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

按照对地目标探测一般,常采用纳秒到十纳秒量级电磁探测窄冲,信号频谱具有从直流低频直到千兆赫带。

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，从直流到千兆赫类比、混合信号、射频、光纤、微控制器及信IC均有。
