研究了无线局域网系统辐射射频电磁场抗扰度测试系统。距离打开的PW单元160 cm处的泄漏电场降低至30 dB，然后不会影响由无线LAN系统组成的AP（接入点）的操作，该无线LAN系统与安装在PW单元中的EUT（受试设备）进行通信。插入PW信元后，BUT与AP之间的归一化站点衰减（NSA）仅发生几dB的变化，因此可以认为PW信元对无线通信系统的电波特性影响很小，可以忽略不计。此外，我们尝试测量干扰波的施加水平对无线LAN系统IEEE802.11b和IEEE802.11g的吞吐量的依赖性。其结果是，它被证实，无线局域网系统的辐射射频电磁场抗扰度测试系统可以组成使用开放的PW细胞，而不会受到影响的印象干扰波。
We study radiated RF (radio-frequency) electromagnetic field immunity test system for wireless LAN system by using opened PW (Parallel Wired) cell, in which metal cover is removed. Leakage electric field at distance of 160cm from the opened PW cell decreases until 30 dB, and then does not affect to operation of the AP (Access Point) composed of the wireless LAN system that communicates EUT (Equipment Under Test) installed in the PW cell. NSA (Normalized Site Attenuation) between BUT and AP changes only several dB by inserting the PW cell, and then it can be concluded that the effect of PW cell for radio wave property of wireless communication system is negligible small. In addition, we try to measure dependencies of impressing level of disturbance wave on a throughput of wireless LAN systems IEEE802.11b and IEEE802.11g. As a result, it is confirmed that the radiated RF electromagnetic field immunity test system for wireless LAN system can be composed by using the opened PW cell without affecting from impressing disturbance wave.
