This article introduces the design and the test of ADC sampling system based on the readout electronics for GEM detector. The system consists of an analog to digital converter module, a data collection module and a backend data receiving module. The analog to digital converter module is presented in detail, including hardware circuit design, FPGA firmware design, optical fiber data transmission design and ADC performance test. After testing, the system implements 8 - channel real - time data sampling, transfer, storage and display, and the system works well.
