Class 2 locations are characterised by the existence o

19、ads are frequently switched; currents and associated magnetic fields are high. 6 Conditions during testing A minimum test configuration consists of two pieces of powerline communications equipment interconnected with manufacturer specified physical cable. Associated equipment necessary to the functi
20、on of the powerline network shall be included in the test configuration. The system shall be capable of transmitting and receiving data at the nominal transmission rate specified by the manufacturer. The powerline equipment shall execute a programme that exercises all the functions available to the
21、end user. As a minimum the functions described in Clause 7 of this standard Performance criteria shall be tested. EN 50412-2-1:2005 8 7 Performance criteria Performance criterion A During and after the test, the EUT shall operate without protocol failure, loss of link, any other loss of functions re
22、levant to the user, reduction in performance below that declared by the manufacturer. The manufacturer shall choose the most appropriate performance measurement criteria for their apparatus or system e.g. bit error rate, block error rate, throughput, re-transmissions etc. Performance criterion B Deg
23、radation of the performance beyond that as described in criterion A is permitted during the application of the test provided that the normal operation of the EUT is self-recoverable to the condition immediately before the application of the test. Performance criterion C Degradation of the performanc
24、e beyond that as described in criterion A is permitted during the application of the test provided that the normal operation of the EUT is self recoverable to the condition immediately before the application of the test or can be restored after the test by the operator. 8 Narrow band responses & rad
25、io-frequency continuous conducted tests This clause is applicable to Clause 10, Applicability, tests 3.1, 4.1, 5.1, 6.1, 7.1, 8.1 and 9.1 8.1 Tests on narrow band devices A narrow band device is defined as a device that uses a maximum of two simultaneous carriers e.g. one upstream and one downstream
26、 carrier. Narrow band devices shall benefit from exclusion bands in which radio-frequency continuous conducted common mode tests are not made. The exclusion bands are determined the same way for both the transmitter and the receiver of a device. Exclusion band definition for receivers or receivers w
27、hich are part of transceivers: Responses of receivers or the receiver part of (duplex) transceivers occurring during the immunity tests at discrete frequencies which are narrow band responses (spurious responses), are identified by the following method. If during the test, the immunity RF test signa
28、l causes non-compliance of the receiver with the specified performance criteria (see Clause 7), it is necessary to establish whether this non-compliance is due to a narrow band response or a wideband phenomenon. Therefore, the frequency of the test signal is increased by an amount equal to twice the
29、 nominal 6 dB bandwidth of the IF filter immediately preceding the demodulator of the receiver, or if appropriate, the bandwidth over which the apparatus is intended to operate, as declared by the manufacturer. The test is repeated with the frequency of the test signal decreased by the same amount.
30、9 EN 50412-2-1:2005 If the receiver is then in either or both frequency offset cases in compliance with the specified performance criteria, the response is considered as a narrow band response. If the receiver still does not comply with the specified performance criteria, this may be due to the fact
31、 that the offset has made the frequency of the unwanted signal correspond to the frequency of another narrow band response. Under these circumstances the procedure is repeated with an increase and decrease of the frequency of the test signal adjusted two and a half times the bandwidth referred to ab
32、ove. If the receiver still does not comply with the specified performance criteria in either or both frequency offset cases, the phenomena is considered wide band and therefore an EMC problem and the equipment fails the test. For immunity tests, narrow band responses shall be disregarded. It is reco
33、mmended that for narrow-band systems the manual should contain a warning that the equipment may be susceptible to interference. 8.2 Tests on broad band devices A broadband device is a device that uses 3 or more carriers simultaneously, OFDM, multicarrier modulation, spread spectrum technologies etc.
34、 Broadband devices shall not benefit from an exclusion band for the radio-frequency continuous conducted common mode tests. Broadband devices may incorporate adaptive algorithms that interact with the swept frequency test signal used for radio-frequency continuous conducted tests. Radio frequency in
35、gress, in practice, will typically be a combination of multiple single frequency fixed interferers and broadband noise. Consequently, the dwell time of the swept frequency test signal shall be chosen such that the apparatus or system performance is not adversely affected beyond that which would occu
36、r with a fixed or broadband interferer. 9 Product documentation The specification used by the manufacturer to define the performance criteria for the testing required by this standard shall be made available upon request. 10 Applicability Tests shall be applied to the relevant ports of the equipment
37、 according to Tables 1 to 9. Tests shall only be carried out where the relevant port exists. It may be determined from consideration of the electrical characteristics and usage of a particular equipment that some of the tests are inappropriate and therefore unnecessary. In such a case, it is require
38、d that both the decision and the justification not to apply any particular test to any particular port be recorded in the test report.
