无线电干扰和抗扰度测量仪器和方法规范第3部分:CISPR技术报告

[中文适用范围]： 本国际技术报告提供了关于无线电干扰和抗扰度测量装置及方法的第3部分：CISPR技术报告的详细信息。该部分涵盖了与具有不同于CISPR特性的装置进行的测量之间的相关性、干扰模拟器、开阔试验场与混响室限值之间的关系、电话用户线中由中短波广播发射机感应出的不对称干扰源的特征描述、垂直方向辐射的可预测性（30 MHz以上和30 MHz以下）、干扰的幅值概率分布特性与数字通信系统性能之间的相关性、均方根平均加权检测器的定义背景、共模吸收器件（CMAD）、基于FFT的接收机、电信端口的信号参数以及CDNE设备和测量方法的背景材料。 [外文原描述]： CISPR TR 16-3:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. CISPR 16-3:2020 is a collection of technical reports (Clause 4) that serve as background and supporting information for the various other standards and technical reports in CISPR 16 series. In addition, background information is provided on the history of CISPR, as well as a historical reference on the measurement of interference power from household and similar appliances in the VHF range (Clause 5). Over the years, CISPR prepared a number of recommendations and reports that have significant technical merit but were not generally available. Reports and recommendations were for some time published in CISPR 7 and CISPR 8. At its meeting in Campinas, Brazil, in 1988, CISPR subcommittee A agreed on the table of contents of CISPR 16-3, and to publish the reports for posterity by giving the reports a permanent place in CISPR 16-3. With the reorganization of CISPR 16 in 2003, the significance of CISPR limits material was moved to CISPR 16-4-3, whereas recommendations on statistics of disturbance complaints and on the report on the determination of limits were moved to CISPR 16‑4-4:2007. The contents of Amendment 1 (2002) of CISPR 16-3:2000 were moved to CISPR 16-4-1. NOTE As a consolidated collection of independent technical reports, this document can contain symbols that have differing meanings from one clause to the next. Attempts have been made to minimize this to the extent possible at the time of editing. This fourth edition cancels and replaces the third edition published in 2015. This edition constitutes a technical revision. The main technical change with respect to the previous edition consists of the addition of detailed background information on the large loop antenna system (LLAS) and its measurement method in general and on the models and equations which apply to calculate the reference validation factor and conversion factor curves.
