Abstract

This paper presents a configurable radio frequency reference noise source and its radiated emission (RE) simulation model. This noise source is representative of actual PLC and IO products with a High Speed Gigabit backplane. It is designed to produce a reference noise signature from 30 MHz to 6GHz with radiated emission levels close to the class A electromagnetic radiation disturbance limits of CISPR 11 and CISPR 22. A radiated emission model of this noise source was established to investigate design factors. Multiple emissions scans were performed in two separate semi-anechoic chambers located in different facilities in order to test the repeatability of this noise source. Measurement results indicated that the noise source has very good repeatability and that it can serve as a reference noise source. The results were also used to evaluate the maturity of the simulation technology, as well as, to quantify the difference between chambers.

可配置参考射频源及其场地相关辐射发射模型

提出了一种可配置射频参考噪声源及其辐射发射仿真模型。该噪声源是具有高速千兆背板的实际PLC和IO产品的代表。它的设计目的是产生30 MHz至6GHz的参考噪声特征，其辐射发射水平接近CISPR 11和CISPR 22的a类电磁辐射干扰限制。建立了该噪声源的辐射发射模型，探讨了设计因素。为了测试该噪声源的可重复性，在位于不同设施的两个独立的半消声室中进行了多次发射扫描。测量结果表明，该噪声源具有很好的重复性，可以作为参考噪声源。结果还用于评估模拟技术的成熟度，以及量化不同腔室之间的差异。
