DABRF Receiver & Analyser

The DABRF device was developed as a core component of the tunnel break-in system, MAGIC TBR, that, in the event of a disaster, allows supplying a street tunnel with live warning messages via digital radio.
All digital signal processing functions are implemented in one powerful DSP and one FPGA. A Gigabit Ethernet interface and 512 MByte internal memory enable a wideband connection between the DABRF and a PC or other external system components. The so created device is versatile and suitable for other applications as well.
In particular, the DABRF replaces the established DAB test receiver, UEB400-DXP, within the DAB-XPlorer family. The DABRF offers great extensions of the powerful analysis tools of the DAB-XPlorer suite. It will support the already known functions:

• Recording of ETI data streams from a
• received on-air signal
• Multiplex analysis
• Coverage measuring with bit error rates and RF level,
• SFN analysis

Additionally, it will enable the following new functions to be realized by software extensions:

• RF recording in form of I/Q samples at a bandwidth of 1.6 MHz
• Replay of the recorded RF signal with a high dynamic range
• Simultaneous COFDM modulation of up to four different ETI or EDI data streams to four DAB blocks laying within a 37 MHz wide RF band
• Advanced RF analysis of the received signal, i.e. MER, inband spectrum, constellation diagram, channel impulse response etc.
