无线电数据系统(RDS).接收器产品和特征.测量方法

[中文适用范围]： 本国际标准描述了如何测量涉及三个 RDS 接收器产品类别的最低 RDS 接收器性能要求。然而，应该指出的是，市场上也有一些 RDS 接收器产品的性能明显超出了所引用的最低 RDS 接收器性能要求。然而，通过 AF 列表实现自动程序服务跟踪的方法和算法是针对客户和制造商的，因此不包含在本标准中。 [外文原描述]： IEC 62634:2015 describes how to measure minimum RDS receiver performance requirements which concern three RDS receiver product categories. However, it should be noted that there are also RDS receiver products on the market that significantly out-perform the minimum RDS receiver performance requirements quoted. This second edition cancels and replaces the first edition published in 2011 and constitutes a technical revision. It includes the following changes: - the 100 kHz test measurement case from Clause 8 of IEC 62634:2011 was deleted as it did not permit to achieve stable and reproducible measurement results; - an error has been corrected. The term "de-emphasis" shall read correctly "pre-emphasis".
