TeraFlash pro

多功能时域太赫兹平台

0 dB峰值动态范围，> 6 THz带宽
太赫兹可变路径长度在15cm 至110cm之间
快速振荡器 – 60 traces/s @ 50 ps
新增功能：“Dual”版本，适用于2对发射器/接收器

TeraFlash pro是台式时域太赫兹平台，它在动态范围，带宽和测量速度方面树立了新的标准。由于先进的激光设计和光电导天线的发展，该系统现在实现了100 dB的峰值动态范围和超过6 THz的带宽。由于具有高度精确的机械延迟级，该系统在50 ps扫描范围内可获取60条迹线/秒，或在20 ps处获得95条迹线/秒。新的“Dual”版本可同时操作两个发射器和/或两个接收器。
