Newport125 MHz Fiber-Optic Receivers
These 125 MHz fiber-optic receivers offer a well-balanced combination of gain, bandwidth, and low noise over the DC–125-MHz frequency range. Because of their high transimpedance gain and low noise-equivalent power (NEP), they offer the best in sensitivity for signals with rise and fall times as short as 3 ns. This high sensitivity, combined with their high-level output, reduces the effects of downstream noise sources. They have been engineered to eliminate most common sources of noise and drift, and have enough gain to pick up even very weak signals making them ideal optical front ends for systems requiring a low-noise input.

高跨阻增益和低噪声
具备高跨阻抗增益和低噪声等效功率 (NEP) 的特点,可提供佳信号灵敏度,上升沿和下降沿时间短 3 ns。这种高灵敏度,结合其高阶输出,可减少下游噪声源的影响。
直流耦合版本
利用的直流耦合,这些光接收器对瞬态信号给出线性响应,而没有人工振荡、尾部或其它异常。
交流耦合版本
具有 25 kHz 低频衰减的交流耦合版本。这些光接收器可用于测量大型 cw 组件上的小交流信号。为了使对准更容易,交流耦合版本配备了直流光电流监测器输出。监视器输出具有 50 kHz 带宽和 1 V/mA 的增益。
射频屏蔽
即使在使用调 Q 激光器和其它噪声设备的实验室中,缜密的射频屏蔽和电源输入滤波也能消除电磁干扰。
