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”.<\/p>\n
