    这一块的案例很贴切和生动。

    严格的操作是应该用类似性质的电源线剪断接在一起的。不过现在测试为了提高效率，接插排也是认为可以接受的。

    手机主要测试的应该是RTTE吧，这个现在在我们公司不归EMC业务线，具体的测试标准和项目我也不是很清楚，不好意思。

    在实际测量时，EUT的PE是接人工电源网络的地的。但是人工电源网络的地也是通过金属带连接到公共配电系统的地上的，参考接地平板也是通过金属带连接到公共配电系统上的。这样看的话，标准说的是没有错误的，只是需要在实际测试环境中去理解标准的意义，我想这就是为什么标准有时候难懂的一方面的原因吧

stone0371，感谢您的分享，大力的向您学习。

5.2.3 Appliances having auxiliary apparatus connected at the end of a lead other than the mains lead

在非电源线的引线端连接有辅助装置的器具

NOTE 1 Regulating controls incorporating semiconductor devices are excluded from this subclause, as these are covered in 5.2.4.

装有半导体器件的调节控制器不包含在此条内，这些器具包含在5.2.4中。

NOTE 2 When the auxiliary apparatus is not essential to the operation of the appliance and has a separate test procedure specified elsewhere in this standard (e.g. power nozzle of a vacuum cleaner) this subclause does not apply. The main appliance is tested as an individual appliance.

当辅助设备不是器具运行所必须得。并且在本部分中其他地方有规定的单独的测量程序（例如：真空吸尘器的动力吸管），本条不适用。主体器具作为独立器具进行测量。

Connecting leads exceeding 1 m in length are arranged in accordance with 5.2.1.1.
超过1m的连接引线按照5.2.1.1来布置。

Measurements need not to be made when the connecting lead between the appliance and the auxiliary apparatus is permanently fixed at both ends, and is either shorter than 2 m, or if it has a shielding whose ends are connected to the metal housing of the appliance and that of the auxiliary apparatus.

当器具和辅助装置之间的连接引线是永久地固定在二者的端部，且引线的长度短于2m，或者引线是屏蔽的，屏蔽引线端子连接在器具和辅助装置的金属外壳上，此种情况下不需要进行测量。

The measurement of the terminal voltage on non-rewirable leads longer than 2 m and shorter than 10 m shall be started at a frequency according to the following formula:

                                                        fstart = 60 / L
对于长于2m且短于10m的不可拆卸引线，其端子电压测量的起始频率应按照下述公式计算。

where
fstart is the start frequency for the measurement of the terminal voltage, in megahertz;
fstart：端子电压测量的起始频率，单位为兆赫兹（MHz）

L is the length of the connecting lead between the appliance and the auxiliary apparatus, in metres.
L：器具与辅助设备间连接引线的长度，单位为米（m）。


NOTE This calculation is based on the requirement that the length of the auxiliary lead shall not exceed one-fifth
of the wave length, corresponding to the start frequency of the measurement.
此计算公式是基于辅助引线不应超过测量的起始测量频率波长的五分之一的要求而规定的。

5.2.3.1 Measuring arrangement
测量布置

The equipment under test shall be arranged in accordance with 5.2.2 with the following additional requirements:

受试器具应按照5.2.2处理。并符合下列附加要求：

a) The auxiliary apparatus shall be placed at the same height and distance from the earthed conducting surface as the main appliance, and if the auxiliary lead is long enough, at a distance of 0,8 m from the main appliance, 5.2.1.1 shall be observed.
If the auxiliary lead is shorter than 0,8 m, the auxiliary apparatus shall be placed at the longest possible distance from the main apparatus.
辅助装置应象器具主体一样放置在与接地导电表面相同高度和相同距离处。如果辅助引线足够长，应放置在距离器具主体0.8m出，并参考5.2.1.1.
如果辅助引线短于0.8m，则辅助装置应放置在距器具主体尽可能远的距离。

If the auxiliary lead is longer than 0,8 m, the length of the auxiliary lead in excess of 0,8 m shall be folded parallel to itself so as to form a horizontal bundle with a length between 0,3 m and 0,4 m.
如果辅助引线长于0.8m，则超出0.8m部分的辅助引线应平行于本身折叠形成一个0.3m-0.4m间的水平线束。

The auxiliary lead is stretched in the opposite direction to the mains lead.
辅助引线应沿电源引线相反方向延伸。

When the auxiliary apparatus contains controls, the arrangements for its operation must not unduly affect the level of disturbance;
当辅助装置包含控制器时，其操作布置不能明显地影响骚扰电平。

b) If an appliance having an auxiliary apparatus is earthed, no artificial hand shall be connected. If the appliance itself is made to be held in the hand, the artificial hand shall be connected to the appliance and not to any auxiliary apparatus;
如果包含辅助装置的器具接地，则不应接模拟手。如果器具本身是手持式的，模拟手应接到器具上面而不能接到任何辅助装置上。

c) If the appliance is not made to be held in the hand, the auxiliary apparatus which is not earthed and is made to be held in the hand shall be connected to the artificial hand; if the auxiliary apparatus is not made to be held in the hand either, it shall be placed above an earthed conducting surface as described in 5.2.2.1.
如果器具不是手持式的，辅助装置不接地而且是手持式的，则不住装置应与模拟手连接；如果辅助装置也不是手持式的，应按照5.2.2.1的规定放在接地导电平面上。
