摘要
通过对传导抗扰度测试的信号电平控制方法进行分析,表明功率放大器增益的不确定度会导致试验电平的误差。为了避免功率放大器增益所引起的误差影响,对信号电平的控制方法提出改进。通过监测功率放大器的输出功率,调整输出信号的大小,提高传导抗扰度测试的准确性。
Signal level control method for conducted disturbances immunity test is studied in this paper. The results show that the uncertainty of amplifier gain leads to the error of test signal level. In order to avoid the effect of gain error, an improvement in signal level control method is proposed. Output power of amplifier shall be monitored by power meter during test. It can improve the accuracy of conducted disturbances immunity test.
