For general exploringobjects requirement, narrow pulse signal with tens millimicro second to millimicrosecond has the frequency spectrum from DC to thousands MHz.

按目标探测的一般需要,通常采用纳秒到十纳秒量级的电磁探测窄冲,信号频谱具有低频到千兆赫兹的宽带。

For one is beautiful is the brand, from direct current to gigacycle per second analogy, the composite signal, the radio frequency, the optical fiber, the micro controller and corresponds IC to have.

为一美系品牌，到千兆赫的类比、混合信号、射频、光纤、微控制器及通信IC均有。
