纳秒

The micro-EDM prototype was composed of three dimensional stage,transistor type isopulse generator with pulse duration of 80ns,and environmental maintaining system.

系统由三维运动平台、带间隙伺服的加工头、纳秒级脉宽的等脉宽晶体管脉冲电源及环境保障系统组。

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

按照对地目标探测的一般要,通常采用纳秒到十纳秒量级的电磁探测窄脉冲,信号频谱具有从直流低频直到千兆赫兹的宽带。
