DigiLock 110具有多个数字控制器。 PID参数，带宽等可以数字方式输入。用户可以轻松地返回经过验证的参数集，并以明确的步骤更改参数。使用给定的参数，DigiLock可以计算控制器的幅度和相位频率响应并可视化，这是优化锁定性能的有用工具，尤其是在与频谱和网络分析结合使用时。

DigiLock 110自动锁定功能可同时控制多个PID和模拟P。它将激光扫描到所需的锁定点，并在适当的时候启用所有PID。 DigiLock可以通过多种方法检测正确的锁定，仅在某些情况下允许锁定，一旦脱离锁定，则尝试以定义良好且受控的方式重新锁定。这种智能使锁定激光器更加舒适，并为用户最大化了测量时间。

DigiLock 110模块以多种方式为用户提供支持。在优化激光锁定参数时，查看误差信号的频谱是很有用的。 DigiLock不仅可以显示时间信号，还可以显示信号的频谱。可以轻松检测到振荡并分析残留的激光噪声。同样，在选择转角，调制和滤波器频率时，激光器中执行器的频率响应也起着重要作用。 DigiLock 还可以提供网络分析功能，用于确定执行器带宽和谐振频率。

Additional Information
DigiLock 110模块使激光锁定变得容易。许多支持功能可帮助初学者和专家。选择频谱中的斜率或峰值后，软件可以在连续扫描激光时跟踪此功能。只需单击鼠标，激光就会扫描到所需的锁定点并在用户想要的确切位置激活该锁定。
DigiLock 110模块提供了边缘锁定的Lock-In和Pound-Drever-Hall技术。两种技术都可以对激光频率和测得的光电二极管信号进行调制/解调。调制频率是可变的，对于锁定模块，调制频率高达780 kHz，对于Pound-Drever-Hall模块，调制频率高达25 MHz。这些高调制频率允许更高的锁定带宽，因此可以提供更稳定的锁定。
