To solve the problem that it is not convenient for testing radio modem communication performance under field en⁃vironment,the design method of portable testing system for radio modem is proposed. The system consists of lithium polymer bat⁃tery,power management module,main control chip and radio station communication interface module. Testing data can be pro⁃vided for radio modem to satisfy system demands by programming on system main control chip. Test results show that the system can complete the test for radio modem with multiple performances in no signal source complex environment. The system has the characteristics of good portability,high practicability and stable working.%为解决在外场条件下不便于测试数传电台通信性能的问题，提出了便携式数传电台测试系统的设计思路。该系统由锂聚合物电池、电源管理模块、主控芯片、电台通信接口模块等部分组成，通过对系统主控芯片编程可为数传电台提供测试数据以满足要求。试验结果表明：该系统能够在外部无源的复杂环境中完成对多种性能数传电台的测试，具有便携性、实用性、工作稳定的特点。
