27、 Introduction: At the CISPR SC I plenary, held on the 27thOctober 2007, a decision was taken to set the maintenance date for CISPR 22, Edition 6 to 2012. As a result the work identified within CISPR/I/279/MCR will not be started for the time being. At the subsequent meeting of CISPR SC I WG3 it was

28、decided that certain items within the MCR would benefit now from further clarification and an interpretation sheet would be helpful to users of the standard, with the intent of including this information in a future amendment to the standard. This information does not change the standard; it serves

29、only to clarify the points noted. CISPR SC I WG3 hopes that these clarifications will be of use to users and especially laboratories testing to CISPR 22, Edition 6.0. The document is based on the comments received on CISPR/I/290/DC. Interpretation: 1. Selection of Average detector CISPR 22 defines l

30、imits for radiated emissions at frequencies between 1 GHz and 6 GHz with respect to both average and peak detectors. CISPR 16-1-1 defines two types of Average detector for use above 1 GHz. For the limits given in CISPR 22 the appropriate average detector is the linear average detector defined in 6.4

Measurement of conducted emissions on cabinets containing multiple items of equipment Where

32、the EUT is a cabinet or rack that contains multiple items of equipment that are powered from an AC power distribution strip and where the AC power distribution strip is an integral part of the EUT as declared by the manufacturer, the AC power line conducted emissions should be measured on the input

36、Report on voting CISPR/I/323/ISH CISPR/I/326/RVD Full information on the voting for the approval of this interpretation sheet can be found in the report on voting indicated in the above table. _ Introduction At the CISPR SC I plenary, held on the 27thOctober 2007, a decision was taken to set the mai

37、ntenance date for CISPR 22, Edition 6 to 2012. As a result the work identified within CISPR/I/279/MCR will not be started for the time being. At the subsequent meeting of CISPR SC I WG3 it was decided that 3 items within the MCR would benefit now from further clarification and an interpretation shee

38、t would be helpful to users of the standard, with the intent of including this information in a future amendment to the standard. The first draft of an interpretation sheet CISPR/I/290/DC addressed the 3 items, however it was clear from the comments received (CISPR/I/293A/INF) that further work was

39、required on the 3rditem related to ISN selection, and it was decided that this would be the subject of a separate document. This information does not change the standard; it serves only to clarify the points noted. CISPR SC I WG3 hopes that these clarifications will be of use to users and especially

40、 laboratories testing to CISPR 22:2008 (Edition 6.0). Selection of ISN for unscreened balanced multi-pair cables Subclause 9.6.3.1 of CISPR 22 states that: “When disturbance voltage measurements are performed on a single unscreened balanced pair, an adequate ISN for two wires shall be used; when per

41、formed on unscreened cables containing two balanced pairs, an adequate ISN for four wires shall be used; when performed on unscreened cables containing four balanced pairs, an adequate ISN for eight wires shall be used (see Annex D)” Therefore the selection of ISN is based on the number of pairs phy

42、sically in the cable, not the number of pairs actually used by the interface in question. BS EN 55022:2010Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 21/11/2011 07:13, Uncontrolled Copy, (c) BSI 2 April 2010 ICS 33.100.10 French text overleaf However, selection of a suitable ISN design fr

43、om the examples given in Annex D requires further consideration. The ISN designs given in Figures D.4 to D.7 are only appropriate for use where all of the balanced pairs in the cable are active and hence their use requires a more detailed knowledge of the EUT port being tested. The ISN designs given

44、 in Figures D.1 to D.3 have no such limitation and are better suited to applications where the actual use of the pairs is unknown. The ISN designs given in Figures D.2 and D.3 are also suitable for measurements on unscreened cables containing fewer balanced pairs than the maximum number of pairs the

45、 ISN is designed for (see example 2). The following definitions have been developed to help in determining what should be considered an active pair of conductors: An active pair is a pair of conductors that completes an active digital, analogue, or power circuit, or is terminated in a defined impeda

46、nce, or is connected to earth or the equipment frame/chassis. NOTE These circuits include such applications as “Power over Ethernet“. A circuit is an active circuit when it is in a state that is performing its intended function, which may include communications, voltage/current sensing, impedance ma

47、tching or power supply. NOTE A conductor with no intended function is not part of an active circuit. A measurement using an ISN described in Figures D.4 to D.7, when not all of the pairs are active, may result in a significant error in the measured emissions. It is therefore important that test labo

48、ratories determine on which of the designs given in the annexes their particular ISNs are based. From this they can then determine if they need to establish the number of active pairs within the cable or not and then whether their ISNs are suitable for the port being measured or whether an alternati

49、ve measurement technique needs to be used. This is applicable when measuring in accordance with 9.6.3.1 or 9.6.3.2. It is recommended that test reports should make reference to: the ISN category used; the Annex D figure corresponding to their particular ISN design; the total number of pairs in the cable and number of these that where active. Example 1: The EUT has an Ethernet port to which either a CAT 5 or 6 cable is connected. Typically these cables have four pairs requirin
