DABSTOR Logger logo

DABSTOR Logger continuously records up to 4 input streams to capture a rolling history of multiplexer outputs to transmission networks or inputs at transmitter sites.


Endless-loop recording of ETI files can provide government regulators and multiplex operators access to synchronised evidence of previously broadcast DAB/DAB+ audio and data content.  Other applications include the use of ETI files from a specific date and time to support development, testing and troubleshooting of DAB/DAB+ receivers, transmitters, monitors, analysers, encoders and multiplexers.

Input options include ETI, EDI and RF.
