ETI (or MDI) files describe the characteristics of a signal suitable for transporting a full DAB Ensemble (or DRM Multiplex), where the ETI comprises a number of subchannels and a formatted Fast Information Channel (FIC) between a DAB Ensemble provider and a transmission network provider, and the MDI comprises a number of streams and a formatted Service Description Channel (SDC) between a DRM Multiplex provider and a transmission network provider. It means that if a specific broadcasting station’s T-DMB/DAB (or DRM) signal is recorded as an ETI (or MDI) file, the recorded file contains all the information about the station. Using the RWC2010M’s ETI/MDI player function with these files, specific broadcasting stations’ T-DMB/DAB signals or DRM signals can be easily regenerated in labs. The RWC2010M also provides analog functions as AM/FM transmission and audio analyzer. It also provides RDS functionality as a way to play pre-encoded RDS files.
It can be operated stand-alone, and also can be controlled and played with the RWC2010x PC application. The RWC2010x PC application provides various control and measurement functions such as file handling, AM/FM setting, remote controlling and gathering audio measurement data from RWC2010M. Audio measurement data includes SINAD, SNR, THD, waveform and spectrum.
