34、ns Testing shall be made under normal test conditions, and also, where stated, under extreme test conditions. The test conditions and procedures shall be as specified in clauses 5.2 to 5.4. 5.2 External test power source During tests the power source of the equipment shall be an external test power
35、source, capable of producing normal and extreme test voltages. The internal impedance of the external test power source shall be low enough for its effect on the test results to be negligible. ETSI ETSI EN 302 066-1 V1.2.1 (2008-02) 10The test voltage shall be measured at the point of connection of
36、the power cable to the equipment. During tests the external test power source voltages shall be within a tolerance of 1 % relative to the voltage at the beginning of each test. The level of this tolerance can be critical for certain measurements. Using a smaller tolerance provides a reduced uncertai
37、nty level for these measurements. 5.3 Normal test conditions 5.3.1 Normal temperature and humidity The normal temperature and humidity conditions for tests shall be any convenient combination of temperature and humidity within the following ranges: temperature: +15 C to +35 C; relative humidity: 20
38、% to 75 %. When it is impracticable to carry out tests under these conditions, a note to this effect, stating the ambient temperature and relative humidity during the tests, shall be added to the test report. 5.3.2 Normal test power source The internal impedance of the test power source shall be low
39、 enough for its effect on the test results to be negligible. For the purpose of the tests, the voltage of the external test power source shall be measured at the input terminals of the equipment. 5.3.2.1 Regulated lead-acid battery power source The normal test voltage for equipment shall be a regula
40、ted lead-acid battery power source. For the purpose of the present document, the nominal voltage shall be the declared voltage, or any of the declared voltages, for which the equipment was designed. When the radio equipment is intended for operation with the usual types of regulated lead-acid batter
41、y power source, the normal test voltage shall be 1,1 multiplied by the nominal voltage of the battery (e.g. 6 V, 12 V, etc.). 5.3.2.2 Other power sources For operation from other power sources or types of battery (primary or secondary), the normal test voltage shall be that declared by the provider.
42、 Such values shall be stated in the test report. 5.4 Extreme test conditions 5.4.1 Extreme temperatures 5.4.1.1 Procedure for tests at extreme temperatures Before measurements are made the equipment shall have reached thermal balance in the test chamber. The equipment shall not be switched off durin
43、g the temperature stabilizing period. If the thermal balance is not checked by measurements, a temperature stabilizing period of at least one hour, or such period as may be decided by the test laboratory, shall be allowed. The sequence of measurements shall be chosen, and the humidity content in the
44、 test chamber shall be controlled so that excessive condensation does not occur. ETSI ETSI EN 302 066-1 V1.2.1 (2008-02) 115.4.1.2 Extreme temperature ranges For tests at extreme temperatures, measurements shall be made in accordance with the procedures specified in clause 5.4.1.1, at the upper and
45、lower. temperatures of one of the following limits: temperature: -20 C to +55 C 5.4.2 Extreme test source voltages 5.4.2.1 Regulated lead-acid battery power source The extreme test voltages for equipment shall be the nominal voltage 10 %. 5.4.2.2 Other power sources For equipment using other power s
46、ources, or capable of being operated from a variety of power sources, the extreme test voltages shall be that declared by the provider. These shall be recorded in the test report. 5.5 Combined equipment When GPR/WPR is part of a combined equipment refer to the guidelines set out in TR 102 070-2 4. 6
47、 General conditions 6.1 Radiated measurement arrangements Detailed descriptions of the radiated measurement arrangements are included in annex A. In general, measurements shall be carried out under far field conditions. The far field condition for the EUTs is considered to be fulfilled in a minimum
48、radial distance “X“ that shall be a minimum of 2d2/ , where d = largest dimension of the antenna aperture of the EUT, for a single device measurement. Absolute power measurements shall be made using an appropriate method to ensure that the wave front is properly formed (i.e. operating in far field c
49、onditions). The test site shall meet the appropriate requirements as defined in published guidelines/standards. It may not be possible to measure at the power limits without low-noise amplification to reduce the overall noise figure of the overall measurement system at a separation of approximately 3 meters in an RF quite environment. A lower separation distance may be required since the instrumentation noise floor should be at least 10 dB above the limit within the instrument bandwidth. 6.2 Measuring receiver The term measuring receiver refer
