摘　　要：车外源辐射抗扰性试验已经成为国内汽车电磁兼容实验室必须具备的试验能力之一。通过理论分析和实际测量,对200～1 000 MHz频率范围内达到不同严酷电平需要的功率进行了估算,提供了该试验功率放大器的配置方法。All vehicular EMC laboratories need to carry out testing for road vehicle electromagnetic immunity to off-vehic, le radiation sources in China. This article studied power estimation of the radiated immunity test for different testing severity level during 200-1000 MHz by theoretic analysis and practical measurement, and provided reasonable configuration of power amplifiers for the testing.
