介绍了一种新一代射频辐射抗扰度/敏感度试验的旋转电磁场方法及其基本特点。在免疫/药敏试验中，需要两种不同的双边带抑制载波（DSB-SC）信号来产生缓慢衰减的电磁场。这些DSB-SC信号产生的DSB-SC信号发生器的基础上的新概念，它包括电压可变衰减器，双相开关，直接数字合成器和微处理器。使用DSB-SC信号发生器，可以比传统系统更容易地产生任意RF频率的DSB-SC信号。本文阐述了DSB-SC信号发生器的原理及产生的DSB-SC信号的基本特性。使用新的概念产生的测量的基本特性的电磁场，它被证实，该领域可以应用于射频抗扰度/敏感性测试。最后，以某被测设备的敏感性试验为例，验证了该系统的有效性。
A new generation method of rotating electromagnetic fields (rotating-EM fields) for radio frequency (RF) radiated immunity/susceptibility test and its basic characteristics are described. Two different double-side-band suppressed-carrier (DSB-SC) signals are required for generating the slowly rotating-EM field for the immuntty/susceptibility test. These DSB-SC signals are generated by a DSB-SC-signal generator based on the new concept which consists of voltage-variable attenuators, bi-phase switches, a direct-digital synthesizer and a micro processor. Using the DSB-SC-signal generator, the DSB-SC signal of arbitrary RF frequency can be generated more easily than the conventional system. In this paper, the principle of the DSB-SC signal generator and the basic characteristics of the DSB-SC signals generated by the generator are clarified. The measured basic characteristics of the rotating-EM field generated using the new concept are shown and it is confirmed that the field can be applied for the RF immunity/susceptibility test. In addition, the susceptibility test of an equipment under test is made as an example, the validity of our proposed system is established.
