ETSI ETSI EN 300 718-3 V1.2.1 (2004-02) 7 1 Scope The present
7、document applies to requirements for avalanche beacons. Avalanche beacons are portable radio systems used for locating avalanche victims, for the purpose of direct rescue, i.e. for rescue by comrades not hit by the avalanche. The present document is applicable for avalanche beacons operating on the
8、frequency 457 kHz. The present document is intended to cover the provisions of Directive 1999/5/EC (R Avalanche Beacons; Transmitter-receiver systems; Part 1: Technical characteristics and test methods“. 5 ETSI ETR 028 (Edition 2, 1994): “Radio Equipment and Systems (RES); Uncertainties in the measu
9、rement of mobile radio equipment characteristics“. 6 ITU Radio Regulations (1998), Appendix S1: “Classification of emissions and necessary bandwidths“. 7 ETSI EN 300 718-2 (V1.1.1, 2001): “Electromagnetic compatibility and Radio spectrum Matters (ERM); Avalanche Beacons; Transmitter-receiver systems

Where a unit of equipment provides a facility which is additional to requirements of the present do
11、cument, the operation or malfunction of such an additional facility shall not prevent the avalanche beacons conforming fully to the requirements of the present document during normal combined operation.

ETSI ETSI EN 300 718-3 V1.2.1 (2004-02) 116 Measurement uncertainties The accumulated measurement uncertainties of the test system in use for the parameters to be measured should not exceed those given in
16、 table 1. This is in order to ensure that the measurements remain within an acceptable uncertainty. Table 1: Parameter uncertainty Parameter Maximum uncertainty RF frequency 1 x 10-6Radiated emission of transmitter, valid up to 1 GHz (Substitution method) 2 dB Radiated emission of transmitter, valid
17、 up to 1 GHz (Direct measurement, using calibrated antennas) 6 dB Temperature 1C Humidity 5 % Transmitted H field at a distance of 10 m 0,1 A/m NOTE: Where applicable for the test methods according to the present document the uncertainty figures are valid to a confidence level of 95 % calculated acc
18、ording to the methods described in ETR 028 5. 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 requirem
19、ents 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 lower than the figures in table 1. For the test methods
20、, according to the present document, the measurement uncertainty figures shall be calculated in accordance with ETR 028 5 and shall correspond to an expansion factor (coverage factor) k = 1,96 of k = 2 (which provide confidence levels of respectively 95 % and 95,45 % in the case where the distributi
21、ons characterizing the actual measurement uncertainties are normal (Gaussian). Table 1 is based on such expansion factors.

22、e present document, ETSI grants that users of the present document may freely reproduce the EN-RT proforma in this annex so that it can be used for its intended purposes and may further publish the completed EN-RT proforma. The EN Requirements Table (EN-RT) serves a number of purposes, as follows: -
23、 it provides a tabular summary of all the requirements; - it shows the status of each EN-R, whether it is essential to implement in all circumstances (Mandatory), or whether the requirement is dependent on the supplier having chosen to support a particular optional service or functionality (Optional
24、). In particular it enables the EN-Rs associated with a particular optional service or functionality to be grouped and identified; - when completed in respect of a particular equipment it provides a means to undertake the static assessment of conformity with the EN. The EN-RT is placed in an annex o
25、f the EN in order that it may be photocopied and used as a proforma.
