9 Test report
General requirements for compiling a test report taken from 5.10 of ISOIIEC 17025:2005. can be found in Annex F. Sufficient details shall be provided to facilitate reproducibility of the measurements. This shall include photographs of the measurement configuration for the formal measurements where this is appropriate.
The test report shall state the mode of operation of the EUT and how its ports were exercised
(see Annex B). The test report shall clearly indicate whether the product is compliant with the
Class A or Class B limits defined in Annex A.
For each relevant table clause in Annex A, the measurement results of at least the six highest emissions from the type of port being assessed relative to the limit, unless they are 10 dB or more below the limit, shall be recorded in the test report. Where a table clause includes more than one detector, the measurement results of these six emissions shall be recorded for each type of detector.1 The results shall include the following information for each of these emissions:
• the port assessed (Including enough information to identify it);
• for AC power line measurements the line under test, for example line or neutral;
• frequency and amplitude of the emission;
• margin with respect to the specified limit:
• the limit at the frequency of the emission;
• the detector used.
The report shall indicate if fewer than six emissions within 10 dB of the limit are observed.
NOTE It may also be beneficial to record en,lsslons 10 dB or more below the limit, In addition other aspects, such as antenna polarization or turntable azimuth, may be useful to record.
Additionally, the following shall be included in the test report:
• the frequency F of the highest internal frequency source within the EUT as defined in 3.1.19. This frequency need not be reported if radiated emissions are measured up to 6 GHz;
Further guidance is given in Annex F.
10 Compliance with this publication
Compliance with this publication requires that the EUT satisfies either the Class A or Class B requirements defined in Annex A, as appropriate. An EUT which fulfils the applicable requirements specified in Annex A is deemed to fulfil the requirements in the entire frequency range from 9 kl-lz to 400 GHz. No measurements need be performed at frequencies where no requirement is specified.
Where this publication gives options for testing particular requirements with a choice of test methods, compliance can be shown against any of the test methods using the appropriate limit. In any situation where it is necessary to re-test the equipment to show compliance with this publication, the test method originally chosen shall be used in order to guarantee consistency of the results, unless it is agreed by the manufacturer to do otherwise. Requirements for radiated emission measurements are defined in Table A.2 to Table A.6 with the restrictions and limitations defined in Table Al. Requirements for conducted emission measurements are defined in Table A.8 to Table A.12 with the restrictions defined in Table A.7.
The determination of compliance with this publication shall be based solely on contributions from the EUT For example, where an AE is required to exercise or monitor the EUT, and emissions from the AE are known to contribute to the overall measured emission of the system being assessed (for example an AE which is a plug-in module for the EUT), the AE selected should, wherever possible, be compliant with relevant emission limits. If the AE is known to cause significant emissions, these emissions may be reduced by mitigation measures, as long as these measures do not reduce the emissions from the EUT. The preferred configuration is that the AE is removed from the measurement area, as allowed by
0.1.
Compliance can be shown by measuring the EUT’s emissions when operating its functions simultaneously, individually in turn, or any combination thereof.
11 Measurement uncertainty
The measurement instrumentation uncertainty shall be calculated in accordance with CISPR 16-4-2 and reported as described In Clause 9,
Measurement instrumentation uncertainty shall not be taken into account in the determination of compliance. Refer to CISPRITR 16-4-3 for guidance on the applicability of the limits to a series produced MME.EN 55032-2012 pdf download.
