 DLPCA-200 BANDWIDTH


The bandwidth of an ideal variable gain amplifier is independent of the gain setting which is very important for measuring fast signals and pulses. The bandwidth of FEMTO's DLPVA Amplifiers remains constant at 100 kHz (-3 dB) up to the highest gain setting. Wideband noise can be reduced by switching the upper cut-off-frequency to 1 kHz.

 

DLPCA-200可变增益放大器根据本身的特性包装,使用范围宽广,可以使小电流转化成可用电压。它非常适合,例如,为解决当前的时间和电荷的测量到微秒区域和作为前置放大器为光电二极管或锁在系统。DLPCA-200提供可变增益值从103到1011V/A,在微微毫 amp 系列允许电流敏感测量。有开关控制的AC/DC耦合,10Hz低通滤波器和可调节偏压控制科用于改变放大器的不同测量任务和信号状态。可调偏置电压连接到输入插座的盾提供优化的外部二极管连接到放大电路的输入速度和噪音性能。
