DONGGUAN CITY FLYSKY REMOTE MODEL CO., LTD.MODEL: FS-TH9XThe test antenna shall be oriented initially for vertical polarization and shall be chosen to correspond to thefrequency 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 tothe frequency of the transmitter under test.In case of pulse modulation equipment where it is not possible to make the measurement in the absence ofmodulation, the measurement shall be carried out by the use of a measuring receiver with bandwidth as stated insubclause 6.6 and peak detector set in accordance with the specification of CISPR 16 [8] section one for the bandsC and D.The test antenna shall be raised and lowered through the specified range of height until a maximum signal level isdetected by the measuring receiver.The transmitter shall then be rotated through 360° in the horizontal plane, until the maximum signal level isdetected by the measuring receiver.The test antenna shall be raised and lowered again through the specified range of height until a maximum signallevel 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 antennashall 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 increase thesensitivity of the measuring receiver.The test antenna shall be raised and lowered through the specified range of height to ensure that the maximumsignal is received.The input signal to the substitution antenna shall be adjusted to the level that produces a level detected by themeasuring receiver, that is equal to the level noted while the transmitter radiated power was measured, correctedfor 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 inputattenuator setting of the measuring receiver.The measurement shall be repeated with the test antenna and the substitution antenna orientated for horizontalpolarization.The measure of the effective radiated power is the larger of the two levels recorded at the input to the substitutionREPORT NO.: STR07108045E-1 PAGE 8 OF 29 EN 300 440-1 EN 300 440-2
