33、t related test conditions for digital cellular mobile and portable radio equipment are specified in the present document. 4.1 General For emission and immunity tests the test modulation, test arrangements, etc., as specified in the present document, clauses 4.1 to 4.5, shall apply. Whenever the Equi
34、pment Under Test (EUT) is provided with a detachable antenna, the EUT shall be tested with the antenna fitted in a manner typical of normal intended use, unless specified otherwise. 4.2 Arrangements for test signals The provisions of EN 301 489-1 1, clause 4.2 shall apply. 4.2.1 Arrangements for est
35、ablishing a communications link The nominal frequency of the wanted RF input signal (for the receivers) shall be selected by setting the Absolute Radio Frequency Channel Number (ARFCN) to an appropriate number (e.g. in case of GSM 900 MHz this is 60 to 65, and in case of GSM 1 800 MHz this is 690 to
36、 706). A communication link shall be set up with a suitable base station simulator (hereafter called “the test system“). When the EUT is required to be in the transmit/receive mode, the following conditions shall be met: - the EUT shall be commanded to operate at maximum transmit power; - the downli
37、nk RXQUAL shall be monitored. 4.2.1.1 Calibration of the overall audio link performance Prior to the test sequence, the reference level of the speech output signal on both the downlink and uplink shall be recorded on the test instrumentation, as shown in figure 1. If the equipment does not include a
38、coustical transducers (e.g. a microphone or loudspeaker) the equivalent electrical reference levels shall be specified by the manufacturer. The voice processor may often apply noise and echo cancellation algorithms which attempt to eliminate or reduce steady state audio signals as e.g. the 1 kHz cal
39、ibration signals. The calibration should be carried out with the noise and echo cancellation algorithms disabled. (Specific test software may be required). If the noise and echo cancellation algorithms cannot be disabled then the reference level of the speech output signal should be measured using a
40、 max-hold detection on the audio level meter in order to determine the level before the noise and echo cancellation algorithms become effective. ETSI ETSI EN 301 489-7 V1.3.1 (2005-11) 9 Calibration of the downlink: The EUT is not used for the calibration of the downlink. Adjust the output of the au
41、dio test source to achieve a reference level equivalent to a SPL of 0 dBPa at 1 kHz at the input of the acoustic coupler (tube in figure 1) for the downlink. Record the reading of the audio level meter as the reference level. If in handsfree applications an external loudspeaker is used, the SPL from
42、 the external loudspeaker is higher than that from the earpiece of the portable by a certain amount in order overcome a high ambient noise level. Two methods can be used to achieve the required SPL: - the downlink reference level shall be increased by the same amount in order to compensate for the d
43、ifference in SPL; or - the distance between the loudspeaker and the measuring microphone shall be adjusted during the measurement procedure resulting in the required SPL. It is important that the dynamic range of the test instrumentation is not exceeded. Calibration of the uplink: For the calibratio
44、n of the uplink the EUT is used. Adjust the output of the audio test source to achieve a reference level equivalent to a SPL of -5 dBPa at 1 kHz at the Mouth Reference Point (MRP) defined in ITU-T Recommendation P.64 8. Record the reading of the audio level meter, which is connected to the output of
45、 the test system, as the reference level. For handsfree applications, normally no corrections are made to the uplink reference level. If it is not possible to perform the above calibration (e.g. a PC card with headset) the manufacturer shall specify the distance between the MRP and the microphone. I
46、t is important that the dynamic range of the test instrumentation is not exceeded. NOTE: The MRP is defined with respect to an artificial head defined in ITU-T Recommendation P.64 8). The handset shall be mounted on the artificial head such that the ear piece is centred at the artificial ear. Both r
47、ecorded levels (downlink and uplink) are used as reference levels for the performance assessment (see clauses 6.1 and 6.3).

48、test source NOTE: The EUT is in position during calibration of the uplink, but not during calibration of the downlink where the EUT is replaced by the 1 kHz test audio source. During calibration of the uplink the mouthpiece shall be placed with respect to the MRP in a way representing intended use.

When the audio levels are measured during testing the EUT software shall be configured for voice applications. If the algorithms for noise and echo cancellation are not disabled, t
