This paper describes the basic principle and typical working sequence of communication between multi-channel ADC and PC, and proposes a multi-channel analyzer PC interface design based on DMA technology. The multi-channel The analyzer’s results in measuring 13 7Cs scintillation gamma spectroscopy proved it to be a practical method for high-speed communications between multi-channel ADCs and PCs.
