产品参数

SR510/SR530锁相放大器
SR510 和 SR530 是模拟锁相放大器，可在噪声水平远高于信号的环境中，测量低至纳伏级的微弱交流信号。

单相 SR510 与双相 SR530 均配备低噪声电压、电流输入端口，具备高动态储备、两级时间常数设置，且内置振荡器。此外，两款锁相放大器均搭载多项人性化设计，操作简便易用。

SR510/SR530 的核心部件为精密模拟正弦波乘法器。锁相放大器通过乘法器(解调器)，将参考频率下的输入信号转换为直流信号，以便后续滤波与放大。多数锁相放大器采用方波乘法器，会引入杂散谐波响应;而 SR510/SR530 采用纯净正弦波乘法器，从原理上杜绝了无用谐波的产生。
