This paper studies the TETRA digital trunking base station and mobile terminal RF consistency automatic test system based on LabVIEW platform, including system design, system implementation, system testing and performance analysis. The main program and control panel are designed, and the TETRA base station and mobile terminal RF consistency test are realized through PXIe-5644R signal generator and 6015 data acquisition card. The experimental results show that the system can effectively carry out TETRA digital trunking base station and mobile terminal RF consistency test with high testing accuracy and stability. At the same time, this paper also analyzes the performance of the system and the problems existing in it, and puts forward improvement measures for the follow-up work.【Keywords】TETRA; digital trunking communication system; LabVIEW; automatic test system; RF consistency
