srs CTC100-Cryogenic temperature controller，Introducing the new CTC100 Cryogenic Temperature Controller

SIM954 放大器是一款 300 MHz、双通道反相放大器，可提供高达 ±10 V 的输出电压和高达 1 A 的输出电流。该放大器可用于驱动多种类型的轻型实验室负载（包括电感和电容负载），而不会受到典型射频功率放大器的限制和高成本。SRS SIM954 300 MHz 双通道放大器 测量

srs SIM964-1 MHz analog limiter,The SIM964 Analog Limiter provides upper and lower voltage limits for conditioning dynamic signals.

SIM965 模拟滤波器非常适合需要贝塞尔或巴特沃斯滤波器的信号调节应用。贝塞尔滤波器提供清晰的阶跃响应（可忽略的过冲）和线性相位响应，而巴特沃斯滤波器提供通带平坦度和一些过冲。 从前面板可以选择高通或低通滤波。SIM965 SRS STANFORD 模拟滤波器测试
