Interface Technology of Auto-Testing System for TWT Transmitter

行波管发射机测量信号的种类繁多,专用自动测试系统应运而生。系统中必须包含多个测试仪表和较为复杂的测量电路与发射机相连,因此,自动测试系统的接口设计和通讯方式的选择是系统测试稳定性的基础和关键。文章通过对系统性能和接口的分析和研究,在进行多次试验的基础上得出一些有关接口技术的相关结论,并提出一种可靠的接口设计和实现方案。

Due to the significant difficulties of the adjustment for large quantities of traveling wave tube （TWT） transmitter, the specific auto-testing system is used increasingly. Various kinds of measured types make the measuring circuit and interface designing of the auto-testing system be more complicated to assure the stability, which is the foundation of the system. The performance and the interfaces are analyzed and several relevant conclusions are given on the base of experiments. It is proposed that a reliable implementation of inter- face designing at last.
