29、ons, operational conditions and performance criteria for sensitive test and measurement equipment for EMC unprotected applications 1 Scope In addition to the scope of IEC 61326-1, this part of IEC 61326 specifies more detailed test configurations, operational conditions and performance criteria for

30、equipment with test and measurement circuits (both internal and/or external to the equipment) that are not EMC protected for operational and/or functional reasons, as specified by the manufacturer. The manufacturer specifies the environment for which the product is intended to be used and selects th

31、e appropriate test level specifications of IEC 61326-1. NOTE Examples of equipment include, but are not limited to, oscilloscopes, logic analysers, spectrum analysers, network analysers, analogue instruments, digital multimeters (DMM) and board test systems. 2 Normative references The following docu

32、ments, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. Clause 2 of IEC 61326-1 a

34、General Clause 4 of IEC 61326-1 applies. 5 EMC test plan 5.1 General Subclause 5.1 of IEC 61326-1 applies. BS EN 61326-2-1:2013 6 61326-2-1 IEC:2012 5.2 Configuration of EUT during testing Subclause 5.2 of IEC 61326-1 applies, except as follows: Addition: 5.2.4.101 I/O ports for test and measurement

35、 purposes Test and measurement input ports shall be capped and shorted unless this leads to an operating condition unsuitable for measuring the emission and immunity performance of the product. If an input signal is needed, an appropriate input signal shall be applied using test leads or probes as s

36、pecified by the manufacturer. Test and measurement output ports not needed to evaluate the essential functions of the EUT shall be capped and/or terminated. Electrostatic discharges shall be applied to the housing shield, but not to the inner pins of shielded port or cable connectors. Examples inclu

37、de: BNC, D-subminiature, IEEE 488 (IEC 60488), RS232 and IEEE 1284-B (parallel printer port), etc. NOTE 1 Probes and/or test leads not used to apply an input signal during test to the test and measurement ports do not need to be connected. Such test leads can vary substantially from one application

38、to another and are often connected to equipment that has the covers removed and may be in various stages of disassembly to provide access to test points inside. Connected test leads may increase emissions and/or reduce immunity in certain applications. NOTE 2 Capped means locally covered with a scre

39、en or shield. 5.3 Operation conditions of EUT during testing Subclause 5.3 of IEC 61326-1 applies, except as follows: Addition: 5.3.101 Operational conditions When both battery and a.c. options are available, both modes of operation shall comply. 5.3.102 Oscilloscopes The oscilloscope ports shall be

40、 set for maximum sweep speed, maximum sensitivity and continuous acquisition mode unless other modes are known to provide worst-case emission or immunity results within normal applications. 5.3.103 Logic analysers The logic analyser shall be set for data analysis modes during emission measurement an

41、d continuous data acquisition mode during immunity testing unless other modes are known to provide worst-case emission or immunity results within normal applications. 5.3.104 Digital multimeters (DMM) Typical set-ups include: peak detect, maximum sensitivity (usually auto-range, if available, will s

42、uffice) and continuous acquisition mode. 5.3.105 Other equipment For equipment not mentioned in 5.3.102 to 5.3.104, the following philosophy shall apply. BS EN 61326-2-1:201361326-2-1 IEC:2012 7 A selection of representative operation modes shall be made, taking into account that not all functions,

43、but only the most typical functions of the equipment can be tested. The estimated worst-case operating modes for normal application shall be selected 5.4 Specification of functional performance Subclause 5.4 of IEC 61326-1 applies. 5.5 Test description Subclause 5.5 of IEC 61326-1 applies. 6 Immunit

44、y requirements 6.1 Conditions during the tests Subclause 6.1 of IEC 61326-1 applies. 6.2 Immunity test requirements Subclause 6.2 of IEC 61326-1 applies. 6.3 Random aspects Subclause 6.3 of IEC 61326-1 applies. 6.4 Performance criteria Subclause 6.4 of IEC 61326-1 applies, except as follows: Additio

45、n: 6.4.101 Tests with transient electromagnetic phenomenon During testing with transient electromagnetic phenomena that are assigned to performance criteria B in Table 1, 2 or 3 of IEC 61326-1, the EUT may have temporary degradation or loss of function or performance which is self-recovering. Self-r

46、ecovery times greater than 10 s shall be specified by the manufacturer in the equipment documentation for the user. Trigger functions need not be evaluated. No change in actual operating state or loss of stored data is allowed. 7 Emission requirements Clause 7 of IEC 61326-1 applies. 8 Test results

47、and test report Clause 8 of IEC 61326-1 applies. 9 Instructions for use Clause 9 of IEC 61326-1 applies, except as follows: Addition: BS EN 61326-2-1:2013 8 61326-2-1 IEC:2012 9.101 Additional instructions The manufacturer shall give information that the equipment may not meet the immunity requireme

48、nts of this standard when test leads and/or test probes are connected and shall give guidance how to use test leads and/or test probes to minimize the impact of disturbances. _ BS EN 61326-2-1:2013This page deliberately left blankThis page deliberately left blankBSI is the independent national body
