EUI should be tested under normal test environment. The test conditions shall be recorded in the report. GB 19484,1—2004
When the EUT has a detachable integrated mains cable, unless otherwise specified in this standard, the mains cable shall be installed in the manner of normal use for testing.
The test arrangement shall be as close as possible to the normal or typical actual operating conditions. If the ELT is part of the system or connected to auxiliary equipment, then during the test, the ELT shall be connected to the auxiliary equipment with the minimum typical configuration, and the ports connected to the auxiliary equipment must be activated. The operating mode and configuration must be accurately recorded in the test report during the test. If the equipment has a large number of ports, a sufficient number of ports must be selected to ensure that the actual situation can be simulated and different types of ports can be tested.
4.2 Standard test power supply
4.2.1 Standard DC voltage when powered by multiple batteries The standard test DC voltage is equal to the nominal working voltage of the FUT. When powered by multiple batteries in series, the test voltage is equal to the power supply voltage of each battery multiplied by the number of batteries used, minus the average loss of the power supply line. The battery may be charged or discharged during the operation of the ELT. Therefore, the ELT is tested for the limit voltage. In the series test of a test item selected for the ELT, the test voltage should not deviate from the standard test voltage by 1%. 4.2.2 Standard AC voltage and frequency
The standard AC voltage during the test of the EUT powered by AC power is equal to the nominal voltage of the EUT specification 5, and its frequency and voltage value should not deviate from its nominal value by 2%.
When the power supply voltage deviates from the rated voltage by ±10, the EUT operates normally and there is no performance degradation. 4.3 Test arrangement
4.3.1 Transmitter input port test arrangement
Generate an appropriate normal modulation signal through an internal or external signal source and enter the transmitter input port. The external signal source must be outside the test environment.
4.3.2 Test arrangement of transmitter output port
SS should be placed outside the test environment.
For integrated antenna equipment, the useful signal for establishing communication connection should be fed from EUT to the antenna located in the test environment: For non-integrated antenna equipment: The useful signal for establishing communication connection should be fed from the antenna connector of EUT and connected to SS using a suitable shield cable. Appropriate measures should be taken to reduce the influence of interference signals on the test equipment. 4.3.3 Test arrangement of receiver input port
SS should be placed outside the test environment.
For integrated wireless equipment, the useful signal for establishing communication connection should be fed from the antenna located in the test environment. For non-integrated wireless equipment: The useful signal for establishing communication connection should be fed from the antenna located in the test environment using a suitable shield cable. Appropriate measures should be taken to avoid the influence of interference signals on the test equipment. During the immunity test, the wanted RF input signal for the communication link shall be greater than the reference sensitivity level of the ELT, but not more than 10 dB. During the interference measurement 1, the wanted RF input signal shall not exceed the reference sensitivity level by 15 dB. 4.3.4 Receiver output port test arrangement For speech equipment, the full-frequency output of the receiver shall be connected to an audio distortion analyzer or other similar measuring instrument located outside the test environment through a non-conductive acoustic tube. In cases where a non-conductive acoustic tube cannot be used, other methods may be used to connect the receiver output to an audio distortion analyzer or other similar measuring instrument and the results shall be recorded in the test report. For non-speech equipment, the receiver output signal shall be connected to the test equipment located outside the test environment through a non-conductive acoustic tube. If the receiver has a receiver output connector or port, it shall be connected to the test equipment located outside the test environment by a cable as in the normal operation of the FIT. Precautions shall be taken to minimize the effect of coupling on the test results. 4.4 Exempted frequency band
Exempted frequency band refers to the frequency band where the radiation immunity test is not performed. Range: 867.5MHz～895.5MHz. 4.5 Narrowband response of receiver
The narrowband response generated by the receiver and the transmitter/receiver at discrete frequencies in the immunity test is determined by the following methods: a) In the immunity test, if the performance index deviates from the requirements of the sixth competition. It is necessary to determine the cause of the index deviation. Both narrowband response and wideband phenomenon may cause the signal index deviation. In this case, further judgment is made: b) Increase or decrease the test frequency by 2.5MHz, repeat the test, if the signal index deviation disappears, this is a narrowband response:
If the signal index deviation does not disappear, it may be a narrowband response caused by an interference signal. In this case, increase or decrease the test frequency by 3.125MHz and repeat the test: b) If the signal deviation still disappears, it is considered to be a broadband phenomenon. That is, the EUT fails the test. The band-drop response should be ignored:
4.6 Immunity test conditions and layout
The immunity test is carried out in two operating modes: a) talk mode;
b) idle mode
When the EUT is in talk mode, the following conditions should be met: a) the maximum input power;
DTX of the ET is prohibited:
e) power control is prohibited;
d) the bit rate of the forward/reverse channel is the normal rate. Appropriate measures should be taken to avoid the influence of the RF signal of the immunity test on the test equipment. When conducting the immunity test, the FU should establish a communication connection with the SS. The transmitter operates at the maximum output power and adopts positive band test modulation. The useful input signal to the receiver should adopt normal test modulation. When the EUT is required to be in transmit/receive mode, the following conditions shall be met: a) The EUT is operated at maximum transmit power: 1) Monitor the FFR of the EUT; c) As shown in Figure [, before testing, the reference level of the forward link and reverse link audio output signals shall be recorded in the test instrument. For the forward link, the reference level is equivalent to 0dRPa at 1kHz at FRP, and for the reverse link, it is equivalent to -5 BPe at 1kHz at MRF. Set the EUT audio to the rated volume or medium volume + GB 19484.1—2004
d) As shown in Figure 2, the level of the voice channel output signal of the EUT forward link at ERI should be evaluated by measuring SFL: e) Measure the decoded signal level of the EUT reverse voice channel output at the analog output port of SS. The external background noise picked up by the differential wind of the EUT should be minimized during the immunity test. Note: If the FVT does not contain analog voice circuits, it is not evaluated by the voice signal level. Anechoic chamber
