PROBLEM TO BE SOLVED: To provide a digital audio broadcast DAB signal collection device that efficiently collects a DAB signal required to evaluate a DAB receiver from serial data demodulated by the DAB receiver regardless of a small circuit scale. SOLUTION: The DAB signal collection device that collects required data from serial data demodulated by a DAB receiver receiving a digital audio broadcast is provided with an input processing means 1 that extracts a receiver data interface RDI signal from the serial data, an input buffer 2 that stores the extracted RDI signal, an analysis means 3 that extracts optional data from this RDI signal, an output buffer 4 that stores the extracted data, and a recording means 5 that reads the data from the output buffer 4, generates a file and records and stores the file. Since most of the data processing is conducted by the analysis means and the recording means records the processed data, the data processing load of the recording means can be relieved.
