【摘要】:通过对卫星常用数字接口电路及其传输特性分析,研究了影响接口传输性能的时延、幅值和上升沿特性,提出了一种数字遥测传输接口容差测试方法并研制了测试设备,可以对数字信号进行时延、电平幅值和上升沿的拉偏,实现了接口容差指标的定量测试。通过对卫星单机设备接口拉偏试验,验证了测试方法的正确性和测试设备的实用性。
[Abstract]:Based on the analysis of the digital interface circuit and its transmission characteristics, the characteristics of delay, amplitude and rising edge which affect the transmission performance of the interface are studied. A method for measuring the tolerance of digital telemetry transmission interface is proposed and the testing equipment is developed. The delay, amplitude and rise edge of the digital signal can be deflected, and the interface tolerance index can be measured quantitatively. The correctness of the test method and the practicability of the test equipment are verified by the test of the satellite single equipment interface.
