Scope
本文件描述了高功率电磁瞬态响应参数测量的基本方法和主要设备。主要的响应参数包括以下内容:
——电场(E)和磁场(H)(例如:待测试系统的入射场或入射场与散射场的叠加场);
——电流I(例如:瞬态场感应的或待测系统内的);
——电压U(例如:瞬态场感应的或待测系统内的);
——在电缆或其他导体上的感应电荷Q。
注: 导体上的电荷Q是在任意频率下具有确定意义的一个基本量。然而,电压U是一个仅在低频情况下具有确定意义的(从属的)量。在高频情况下,电压不能由电场的线积分确定,因为这一积分依赖于路径。这样,对于上升沿很快的脉冲(具有大量的高频分量),采用电压作为测量量是不合适的,在这种情况下,需测量电荷量。
这些被测量通常是一些可以用标量参数或“可测参数”来近似描述的复杂时变波形,这些参数包括:
——响应的峰值;
——波形的上升时间;
——波形的下降时间(或持续时间);
——脉冲宽度;
——数学意义上由波形得到的范数。
本文件提供了这些波形的测量方法和特征参数的信息,但没有提供有关测量具体等级要求的信息。
