摘　　要：针对飞行器半实物仿真试验中1553B接口伺服系统的频率特性不能通过1250频率响应分析仪进行测试的问题,提出了仿真专用频率特性测试仪的设计方案。该方案采用计算机采集加软件处理的虚拟仪器思想,硬件基于仿真试验系统已有条件,软件采用Win32+RTX设计模式,处理算法使用正弦扫描法。搭建测试验证环境对测试准确性进行了验证,测试验证和实际应用表明其测试结果具有较高精度,能够满足实际使用要求。For frequency characteristics of1553B interface servo system can not be tested by 1250frequency response analyzer, a design scheme of simulation special frequency characteristic tester is proposed. The idea of virtual instrument that uses computer acquisition and software processing is adopted in the program. Hardware is based on existing conditions of the simulation system and Win32 ＋ RTX design patterns is used for developing software. A test environment is built to verify the test accuracy. The test results show that the fairly good precision of tester is achieved in the test validation and practical application and can fulfill the user requirements.
