Digital Modulation of Several FM Multiplexes
With RDS and TMC Encoder
Car radios are analogue radios: FM will most probably remain the most important transmission mode for mobile radio reception for a long time. In the meantime, administration and additional services for mobile radio receivers become more and more complex: Channel lists, alternative frequency handover, programme and traffic information are essential parts of the Radio Data System (RDS). The car radio must be able to receive and process this information as well as TMC information most reliably.
To evaluate the RDS and TMC functions' quality, maintech offers the MultiFM-Modulator. The device modulates up to 24 stereo multiplexes and provides best conditions to simulate a mobile operating of the car radio receiver and to test its RDS and TMC software. Automatic frequency changes and channel handovers can be evaluated optimally as well as the handling of TMC information.
