27、 61326-1 applies. 5 EMC test plan 5.1 General IEC 61326-1 applies. 3 EN 61326-2-1:20065.2 Configuration of EUT during testing IEC 61326-1 applies, except as follows: Addition: 5.2.401 I/O ports for Test and Measurement purposes (T&M ports) Test and Measurement (T&M) input ports shall be capped and s
28、horted unless this leads to an operating condition unsuitable for measuring the emission and immunity performance of the product. In this case, an appropriate input signal shall be applied. Test and Measurement (T&M) output ports not needed to evaluate the essential functions of the EUT shall be cap
29、ped and/or terminated. NOTE 1 Probes and/or test leads to be used with the test and measurement ports do not need to be connected. Such test leads can vary substantially from one application to another and are often connected to equipment that has the covers removed and may be in various stages of d
30、isassembly 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 screen. 5.2.501 Auxiliary equipment Auxiliary equipment necessary for the normal operation of the equipment under
31、 test (EUT) shall be included as part of the equipment to be tested 5.3 Operation conditions of EUT during testing 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 Oscillos
32、copes The oscilloscope ports shall be 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
33、 modes during emissions testing and 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 (usuall
34、y auto-range, if available, will suffice) and continuous acquisition mode. 4 EN 61326-2-1:20065.3.105 Other equipment For equipment not mentioned in 5.3.102 to 5.3.104, the following philosophy shall apply.

35、 functions, 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 performance criteria IEC 61326-1 applies. 5.5 Test description IEC 61326-1 applies. 6 Immunity requirements 6.1 Condi
36、tions during the tests IEC 61326-1 applies. 6.2 Immunity test requirements IEC 61326-1 applies, except as follows: Addition: 6.2.101 Tests with transient electromagnetic phenomenon During testing, the EUT may have temporary degradation or loss of function or performance which is self-recovering. Sel
37、f-recovery times greater than 10 s shall be specified by the manufacturer. Trigger functions shall not be evaluated. No change in actual operating state or loss of stored data is allowed. Electrostatic discharges shall be applied to the housing shield, but not to the inner pins of shielded port or c
38、able connectors. Examples include: BNC, D-subminiature, IEEE 488 (GPIB), RS232 and IEEE 1284-B (parallel printer port), etc. 6.2.102 Tests with continuously present electromagnetic phenomenon No visual degradation of parameters of the EUT is allowed during application of the test, except as specifie
39、d by the manufacturer.

40、 width deviation, trace offset and display noise. 6.4.102 Logic analysers Typical parameters observed during immunity testing include logic analyser functional operations that may cause system lock-up or change of function or mode. 6.4.103 Digital multimeters (DMM) Typical parameters observed during
41、 immunity testing include the displayed measurement value. 7 Emission requirements IEC 61326-1 applies. 8 Test results and test report IEC 61326-1 applies. 9 Instructions for use IEC 61326-1 applies. 6 EN 61326-2-1:2006Bibliography IEEE 488, IEEE Standard For Higher Performance Protocol for the Stan
