PROBLEM TO BE SOLVED: To provide a digital signal collection system that can simply collect high-speed digital data on which a plurality of channels are multiplexed in a communication base station unit or the like so as to analyze the data. SOLUTION: In the case of monitoring a digital signal at a prescribed observing point in a card 101 to be collected, the digital signal at the observation point is collected in real time and stored in a memory 2, the digital data stored in the memory 2 are read and transferred to an analysis section 2 with a data analysis function such as a personal computer and the analysis result is displayed. Thus, it is not required to build in a test program as an F/W in a DSP (CPU) in the card 101 to be collected without the need for using a test device such as a logic analyzer so as to simply collect the digital signal. |
