

12 increase the sensitivity of the measuring receiver. The test antenna shall be raised and lowered through the specified range of height to ensure that the maximum signal is received. The input signal to the substitution antenna shall be adjusted to the level that produces a level detected by the measuring receiver, that is equal to the level noted while the transmitter radiated power was measured, corrected for the change of input attenuator setting of the measuring receiver. The input level to the substitution antenna shall be recorded as power level, corrected for any change of input attenuator setting of the measuring receiver. The measurement shall be repeated with the test antenna and the substitution antenna orientated for horizontal polarization. The measure of the effective radiated power is the larger of the two levels recorded at the input to the substitution antenna, corrected for gain of the substitution antenna if necessary.

Please refer to clause 8.4 of EN TRANSIENT POWER The method of measurement described under EN The transmitter under test shall be connected via the power attenuator to the "transient power measuring device" as described in clause 8.5.3, so that the level at its input is suitable, e.g. between 0 dbm and -10 dbm when the transmitter power is the steady state power. The modulation test signal (see clause or as appropriate) shall be applied at the transmitter. For constant envelope modulation schemes it is not required to apply modulation. The modulation used, if any, shall be recorded in the test report. The measurement procedure shall be as clause 8.5 of EN Limits: EN ,subclause The transient power in the alternate channel shall not exceed a value of 40 db below the power of the transmitter without the need to be below 2 μw (-27,0 dbm). For measurements at 4 and 10 times the channel spacing the transient power shall not exceed 50 db below power of the transmitter without the need to be below 250 nw (-36 dbm). If the limit is exceeded the measurement in clause shall be repeated with the attenuator value reduced by 6 db to determine if transient effect is causing errors.

14 11. ADJACENT CHANNEL POWER The method of measurement described under EN ,subclause The adjacent channel power shall be measured with a power measuring receiver which conforms with the requirements given in annex B When using the test fixture (see subclause6.3) for this measurement, it is important to ensure that direct radiation from the transmitter to the power measuring receiver does not affect the result or the loss introduced by the testfixture. The following procedure shall be used: a) the transmitter under test shall be connected via the test load to a power measuring receiver calibrated to measure rms power level. The level at the receiver input shall be within its allowed limit. The transmitter shall be operated at the maximum operational carrier power level under normal conditions; b) the tuning of the power measuring receiver shall be adjusted away from the carrier so that its -6dB response nearest to the transmitter carrier frequency is located at a displacement from the nominal frequency of the carrier asgivenintable11. Table 11 Channel separation (khz) Displacement (khz) 10 5,75 12,5 8, The same result maybe obtained by tuning the power measuring receiver (point 0 in figure B.1 of the power measuring filter shape) to the nominal frequency of the adjacent channel,if it has been suitably calibrated. c) the transmitter shall be modulated as follows: -equipment for analogue speech and angle modulation shall be modulated with test signal A-M2 (see subclause6.1.1)at a level 20dB above the level of the normal test signal, or 10dB incase of a transmitter with an integrated microphone: (see sub clause 6.1.1)at a level which is 20dB higher than the level that is required to produce a modulation depth of 60%, or 10dB incase of a transmitter with an integrated microphone; -equipment using data streams shall be modulated with the test modulationd-m2(see subclause6.1.2)at the agreed deviation or modulation depth; -equipment for messages shall be modulated with the test modulationd-m3(see subclause6.1.2)repeated continuously at the agreed deviation or modulation depth. d) The absolute value of the adjacent channel power shall be recorded; e) Steps b)to d) shall be repeated with the power measuring receiver tuned to the other side of the carrier; f) The measurement shall be made under normal conditions and, if applicable, under extreme conditions (see clause8) Page 14 of 22
