Application Notes:
FM Stereo Radio MPX with RDS testing
The ability to generate an FM Multiplex (MPX) for stereo FM radio reception testing is made possible by the extended audio bandwidth of the dScope Series III audio analyzer. This application note is an introduction to the process of creating an FM multiplex that enables the dScope to test FM stereo radio reception with the simple addition of an FM exciter. The inclusion of an RDS (Radio Data System) subcarrier allows the dScope to facilitate the testing of simple RDS functionality.
