（RDS/RBDS,DARC/RTIC）FM Multiplex Signal Generator

（RDS/RBDS,DARC/RTIC）

MSG-2174 is an FM multiplex signal generator adopted a multiple module method.Combination of DARC modulator, RDS modulator, and FM stereo modulator can be chosen depending on usage of user.DARC-VICS/RTIC FM multiplex method and RDS/RBDS FM multiplex method are available by this one unit, moreover a stereo modulator can be installed in same casing.By using application software attached to this unit, new data can be created and edited by a PC simply.This unit can output the data by being downloaded.Regarding DARC encoder function, we reduced its size by modifying Basic specifications ofMSG-2170/2173 and achieved cost reduction.As for RDS function, usability for production line was prioritized because it is an existing method.

MSG-2175 is an FM multiplex signal generator equipped with function for stereo modulating as standard.RDS/RBDS and DARC modulators can be combined by user’s needs.By using application software attached to this unit, new data can be created and edited by a PC simply.This unit can output the data by being downloaded.
