产品简介:
1211型电流前置放大器是为满足现代化实验室技术参数需求而专门设计的。
它能测量范围在10-2到10-12安培的满量程灵敏度电流。其动态范围可达96dB,输出稳定度优于0.003%/℃,且它的增益稳定度优于0.05%/℃。其经典的模拟电路设计提供了一个不受任何干扰的信号,而不像基于微处理器的多路前面板显示设计那样,在高频情况下会遇到“噪声干扰”问题。该款宽增益带宽产品提供了校准功能,并且其前面板上的上升时间可从10μs设置到1s。
The Model 1211 Current Preamplifier was designed to provide all of the features required of a modern laboratory preamplifier. It measures current with full scale sensitivity ranging from 10-2 to 10-12 amperes. With a dynamic range of 96dB and output stability better than 0.003% per o C or per day plus a gain stability of 0.05% per o C of per day, its performance is unexcelled.
