介绍了数字T／R组件的基本概念和同步在其测试中的作用，并对发射通道相位一致性、脉内信杂比、接收延时等测试过程中数字T／R组件和测量仪器设备同步的实现方法进行了详细阐述。经试验验证表明：以产生的同步信号为纽带，先实现与数字T／R组件的同步，再利用该信号实现与测试仪器的同步，从而间接实现数字 T／R组件和测试仪器同步的方法有效可行。在此同步体制下，可以分别利用测试仪器的多通道相参机、时间门和内部触发模式的脉冲调制功能实现性能参数的测试，这也为其他脉冲体制电子装备的测试提供了有益的参考和借鉴。

T his paper introduces the basic conception of digital T/R module and the role of synchronization in test and measurement (T&M ) for digital T/R module firstly ,and then expounds the realization method of synchronization be‐tween the digital T/R module and T&M instruments in the testing process of phase consistency between transmission channels ,intrapulse signal‐noise ratio (SNR) and receiving delay etc .With the verification of experimentation ,it is ef‐fective and feasible that synchronization signal from the automatic test system (ATS) synchronizes the digital T/R mod‐ule and T&M instruments respectively ,and then achieves synchronization between the digital T/R module and T&M in‐struments .With the method in this paper ,the performance testing for digital T/R module can be realized by combination of multi‐channel coherent receiver ,time‐gate and pulse modulation based on internal trigger .It also provides an useful reference and T&M solution for other pulse electronic equipments system .
