ETSIEN 300 734 V1.1.1 (1998-04)15For each of the transmit frequencies to be used for the test, measurements shall be made over the frequency ranges from1 978,1 MHz to fc - a and from fc + b to 2 011,9 MHz, fc-a being the lower boundary frequency of the Bn for thetransmit frequency being tested, and fc + b being the upper boundary frequency of the Bn for the transmit frequencybeing tested.6.4Test requirementsFor measurements of radiated unwanted emissions of the MES, the measured values shall in no case exceed the limitsgiven in tables 3 or 4, as applicable, over the frequency range 1 978,1 to 2 011,9 MHz.For measurements of conducted unwanted emissions, the measured values plus the maximum antenna gain, shall in nocase exceed the limits given in tables 3 or 4, as applicable, over the frequency range 1 978,1 to 2 011,9 MHz.7Unwanted emissions in carrier-off state7.1PurposeProtection of other radio services and systems from unwanted emissions caused by MESs in the carrier–off state.7.2Conformance requirementsThe maximum EIRP of the unwanted emissions from the MESs in the carrier-off state shall not exceed the limits intable 5.In table 5, whenever a change of limit between adjacent frequency bands occurs, the lower of the two limits shall applyat the transition frequency.Table 5: Maximum EIRP of the unwanted emissions in the carrier-off stateFrequency(MHz)EIRP(dBW)MeasurementbandwidthMeasurementmethod0,1 - 30-8710 kHzpeak hold30 - 1 000-87100 kHzpeak hold1 000 - 12 750-77100 kHzpeak holdThe conformance requirements apply for the full range of environmental conditions corresponding to the type ofequipment as specified in clause B.2.7.3Method of testThe MES shall be switched-on and set in a non-transmitting (carrier-off) mode.If there is a periodic automatic transmission of bursts (e.g. for location updating), the STE shall provide a means toinhibit it, or to trigger the measurement in order to analyse only the non-transmitting periods.The environmental test conditions are given in clause B.3.In the test equipment, the spectrum analyser noise floor shall be at least 6 dB below the appropriate limits given intable 5.The measurements are performed with the radiated or with the conducted method according to the cases defined insubclause A.5.For measurements of radiated unwanted emissions, annex C applies.For measurements of conducted unwanted emissions, annex D applies.SIST EN 300 734:2000
ETSIEN 300 734 V1.1.1 (1998-04)167.3.1Measurement methodThe spectrum analyser shall be set in sweep mode and shall be operated under the following conditions:frequency sweep:as required for frequency range to be assessed;resolution bandwidth:measurement bandwidth specified in table 5;display bandwidth:at least 3 times the measurement bandwidth;averaging:no;peak hold:yes.The sweep time shall be the shortest possible time consistent with proper calibration and ease of operation.The spectrum analyser shall be stepped over the frequency ranges specified.7.4Test requirementsFor measurements of radiated unwanted emissions of the MES, the measured values shall in no case exceed the limitsgiven in table 5.For measurements of conducted unwanted emissions of the MES, the measured values plus the maximum antenna gainshall in no case exceed the limits given in table 5.8MES Control and Monitoring Functions (CMF)8.1Special Test Equipment (STE)Many of the tests in this subclause require that the MES be situated in an environment where receipt of a networkcontrol channel and of NCF commands is controlled by the test laboratory. This will require the provision by theapplicant of STE (see clause A.2). This STE shall provide the means to generate and to communicate to the MES, eitherradiated via its antenna or conducted via direct connection to its antenna port, the network control channel and therequired NCF commands, under the control of the test laboratory. The STE shall also provide means for the testlaboratory to interface its test equipment with the MES for the purpose of monitoring the MES responses.8.2Self-monitoring functions8.2.1Processor monitoring8.2.1.1PurposeProtection of radio services and systems from uncontrolled RF transmissions from the MES.SIST EN 300 734:2000
