Introduction to DAB technology
DAB not only provides audio coverage, but also opens the doors to multimedia broadcasting with the possibility of including graphic files, highway maps, etc, that can be of great aid en-route. We can foretell a great future for DAB digital radio.
As has already occurred previously with DTT, PROMAX is ahead of the needs of the market and includes specific measurement functions for the new technology. The DAB functions are perfectly integrated to the equipment interface and they can be controlled either by using the keyboard or remotely for the development of automated control and surveillance systems.
PROLINK Premium: Specific Functions for DAB
By selecting the DAB function the measurement screen is accessed, where it is possible to see the reception quality information at a glance. Two graphic bars show the SNR (Signal to Noise Ratio) and the erroneous bits rate (CODED BER). Also, the number of times that the signal may have been lost, the present frequency (or channel) and information relating to the radio station and multiplex, is shown.
PROLINK Premium allows specific active audio information to be selected for viewing; the complete data is shown on the screen for identification, as well as the signal codification format.
PROLINK Premium as a DAB receiver
During the entire time that the DAB measurement is active it is possible to listen to the tuned-in station emission through the apparatus internal loudspeaker. You only need to choose the digital multiplex, the type of service and the channel that you wish to listen to, in order to convert the PROLINK Premium into a digital radio DAB receiver.
