DAB (Digital Audio Broadcasting) is a digital radio technology for broadcasting radio standards. DAB can offer more radio programs over a specific spectrum than analog FM radio and more robust to noise and multi-path fading for mobile listening. The audio quality of DAB is lower than FM stereo due to most stations using a bit rate of 128 Kbits/s or less with the MP2 audio codec. DAB+ is an upgraded version of the DAB system was released in Feb 2007, which is called DAB+. DAB is not compatible with DAB+, which means DAB only receivers will not be able to receive DAB+ signals. DAB+ is approximately twice as efficient as DAB due to the adoption of the AAC+ audio codec and more robust due to the addition of Reed-Solomon error correction coding. N7611B-RFP advanced DAB/DAB+/DMB option simplified the creation of DAB, DAB+, DMB-Audio or T-DMB modulated signal which are fully validated and optimized for RF performance. Easily generate DAB/DAB+/DMB ideal signal or signal with frequency error, clock error, AWGN, I/Q impairments, multi-paths or multi-carriers to test the transmitter component, receiver performance test, receiver chipset design, receiver module integration or receiver manufacturing. Create FM Stereo signals with ETI file or STI interface as payload with seamless playback for subjective test.
This option can be added as a product upgrade.
