New! 带宽可调谐滤波器 OTF-980

OTF-980
OTF-980是一款支持中心波长和带宽独立可调谐的滤波器,对应C&L波段的可调谐范围。采用空间光学设计实现超窄线宽调谐,可以通过精细调节实现想要的波形。

 

 

概要

根据不同的需求,该产品根据C&L-band带宽调节范围和边缘陡峭度分为3种版本。其中,超精细调节版本(Ultrafine-Plus)的边缘陡峭度可达到1000dB/nm。可以通过远程控制或触摸面板实现带宽及中心波长的设置,内置的功率监控器可以找出滤波带宽中的峰值功率;支持的控制接口有:GPIB、网口、USB,兼容SCPI标准。OTF-980也可以通过触摸面板控制。
