Abstract: PURPOSE: A concurrent multiple defense threatening signal generating device is provided to simulate the performance of electronic battle equipment in an experiment lab. CONSTITUTION: A signal generator(120) simultaneously generates a multiple defense threatening signal under the control of a sub controller(110). A signal distributer(130) distributes a generated threatening signal to a plurality of channels. An output part simultaneously outputs a divided threatening signal with multiple. A main controller(150) transmits a control command to the sub controller for the concurrent occurrence of the multiple defense threatening signal.

Abstract translation: 目的：提供并发的多重防御威胁信号发生装置，以模拟实验实验室中电子战斗设备的性能。 构成：信号发生器（120）在子控制器（110）的控制下同时产生多重威胁威胁信号。 信号分配器（130）将产生的威胁信号分配给多个信道。 输出部分同时输出多个分割的威胁信号。 主控制器（150）向副控制器发送控制命令以同时发生多重防御威胁信号。
