Belar RDS-1 RDS Monitor And Decoder



The RDS-1 is a fully-featured RDS/RBDS monitor and decoder that incorporates both the RBDS standard in the U.S. and the RDS standard in Europe and other countries. The RDS-1 is essential to monitor critical RDS parameters, such as RDS injection and the phase relationship between the RDS subcarrier and the stereo pilot. The RDS-1 decodes all the major group types and provides the data in fully decoded and hexidecimal formats. An RS-232 interface and a Wizard interface are built in to the RDS-1, for easy remote communication and full-screen displays.
