進(jìn)口電流放大器美國DL1211型前置放大器+M104電池
產(chǎn)品簡介：
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.
1211型電流前置放大器是為滿足現(xiàn)代化實驗室技術(shù)參數(shù)需求而專門設(shè)計的。
它能測量范圍在10-2到10-12安培的滿量程靈敏度電流。其動態(tài)范圍可達(dá)96dB，輸出穩(wěn)定度優(yōu)于0.003％/℃，且它的增益穩(wěn)定度優(yōu)于0.05％/℃。其經(jīng)典的模擬電路設(shè)計提供了一個不受任何干擾的信號，而不像基于微處理器的多路前面板顯示設(shè)計那樣，在高頻情況下會遇到“噪聲干擾”問題。該款寬增益帶寬產(chǎn)品提供了校準(zhǔn)功能，并且其前面板上的上升時間可從10μs設(shè)置到1s。
基本參數(shù)
靈敏度：10－3到10－11 I/V 九級可選；
增益： 輸出增益三檔可調(diào)，×0.1、×1、×10；
輸入偏移電流：小于0.5×10－13A @50℃；典型，1×10－14A @25℃
