5.1.5 Disturbance analyzer for discontinuous disturbance：断续骚扰分析仪
The measuring equipment for discontinuous disturbance shall comply with Clause 10 of CISPR 16-1-1. An alternative method using an oscilloscope may be applied provided that the degree of accuracy is sufficient.
For the measurement of the duration of the disturbance, see CISPR 16-1-1.
断续骚扰的意外一个分析方法是用示波器，但是这对示波器有精度方面的要求，对操作人员的素质要求很高。现在几乎已经不用了。
模拟手啊，终于找到专业人士的解读了。。一直都不懂。
5.2 Measuring procedures and arrangements
5.2.1 Arrangement of the leads of the equipment under test
NOTE Clause 5 and Annex A of CISPR 16-2-1 give more information about the connection of the electrical appliances to the measuring equipment.
条款5.2主要是讲解测试时现场EUT布置的。内容比较详细。
5.2.1.1 Mains lead
During all measurements of disturbance terminal voltages (on the mains terminals or on other terminals) the artificial mains V-network is connected to the mains terminals in order to provide a defined termination. As described in detail in 5.2.2 the V-network is situated at a
distance of 0,8 m from the appliance.
5.2.1.1 电源线
在所有的端子电压（电源端子或其他端子）骚扰电压的测量中，V型人工电源网络应连接到电源端以提供一个规定的终端。如5.2.2中所述，V型网络的位置应与器具相距0.8m。
The disturbance voltage measurements are normally to be made at the plug end of the lead.
骚扰电压通常在引线的插头末端进行测量。
If the mains lead of the appliance under test is longer than necessary to be connected to the V-network the length of this lead in excess of 0,8 m shall be folded back and forth parallel to the lead so as to form a horizontal bundle with a length between 0,3 m and 0,4 m. In the case of controversy with regard to the banning of sales or withdrawal of a type approval it may be replaced by a lead of similar quality with a length of 1 m.
如果受试器具的电源引线超过连接到V型人工电源网络所需的长度，应将超过0.8m的导线部分，以平行于电源引线的方式折叠成一个长为0.3-0.4m之间的线束，如果有关于禁止销售或者取消形式认可方面的争论时，可用1m长的类似质量的引线代替电源引线。
If the lead on which the measurements are to be made is shorter than the required distance between the appliance and the mains V-network, it shall be extended to the necessary length.
如果所要测量的电源引线超过连接到V型人工电源网络之间要求的距离，引线应延长到规定的长度。
If the mains lead of the appliance under test includes the earthing conductor, the plug end of the earthing conductor shall be connected to the reference ground of the measuring equipment.
如果受试器具的电源引线有接地导线，接地导线的插头末端应与测量装置的参考地连接。
Where an earthing conductor is required, but is not included in the lead, the connection of the earth terminal of the appliance to the reference ground of the measuring equipment shall be made by a lead not longer than necessary to be connected to the V-network running parallel to the mains lead at a distance of not more than 0,1 m from it.
当需要接地导线，而接地导线又不包含在电源引线内时，应用导线将受试器具的接地端于测量装置的参考地连接，导线长度不超过连接到V型人工电源网络所需的长度，切导线应与导线引线平行，相距不超过0.1m。
If the appliance is not supplied with a lead it is to be connected to the artificial mains V-network by a lead not longer than 1 m (also in case of plug or socket-outlet).
如果器具没有提供电源引线，应用不超过1m的引线（包括插头和插座）讲器具与V型人工电源网络相连接。
针对5.2.1.1中电源引线的布置。
应该把握一个基本点：电源线的测量长度于V型人工电源网络的距离是0.8m。（为什么？现在还不清楚。）
布置现场时，要有以下的思路：
1、从电源线长度来看：分四种情况，有电源线，等于0.8m，小于0.8m，大于0.8m时电源线该怎么布置？如果没有电源线，应该怎么布置？
2、电源线接地与否：有接地导线，要怎么处理接地线？如果没有接地线，该怎么处理？
从应用的角度来说，把握了一个基本点，和上述的两个思路，对于EUT电源线的处理，就没有什么问题了。
5.2.1.2 Other leads
The lead connecting the appliance with an auxiliary apparatus and the leads to regulating controls or to batteries of battery-powered appliances shall be treated in accordance with 5.2.1.1 except where otherwise stated in this standard.
除非本部分中有其他描述，连接器具和辅助装置的引线和连接调节控制器或电池式器具电池的引线应该按照5.2.1.1处理。
针对除电源线外的其他导线：
标准中说的很明白，如果在标准中没有其他要求，和电源线的处理方式一样。因此，我们同样要把握好上述的一个基本点和两个思考点。
