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

SIM954 放大器是一款 300 MHz、雙通道反相放大器，可提供高達 ±10 V 的輸出電壓和高達 1 A 的輸出電流。該放大器可用于驅動多種類型的輕型實驗室負載（包括電感和電容負載），而不會受到典型射頻功率放大器的限制和高成本。SRS SIM954 300 MHz 雙通道放大器 測量

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

SIM965 模擬濾波器非常適合需要貝塞爾或巴特沃斯濾波器的信號調節應用。貝塞爾濾波器提供清晰的階躍響應（可忽略的過沖）和線性相位響應，而巴特沃斯濾波器提供通帶平坦度和一些過沖。 從前面板可以選擇高通或低通濾波。SIM965 SRS STANFORD 模擬濾波器測試
