PX200是一款低噪声高电流线性放大器，用于驱动压电执行器和其他负载。输出电压范围可以是50V至200V的单极性、双极性或非对称电压。有关可用的输出电压范围，请参考规格表。两个放大器可以桥接模式连接，以提供高达+/-200V或+400V的电压。PX200具有高达13安培峰值的高输出电流，非常适合需要高功率和高频率的精密应用。
PX200可以驱动任何负载阻抗，包括无限制的电容性负载，如堆栈执行器；标准压电致动器；两台电线弯曲机；和需要偏压的三线压电弯曲器。偏置电压可以利用与电源电压相连的两个辅助输出来产生。
一系列前面板控制提供了最大的应用灵活性，包括输入信号反转、可变增益、DC偏移和可变电压限制。前面板上的9针DSUB连接器包括用于输入、电压监控、电流监控、关机监控和关机命令的信号。一个四位数的液晶显示屏也显示DC电压。
输出连接器包括BNC、LEMO 00、LEMO 0B.302和插入式螺丝端子。PX200适合广泛的应用，包括电子光学、超声波、振动控制、纳米定位系统和压电电机。

噪音
输出电压噪声包含独立于负载电容的低频成分(0.03 Hz至20Hz)；以及与负载电容近似成反比的高频(20 Hz至1 MHz)分量。
噪声是用SR560低噪声放大器(增益= 1000)、示波器和Agilent 34461A电压表测量的。低频噪声如图2所示。均方根值为120 uV，峰峰值电压为600 uV。
