To meet the practical needs of engineering test along the high-speed railway, we proposed the design for the system of GSM-R electromagnetic environment test. Through the interface programming technique, the computer takes remote control for the ESPI and GPS and other instruments, thus, the functions of real-time acquisition, display and storage of GSM-R electromagnetic environment data are achieved．Consequently, the electromagnetic environment quality evaluation can be gained with the playback and processing of data in the selected test bands and area.
