摘要
针对星间链路收发信机各项性能指标测试的需求,设计实现了测试场景可配置、测试覆盖率高的测试系统,提出收发信机测试系统的设计原则;测试系统采用通用仪器和自行研制设备相结合的方式,具有模拟收发信机外围接口的功能,并能有效评估收发信机的各项功能性能;同时采用LabVIEW开发的上位机软件能够对不同测试场景进行灵活的配置,提供友好的人机交互界面;实验结果表明,设计的收发信机测距精度达到分米级,测试系统满足收发信机的测试需求。
For each performance index of inter-- satellite link transceiver testing requirements, design and implementation of test scenari- os can be configured, with high test coverage test system, this paper puts forward the design principles of transceiver test system. Test sys tern adopts the universal instruments and self--made equipment combination, with analog transceiver peripheral interface functions, and can effectively evaluate the function and performance of transceiver. At the same time using PC software developed by LabVIEW can be to flexi ble configuration for different test scenarios, with a friendly man--machine interface. The experimental results show that transceiver can a- chieve decimeter accuracy and test system can meet the test requirements of transceiver.
