IEC 62634:2011 describes how to measure minimum RDS receiver performance requirements which concern three RDS receiver product categories. 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. Methods and algorithms to achieve automatic programme service-following by means of AF lists are customer- and manufacturer-specific, and are therefore not covered in this standard. It cancels and replaces IEC 60315-9, published in 1996, and constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60315-9:
- use of state-of-the-art measuring methods based on today's RDS products;
- provision of realistic performance targets;
- is complementary to RDS standard IEC 62106 (2009);
- it covers the challenging RDS receiving conditions "weak signal", "adjacent channel" and "strong signal" to verify the required RDS sensitivity and selectivity for three different RDS product categories.
