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.

系由三维运动平台、带间隙伺服加工头、纳秒脉宽等脉宽晶体管脉冲电源及环境保障系。

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要,通常采用纳秒到十纳秒电磁探测窄脉冲,信号频谱具有从直流低频直到千兆赫兹宽带。
