摘要

新版CISPR 22/EN 55022和CISPR 24/EN 55024要求对信息技术设备(ITE)和电信设备的电信端口进行发射和抗扰度测试。不同的一致性选择和电缆类别需要不同版本的阻抗稳定网络(ISNs)。由于西方RJ45连接器的不同引脚连接的系统种类繁多，因此选择了使用通用接口和一系列适配器的基本通用网络的解决方案。开发了一种用于验证和校准的高性能平衡器。讨论了CISPR 22标准的不完善之处，以及CISPR 16-1的特点和对ISN表征和校准的建议修订。

Measurement of emissions and immunity on telecommunication lines-a universal ISN concept for unshielded cables

The new editions of CISPR 22/EN 55022 as well as CISPR 24/EN 55024 require testing of emission and immunity on telecommunication ports of information technology equipment (ITE) and telecommunication equipment. Different versions of impedance stabilization networks (ISNs) are required for the different conformance alternatives and cable categories. Since there is a great variety of systems with different pin connections of the Western RJ45 connector, a solution with a basic universal network using a universal interface and a series of adapters has been chosen. A high-performance balun has been developed for verification and calibration. Imperfections of the CISPR 22 standard are discussed together with characteristics and proposed amendments of CISPR 16-1 for ISN characterization and calibration.
