被动射频和微波器件，互调级测量 - 第一部分：一般要求与测试方法

[中文适用范围]： IEC 62037-1:2025 RLV 包含官方 IEC 国际标准及其 Redline 版本。Redline 版本仅提供英文版，可让您快速轻松地比较官方 IEC 标准与其先前版本之间的所有更改。IEC 62037-1:2025 涉及无源射频和微波组件互调 (IM) 电平测量的一般要求和测量方法，这种互调可能是由两个或多个发射信号的存在引起的。本文档中给出的测试程序给出了使用两个发射信号表征不需要的 IM 信号电平所需的一般要求和测量方法。IEC 62037 系列涉及 PIM 的测量，但不涵盖产品在性能方面的长期可靠性。第三版取消并取代了 2021 年发布的第二版。此版本构成技术修订。此版本与前一版本相比包括以下重大技术变化：a) 进一步说明 PIM 生成通常与频率有关，并指出使用扫频或多个固定频率进行测试通常会提供更准确的结果；b) 将多端口 PIM 分析仪确定为一种可能的测试设置拓扑；c) 增加了测试功率水平不超过 DUT 功率处理能力的规范；d) 更新了测试规范，以包括正确定义 PIM 测试所需的缺失参数；e) 进一步说明 PIM 测试报告包括在测试持续时间内测得的最大 PIM 值；f) 更正了图 3 中在 IEC 62037-1:2021 中错误更改的错误。 [外文原描述]： IEC 62037-1:2025 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. IEC 62037-1:2025 deals with the general requirements and measuring methods for intermodulation (IM) level measurement of passive RF and microwave components, which can be caused by the presence of two or more transmitting signals. The test procedures given in this document give the general requirements and measurement methods required to characterize the level of unwanted IM signals using two transmitting signals. The IEC 62037 series addresses the measurement of PIM but does not cover the long-term reliability of a product with reference to its performance. This third edition cancels and replaces the second edition published in 2021. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) added clarification that PIM generation is typically frequency dependent and noted that testing with swept or multiple fixed frequencies often provides more accurate results; b) identified multi-port PIM analyzers as a possible test set-up topography; c) added specification that test power level does not exceed the power handling capability of the DUT; d) updated test specification to include missing parameters needed to properly define a PIM test; e) added clarification that PIM test reports include the maximum PIM value measured over the test duration; f) corrected error in Figure 3 that was erroneously changed in IEC 62037-1:2021.
