7.4.1 Continuous disturbance连续骚扰
7.4.1.1 The reading on the measuring receiver is observed for about 15 s for each measurement; the highest readings shall be recorded with the exception of any isolated spike which shall be ignored。
每次测量时观察接收机上的读数约15s，除了孤立的尖峰脉冲可以忽略以外，应记录最高的读数。
7.4.1.2 If the general level of the disturbance is not steady, but shows a continuing rise or fall of more than 2 dB in the 15 s period, then the disturbance measurement shall be performed in accordance with the conditions of normal use of the appliances, as follows:
如果总的骚扰电平是不稳定的，但在15s的期间内连续上升或下降大于2dB，则应在器具的正常使用条件下，按如下进行骚扰测量：
a) If the appliance is one which may be switched on or off frequently, for instance an electric drill or a sewing-machine motor, then at each frequency of measurement the appliance shall be switched on just before each measurement, and switched off just after each measurement; the maximum level obtained during the first minute at each frequency of measurement shall be recorded;
如果器具可以频繁地接通或断开，如电钻或缝纫机电动机，则在每一个频率点上，器具在每次测量前打开，测量后关闭；记录在每个测量频率点上的第一分钟内得到的最高电平；
b) if the appliance is one which in use normally runs for longer periods, for instance a hairdryer, then it shall remain switched on for the period of the complete measurement, and at each frequency the level of disturbance shall be recorded only after a steady reading (subject to the provision of 7.4.1.1) has been obtained.
如果器具在正常使用中运行较长时间，例如电吹风，则在整个测量期间，器具应保持在接通状态，在每个测量频率上只有获得稳定的读数（满足7.4.1.1条）后才记录骚扰电平。
7.4.1.3 The disturbance voltage limits apply throughout the frequency range 148,5 kHz to 30 MHz and therefore the disturbance characteristics shall be assessed throughout this frequency range.
骚扰电压限值适用于148.5kHZ-30MHz整个频段，因此应评定整个频段内的骚扰特性。
An initial survey or scanning of the complete range shall be made. In the case of quasi-peak detector measurement, the registered values shall be given at least at the following frequencies and at all frequencies at which there is a maximum:
160 kHz, 240 kHz, 550 kHz, 1 MHz, 1,4 MHz, 2 MHz, 3,5 MHz, 6 MHz, 10 MHz, 22 MHz, 30 MHz.
These frequencies are to be subject to a tolerance of ±10 %.
应在整个频段内进行初步观察或扫描，对于准峰值检波器测量，应至少在下列频率点和有最大骚扰的所有频率点上给出记录值：
160 kHz, 240 kHz, 550 kHz, 1 MHz, 1,4 MHz, 2 MHz, 3,5 MHz, 6 MHz, 10 MHz, 22 MHz, 30 MHz.
上述频率的容差为±10 %。
7.4.1.4 The disturbance power limits apply throughout the frequency range 30 MHz to 300 MHz and therefore the disturbance characteristics shall be assessed throughout this frequency range.
骚扰功率限值适用于30MHz-300MHz整个频段，因此应评定整个频段内的骚扰特性。
An initial survey or scanning of the complete range shall be made. In the case of quasi-peak detector measurement, the registered values shall be given at least at the followingfrequencies and at all frequencies at which there is a maximum:
30 MHz, 45 MHz, 65 MHz, 90 MHz, 150 MHz, 180 MHz, 220 MHz, 300 MHz.
These frequencies are to be subject to a tolerance of ±5 MHz.
应在整个频段内进行初步观察或扫描。对于准峰值检波器测量，应至少在下列频点和有最大骚扰的所有频率点上给出记录值：
30 MHz, 45 MHz, 65 MHz, 90 MHz, 150 MHz, 180 MHz, 220 MHz, 300 MHz.
这些频率的容差为±5 MHz。
这里补充说明一点：为什么会要求出现这些固定的频率点的数据？
我的看法是：在以前的测量接收机测量过程中，系统还不能自动扫描采集，需要手动操作，因此才有这些频率点的要求，现在都是集成系统自动扫描定位的，就没有必要规定这些要求了，可能在以后的标准修订中，这些频率点会删除。
7.4.1.5 If in the frequency range 30 MHz to 300 MHz measurements are made on a single appliance, the measurements are to be repeated on at least one frequency in the vicinity of each of the following frequencies:
45 MHz, 90 MHz, 220 MHz.
如果在30MHz-300MHz频段内测量时在单一器具上进行，应至少在下列每个频率点的附近的一个频率点上进行重复测量：
45 MHz, 90 MHz, 220 MHz.
